Answer:

16 unidades preparan simultáneamente 1200 empanadas por día.

Step-by-step explanation:

Si cada fuente tiene una capacidad de 75 empanadas por horneada y que la mayor cantidad posible ocurre cuando el volumen de producción se cocina simultáneamente, entonces el total de fuentes es la cantidad total de producción dividida por la capacidad de empanadas por fuente. Es decir:

[tex]x = \frac{1200\,emp}{75\,\frac{emp}{und} }[/tex]

[tex]x = 16\,unidades[/tex]

16 unidades preparan simultáneamente 1200 empanadas por día.

Answer:

a = 138

Step-by-step explanation:

Notice that from the figure, we can see that ∠MOQ and ∠PON are vertical angles, which means that by definition, they're congruent in measure.

∠MOQ = ∠MOR + ∠ROQ = 90 + 48 = 138°

So, this means that ∠PON is also equal to 138, which means a = 138.

Thus, the answer is a = 138.

Answer:

LSA = 592cm^2.

Step-by-step explanation:

Well LSA is the SA but without the base so the blue square does not count.

So we have to find the area of the triangle which is b*h/2.

So 18.5*16 / 2 is 148.

And since there is 4 triangles with the same dimensions we do 148*4, 592cm^2.

Answer:

False

Answer:

A

Step-by-step explanation:

The perimeter is more since the shape gained many new sides but the area is less because the rectangle lost a little square

Answer:

Option A

Step-by-step explanation:

=> The perimeter is more because there are more sides in figure 2 than in figure 1 and they are more in length too.

=> The area is less since Figure 2 is overlapping which decreases its area than the area of Figure 1 where nothing overlaps.

Answer:

120.7

Step-by-step explanation:

The formula for finding the area of a regular octagon is: A = 2(1+[tex]\sqrt{2}[/tex])[tex]a^{2}[/tex].

Using the formula I got 120.7(rounded).

The area of the regular octagon with a side length of 5 cm is approximately 120.7cm².

We have,

To find the area of a regular octagon with a side length of 5 cm, you can use the following formula:

Area = 2 * (1 + √2) * (Side Length)²

Plugging in the values:

Area = 2 * (1 + √2) * (5 cm)² ≈ 120.7 cm²

Therefore,

The area of the regular octagon with a side length of 5 cm is approximately 120.7cm².

Answer:

Average is less than 65, therefore, shop did not meet the target.

Step-by-step explanation:

The time series graph gives some information about the number of umbrellas sold in a shop in the first six months of 2015.

From the given graph it is clear that the number of umbrellas sold in Jan, Feb, Mar, Apr, May, June are 54, 84, 72, 94, 52, 26 respectively.

Average sales is

[tex]Average=\dfrac{\text{Sum of number of umbrellas sold in 6 months}}{6}[/tex]

[tex]Average=\dfrac{54+84+72+94+52+26}{6}[/tex]

[tex]Average=\dfrac{382}{6}[/tex]

[tex]Average=63.67<65[/tex]

Since, average is less than 65, therefore, shop did not meet the target.

From the time-series, it is found that since the mean is below 65, the shop did not meet the target.

The mean of data-set is the sum of all observations divided by the number of observations.

From the time-series, there are 6 observations: 55, 85, 72, 90, 52, 25.

Hence, the mean is:

[tex]M - \frac{55 + 85 + 72 + 90 + 52 + 25}{6} = 63.2[/tex]

Since the mean is below 65, the shop did not meet the target.

Answer:

Explained below.

Step-by-step explanation:

The data provided is as follows:

S = {31.5, 36.0, 37.8, 38.5, 40.1, 42.2, 34.2, 36.2, 38.1, 38.7, 40.6, 42.5, 34.7. 37.3, 38.2, 39.5, 41.4, 43.4, 35.6, 37.6, 38.4, 39.6, 41.7, 49.3}

Compute the mean and standard deviation as follows:

[tex]\mu=\frac{1}{n}\sum X=\frac{1}{24}\times [31.5+36.0+37.8+...+49.3]=38.88\\\\\sigma=\sqrt{\frac{1}{n-1}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{24-1}\times 299.639584}=3.61[/tex]

(a)

Compute the​ z-score corresponding to the individual who obtained 32.3 miles per gallon as follows:

[tex]z=\frac{X-\mu}{\sigma}[/tex]

  [tex]=\frac{32.3-38.88}{3.61}\\\\=-1.823[/tex]

Thus, the z-score corresponding to the individual who obtained 32.3 miles per gallon is -1.823.

