THE ANSWER IS B

Answer:

2x+76°=180°[by co interior angle]

2x=180°-76°

2x=104°

x=104°/2

x=52

Answer:

B 9.72

Step-by-step explanation:

If we imagine 7.48 is 100% Then we can use multiply and divide to find 30%. It goes like this. x/7.48 = 30/100. Where x is the unknown. Take 30 times 7.48 which is 224.4 then divide by 100 we get 2.24 dollars. Added to 7.48 we get 9.72

Step-by-step explanation: yeah

Answer:

B

Step-by-step explanation:

There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.

For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.

Top left = (-3,4)

Bottom left = (-2, -4)

Top right = (3,4)

Bottom right = (1,-4)

Answer:

y=2x-3

Step-by-step explanation:

Y-intercept can be read off the graph.

Slope can be determined using the formula:

y2-y1 divided by x2-x1 (Substitute co-ordinates)

Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

Where m is the slope and b is the y intercept

Slope is rise over run, the line is up 2 over 1

And the point of the line where it meets the y axis is -3. so b is -3

Answer:

Unitary cost= $15.705

Step-by-step explanation:

Giving the following information:

Their bill totaled $52.35. They left the server a 20% tip.

First, we need to calculate the total cost of the meal:

Total cost= 52.35*1.2= $62.82

Now, we can split it into 4 equal parts:

Unitary cost= 62.82 / 4

Unitary cost= $15.705

Answer:

7m² - 11m - 2

Step-by-step explanation:

(4m² - m + 2) - (-3m² + 10m + 4)

= (4m² - (-3m²)) + (-m - 10m) + (2 - 4)

= (4m² + 3m²) + (-11m) + (-2)

= 7m² - 11m - 2

Answer:

88m

Step-by-step explanation:

Hey There!

Essentially the question is asking for the circumference of the circular garden

The first thing that we want to do is find the formula of for the circumference

[tex]C=2r\pi[/tex]

14x2=28

they said to use [tex]\frac{22}{7}[/tex] for pie

so we do

[tex]\frac{22}{7} x28=88[/tex]

so the circumference is 88m

or the amount of fencing needed is 88m

Answer:

0.0475 = 4.75% probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag.

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 zscore 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 pvalue, 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.

Single bag:

[tex]\mu = 12.5, \sigma = 1.5[/tex]

Sample of 25 bags:

[tex]n = 25, s = \frac{1.5}{\sqrt{25}} = 0.3[/tex]

What is the probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag?

This is 1 subtracted by the pvalue of Z when X = 13. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{13 - 12.5}{0.3}[/tex]

[tex]Z = 1.67[/tex]

[tex]Z = 1.67[/tex] has a pvalue of 0.9525

1 - 0.9525 = 0.0475

0.0475 = 4.75% probability of randomly picking a sample of n =25, 1-pound bags that average more than M = 13 shrimp per bag.

top triangles are is 49.5  

middle triangle is 67.5

bottom triangle is 150

add everything up

Answer:

B.) 978 square inches

Step-by-step explanation:

L=30

W=24

30·24=720

Area formula for a triangle: BH1/2

1st & 2nd Triangles

B=9

H=12

(9)(12)(1/2)=54

(9)(12)(1/2)=54

3rd Triangle: (15)(20)(1/2)=150

Add all the areas of the shapes: 54+54+720+150=978

Correct me if I'm wrong

Answer:

D. (3x^2-3x+27)^1/3

Step-by-step explanation:

dy/dx=2x−1/y^2

Cross multiply to get Y's and X's on different sides.

(y^2)dy = (2x-1)dx

Take the integral of each side

∫(y^2)dy = ∫(2x-1)dx

y^3/3 = 2x^2/2 - x + C

Multiply both sides by 3

y^3 = 3x^2 - 3x + C

Plug in (0,3) and solve for C

27 = 0 - 0 + C

C = 27

Plug in C to the equation

y^3 = 3x^2-3x+27

Cube root both sides to get just y

y = √(3x^2-3x+27)

y = (3x^2-3x+27)^1/3

D.

The particular solution of the equation will be "[tex](3x^2-3x+27)^\frac{1}{3}[/tex]".

According to the question,

→    [tex]\frac{dy}{dx}[/tex] = [tex]\frac{2x-1}{y^2}[/tex]

By applying cross-multiplication,

(y²)dy = (2x - 1)dx

By integrating both sides, we get

→ ∫(y²) dy = ∫(2x - 1) dx

           [tex]\frac{y^3}{3}[/tex] = [tex]\frac{2x^2}{2}[/tex] - x + C

By multiplying "3" both sides, we get

           y³ = 3x² - 3x + c

By substituting "(0,3)" in above equation,

          27 = 0 - 0 + C

            C = 27

By substituting value of C in the above equation,

         y³ = 3x² - 3x + 27

By cubing both sides,

y = √(3x²-3x+27)

  = [tex](3x^2-3x+27)^\frac{1}{3}[/tex]        

Thus the above answer i.e., "Option D" is correct.

Answer:

t= 9.49 years which can be estimated to 9 years

Step-by-step explanation:

Given the formula l = prt,

Where P is the principal=$245

r is the interest rate.=3%,

l = interest earned=$69.80

l = prt

Therefore time, t= I/ pr

t= 69.80/ 245 x 3%

t=69.80/ 245 x 0.03

t= 9.49 years which can be estimated to 9 years
