Answer/Step-by-step explanation:

Ok so x,y. is the first thing you need to know A. 1, -5 = X, -Y.

the number from the x grid goes before the y see the arrows seperating the squares the vertical line is the X any numbers coming off of x go before y ok, x, y.

See the -5, -5 on the bottom right square both of those are negative and since E. is negative (-2, -2) it gets placed in the negative bottom right square ok.

now you see how for some squares there is only 1 number for them well the number on the other side where there is no number is the number. In the top right square there is only 5 on the y line meaning that if u look beyond that and where the other number suppose to be the -5 is there so -5 is the answer for that ok.

(The 0 in the middle is called the "Origin")

Hope this helps! I didn't exactly answer because there's no way to answer without downloading or submitting an image but it wont let me download it for some reason.

Top right square = -5, 5.

C. goes into the top right square

Top left = 5, 5.

B. goes into the top left square

Bottom right square = -5, -5.

E. gets placed in the bottom right square

Bottom left square = 5, -5.

D. gets placed in the bottom left square

A. gets placed in the bottom left square

The area (A) of a trapezoid is calculated as follows:

A = 1/2 * sum of the parallel sides * height

In this case:

A = 1/2 * (3.4 + 1.1) * 2 = 4.5 cm^2.

Answer:

4 3/4

Step-by-step explanation:

Answer:

Height = 4 cm and slant height = 5 cm

Step-by-step explanation:

Given that,

The surface area of the cone, A = 75.4 cm²

Radius, r = 3 cm

The surface area of the cone is given by the formula as follows :

[tex]A=\pi r^2+\pi rl[/tex]

Put all the values,

[tex]75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm[/tex]

Also,

[tex]l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm[/tex]

Hence, the height of the cone is 4 cm and the slant height is 5 cm.

Answer:

0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Standard deviation of 86 minutes with a mean life of 505 minutes.

This means that [tex]\sigma = 86, \mu = 505[/tex]

Sample of 120:

This means that [tex]n = 120, s = \frac{86}{\sqrt{120}}[/tex]

What is the probability that the mean battery life would be greater than 523.8 minutes?

This is 1 subtracted by the p-value of Z when X = 523.8. So

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

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{523.8 - 505}{\frac{86}{\sqrt{120}}}[/tex]

[tex]Z = 2.39[/tex]

[tex]Z = 2.39[/tex] has a p-value of 0.9918.

1 - 0.9918 = 0.0082

0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes

Step-by-step explanation:

#27). 6k² = 48

k = √8 = 2√2

x = [tex]\frac{8}{2\sqrt{2} }[/tex] = 2√2 cm

y = [tex]\frac{12}{2\sqrt{2} }[/tex] = 3√2 cm

#29). 16k² = 48

k = √3

x = [tex]\frac{8}{\sqrt{3} }[/tex] = [tex]\frac{8\sqrt{3} }{3}[/tex] cm

Answer:

h ≤ 45

Step-by-step explanation:

The maximum height is 45 feets

Let the height of the object = h

Hence, the sentence means that the height, h of the object cannot be beyond 45 feets ;

This means the height can be any number of feets less than or equal to 45 feets

Hence, h ≤ 45

Answer:

9 yrs ago

Step-by-step explanation:

(50-x)(20-x) = 451

x^2-70x + 1000 = 451

x^2-70x + 549 = 0

(x-9)(x-61) = 0

x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)

Hi there!

[tex]\large\boxed{\text{ P = 31ft, A = 35ft}^2}[/tex]

Perimeter: Add up all the side lengths.

14 + 10 + 7 = 31 ft.

Area: Use the following formula:

A = 1/2(bh) where:

b = bass

h = height

Thus:

A = 1/2(10 · 7) = 35 ft²

Answer:

(0, 0), (0, 3), (2, 3), and (5, 0)

Step-by-step explanation:

The constraints of the problem are:

x + y ≤ 5

y ≤ 3

x ≥ 0

y ≥ 0

Then:

Using the second and fourth inequalities we can write:

0 ≤ y ≤ 3

Knowing that the minimum value of y is 0, then if we replace that in the first equation we get:

x + 0 ≤ 5

x ≤ 5

While for the maximum value of y, y = 3, this inequality becomes:

x + 3  ≤ 5

x ≤ 2

Now, the vertexes are the points where both variables take one of their extremes.

Then, we have a vertex at (0, 0) because we have:

x ≥ 0

y ≥ 0

So this is the vertex when both x and y take the minimum value.

When y takes the maximum value y = 3, and x takes the minimum value x = 0, we have the vertex:

(0, 3)

When y takes the maximum value, y = 3, and x takes the maximum value, x = 2, we have the vertex:

(2, 3)

When y takes the minimum value, y = 0, and x takes the maximum value, x = 5, we have the vertex:

(5, 0)

Then the four vertexes are:

(0, 0), (0, 3), (2, 3), and (5, 0)

The simplification of c^3d^4/c^2d is cd^3.

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.

For the given situation,

The expression is c^3d^4/c^2d.

The simplification is as

⇒ [tex]\frac{c^{3}d^{4} }{c^{2}d }[/tex]

⇒ [tex]\frac{(c^{2})( c)(d^{3} )(d)}{c^{2} d}[/tex]

⇒ [tex]cd^{3}[/tex]

Hence we can conclude that the simplification of c^3d^4/c^2d is cd^3.

Answer:

m<G = 59°

Step-by-step explanation:

Recall: the angle formed outside a circle when 2 secants intercept is equal to half of the difference of the intercepted arcs

m<G = ½(arc TE - arc HF)

m<G = ½(175 - 57)

m<G = ½(118)

m<G = 59°

The number of adult tickets sold will be 275.

Given is that a total of 494 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer student tickets sold than adult tickets.

Assume that the number of adult tickets sold are [x] and the student tickets sold are [y]. Then -

x + y = 494

y = x - 56

So, we can write the equation as -

x + x - 56 = 494

2x = 550

x = 275

Then, we can find [y] as -

y = 275 - 56 = 219

y = 219

Therefore, the number of adult tickets sold will be 275.