(b)

The data set arranged in ascending order is:

S = {31.5 , 34.2 , 34.7 , 35.6 , 36 .0, 36.2 , 37.3 , 37.6 , 37.8 , 38.1 , 38.2 , 38.4 , 38.5 , 38.7 , 39.5 , 39.6 , 40.1 , 40.6 , 41.4 , 41.7 , 42.2 , 42.5 , 43.4 , 49.3}

The set consists of 24 values.

The first and third quartile are:

[tex]Q_{1}=[\frac{n+1}{4}]^{th}\ obs.=[\frac{24+1}{4}]^{th}\ obs.=12.5^{th}\ obs.=\frac{36.2+ 37.3}{2}=36.75\\\\Q_{3}=[\frac{3(n+1)}{4}]^{th}\ obs.=[\frac{3(24+1)}{4}]^{th}\ obs.=18.75^{th}\ obs.=\frac{40.6+41.4}{2}=41[/tex]

Thus, the value of Q₁ is 36.75 and Q₃ = 41.

(c)

Compute the inter-quartile​ range as follows:

[tex]IQR=Q_{3}-Q_{1}=41-36.75=4.25[/tex]

The inter-quartile range is 4.25.

The inter-quartile range is the amount of data that is contained within the middle 50% of a set of observations, when arranged in order. It is the distance between the first and third quartile.

(d)

Compute the values of lower and upper fences as follows:

[tex]\text{Lower fence}=Q_{1}-1.5\times IQR=36.75-(1.5\times 4.25)=30.375\approx 30.38\\\\\text{Upper fence}=Q_{3}+1.5\times IQR=41+(1.5\times 4.25)=47.375\approx 47.38[/tex]

Any values that are less than the lower fence or more than the upper fence are considered as outlier.

Consider the arranged data set.

Only one value is more than the upper fence, 47.38, i.e. 49.3.

So, yes there is one outlier, i.e. 49.3.

a ) 5^2 +1 =26

b ) 5 ^2*2=50

Answer: A

Step-by-step explanation:

Since she invested $400 in the beginning if the 1st year and we are asked to find the balance at the beginning of the third year, she earns interest only for the first two years. So, the formula will be

Amount = 400 (1 + 0.05) ^3-1

To find the balance in Josie's account at the beginning of the the third year we have to use A(3)=[tex]400*(1+0.05)^{3-1}[/tex]

It is the interest calculated on the initial principal amount and the accumulated interest. The formula to calculate the sum after compound interest is

Sum= [tex]P(1+r/m)^{tm}[/tex] where P=principal, r= rate of interest, m= number of times compounded in a year, t=time

At the beginning of year 1, Josie invests $400 at an annual compound interest at the rate of 5%,then the amount at the beginning of year 3 is calculated as:

The amount in beginning of 1 year=$400

The amount at the end of the year 1=400+400*0.05=400(1+0.05)

The amount at the end of year 2=400(1+0.05)+400(1+0.05)*0.05

=[tex]400(1+0.05)^{2}[/tex]

=[tex]400(1+0.05)^{3-1}[/tex]

Hence the option A is correct which is to be used to calculate the amount in Josie's account at the beginning of year 3.

The formula for surface area of a rectangular prism is;

Surface Area = 2(wl) + 2(lh) + 2(hw) where w is the width, l is the length and h is the height.

