Answer:

x=8

Step-by-step explanation:

13=x+5

8=x

Answer:

x = 8

Step-by-step explanation:

Okay, so the top and bottom of a parallelogram are equal (or else it would be a trapezoid), so we just have to construct our cute lil algebraic expression:

x + 5 = 13

So now we have to do the inverse operations thingy:

13 - 5 = 8

So x = 8

The probability that  the pitcher will throw 4 or fewer pitches to a batter is 0.9.

The way to find the likeliness of an event is called Probability.

It is given that

Pitcher is throwing ball

The probability that he throws 4 or fewer pitches to a batter is = ?

The no. of favourable outcomes for the given condition is

P(X ≤4 ) = P(X=1) + P(X =2) + P(X=3)+P(X=4)

Total Outcomes = 15+20+40+15+20

Total outcomes = 100

Favourable outcomes = 15+20+40+15

Favourable Outcomes = 90

Probability =  Favourable Outcomes / Total Outcomes \

Probability = 90/100 = 0.9

Therefore the probability that  the pitcher will throw 4 or fewer pitches to a batter is 0.9.

Answer:

t = - 24

Step-by-step explanation:

Given t varies inversely as a then the equation relating them is

t = [tex]\frac{k}{a}[/tex] ← k is the constant of variation

To find k use the condition t = 2 when a = - 4

2 = [tex]\frac{k}{-4}[/tex] ( multiply both sides by - 4 )

- 8 = k

t = [tex]\frac{-8}{a}[/tex] ← equation of variation

When a = [tex]\frac{1}{3}[/tex] , then

t = [tex]\frac{-8}{\frac{1}{3} }[/tex] = - 24

Answer:

6:5

Step-by-step explanation:

Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.

The algae is spherical in nature

Volume of the algae =4/3 pi r³

Volume of the algae = 4/3×pi×2.5³

Volume of the algae = 62.5/3 pi

Surface area = 4pi r²

Surface area = 4pi ×2.5²

Surface area = 25pi

Taking their ratio

surface area : volume ratio

= 25pi:62.5/3 pi

= 25 × 3/62.5

= 1.2

Hence the required ratio is 12/10 which is 6:5

Answer:

x = -56

Step-by-step explanation:

0.75(x + 20) = 2 + 0.5(x - 2)

0.75x + 15 = 2 + 0.5x - 1

0.25x = -14

x = -14/0.25

Answer:

[tex]A' = (-4,4)[/tex]

[tex]B' = (2,6)[/tex]

[tex]C' = (2,0)[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]A = (-2,2)[/tex]

[tex]B= (1,3)[/tex]

[tex]C= (1,0)[/tex]

[tex]k = 2[/tex] --- scale factor

Required

The new coordinates

The new coordinate is calculated by:

[tex]New = Old * k[/tex]

So, we have:

[tex]A' = A * 2[/tex]

[tex]A' = (-2,2) * 2[/tex]

[tex]A' = (-4,4)[/tex]

[tex]B' = B * 2[/tex]

[tex]B' = (1,3) * 2[/tex]

[tex]B' = (2,6)[/tex]

[tex]C' = C * 2[/tex]

[tex]C' = (1,0) * 2[/tex]

[tex]C' = (2,0)[/tex]

Answer:

C

Step-by-step explanation:

The confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64). Then the correct option is C.

If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.

Let the sample mean given as μ and

The sample standard deviation σ, and

The sample size = n, and

Then the heights would be outside the 90% confidence interval will be

For 90% confidence interval, we have z = 1.645

⇒ μ ± z (σ/√n)

Kat is interested in getting chickens, so she can have fresh eggs.

Before she buys her chickens, she wants to find the mean number of eggs each one will lay.

She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month.

She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs.

The 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay in one month will be

⇒ μ ± z (σ/√n)

⇒ 24.8 ± 1.645 (6.9/√40)

⇒ 24.8 ± 1.84

Then the confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64).

Then the correct option is C.

Answer:

  (25/3)π

Step-by-step explanation:

A central angle of 120° is 1/3 of a circle, so the arc length will be 1/3 of the circumference:

  (1/3)(25π) = (25/3)π ≈ 26.18 . . . . units

Answer:

Circumference = 25π

Total angle made by circle = 360

Now,

120 is ⅓ of 360⁰.

⅓ × 25π = 25π/3

Hence,

Length of arc = 25π/3

Answer:

d) Yes, there is evidence that the population mean is greater than 3.5, because the entire 95% confidence interval is greater than 3.5.

Step-by-step explanation:

edge 2020

The evidence that the true mean number of hours of screen time for US adults is greater than 3.5 is there is evidence that the population mean is greater than 3.5, because 3.5 is not within the 95% confidence interval.

It is an estimate of an interval used in statistics, which contains a population parameter. This unknown population parameter is found through a sample model calculated from the collected data.

The confidence level index is directly linked to the margin of error. In that case, there is evidence that the population mean is greater than 3.5, because 3.5 is not within the 95% confidence interval.

Answer:

The 41st term of the given series is 324

Step-by-step explanation:

a= 4

a2= 12

d= a2-a

d= 12-4 = 8

now, we have to find 41 term that is a41

a41 = a+ 40d

a41= 4+ 40× 8

a41= 4+ 320

= 324

therefore the 41st term is 324

Answer:

324

Step-by-step explanation:

The sequence observed appears to be an arithmetic sequence. The formula for an arithmetic sequence is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, n is the term position, and d is the common difference. Let's write down what we know.

n = 41

a1 = 4

d = 8

So, let's plug our values into the equation and solve.

an = 4 + (41 - 1)8

an = 4 + (40)8

an = 4 + 320

an = 324