SA = 2(2 * 17)m² + 2(17 * 3)m² + 2(3 * 2)m²

     = 2(34)m² + 2(51)m² + 2(6)m²

Scale factor of the image = [tex]\frac{\text{One side of the triangle FED}}{\text{Corresponding side of the triangleABC}}[/tex]

                                          = [tex]\frac{\text{DF}}{\text{AC}}[/tex]

                                          = [tex]\frac{3}{6}[/tex]

                                          = [tex]\frac{1}{2}[/tex]

Coordinates of point C → (-2, 2)

Coordinates of the corresponding point C' after dilation with a scale factor [tex]\frac{1}{2}[/tex],

C(-2, 2) → C'(-1, 1)

Coordinates of point C' after reflection across y-axis,

C'(-1, 1) → C"(1, 1)

Followed by the translation of 2 units downwards,

C"(1, 1) → D[1, (1 - 2)]

          → D(1, -1)

From the graph we get the same coordinates of point D as (1, -1).

Therefore, ΔABC was dilated by a scale factor of [tex]\frac{1}{2}[/tex], reflected across the y-axis and moved through the translation of 2 units downwards.

Answer:

x = 4, y = 2√21, z = 10

Step-by-step explanation:

Since all sides of a rhombus are congruent, z = SR = 10. Since the diagonals of a rhombus bisect each other, x = PO = 4. Using Pythagorean Theorem (look at ΔPSO, we know that PS = 10 and PO = 4), y = 2√21.

Answer:

The result is 150 + 1.5d

Step-by-step explanation:

We want to translate the wordings into algebraic expression.

Firstly, we increase 120 by d%

d% = d/100

So increasing 120 by d % means;

120 + (d/100 * 120)

= 120 + 1.2d

Then increase this by 25%

= (120 + 1.2d) + 25/100(120 + 1.2d)

= 120 + 1.2d + (120+1.2d)/4

= 120 + 1.2d + 30 + 0.3d

= 120 + 30 + 1.2d + 0.3d

= 150 + 1.5d

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Plug in the points:

[tex]m= \frac{10 - 0}{0 - (-2)}[/tex]

Simplify:

[tex]m= \frac{10}{2}[/tex]

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.

Answer:

y=5x+10

Step-by-step explanation:

The base form of the equation is y=mx+b

B is always the y intercept so we can plug that in

y=mx+10

Then we can fine the slope by using the gradient formula

Change in y over change in x

The two points are (-2, 0) and (0, 10)

The result is 10/2 which can be simplified to 5

Answer:

adult = £7 and child = £2

Step-by-step explanation:

let a represent adult ticket and c child ticket, then

2a + 3c = 20 → (1)

a + 4c = 15 → (2)

Multiply (2) by - 2 and add to (1) to eliminate a

- 2a - 8c = - 30 → (3)

Add (1) and (3) term by term

- 5c = - 10 ( divide both sides by - 5 )

c = 2

Substitute c = 2 into either of the 2 equations and solve for a

Substituting into (1)

2a + 3(2) = 20

2a + 6 = 20 ( subtract 6 from both sides )

2a = 14 ( divide both sides by 2 )

a = 7

Cost of adult ticket is £7 and child ticket is £2

Answer:

Probability that the two socks picked by Natalie are of the same colours = (17/32) = 0.53125

Step-by-step explanation:

Complete Question

Natalie has 8 socks in a drawer.

5 of the socks are black.

3 of the socks are white.

Natalie takes out a sock at random, writes down its colour and puts it back into

the drawer. Then Natalie takes out a second sock, at random, and writes down its colour.

Work out the probability that the two socks are of the same colour.​

Solution

This is a probability that involves replacement.

Probability of an event is given as the number of elements in the event divided by the total number of elements in the sample space.

If the event that a black socks is picked = P(B)

Then, the event that a white socks is picked = P(W)

P(B) = n(B) ÷ n(S)

n(B) = 5

n(S) = 8

P(B) = (5/8)

P(W) = n(W) ÷ n(S) = (3/8)

Probability that the two socks picked by Natalie are of the same colours = (Probability that the two socks picked are black) + (Probability that the two socks picked by Natalie are white)

Probability that the two socks picked are black = (5/8) × (5/8) (since the socks are picked and replaced, the probability stays the same)

= (25/64)

Probability that the two socks picked by Natalie are white = (3/8) × (3/8) = (9/64)

Probability that the two socks picked by Natalie are of the same colours

= (25/64) + (9/64)

= (34/64)

= (17/32) = 0.53125
