Answers

Answer 1

Answer:

How many integers greater than 30 and less than 40 are each the product of two distinct prime factors. The Answer is D

Answer 2

The answer is option E 5

What are prime numbers?

The numbers which are only divisible by 1 and the number itself.

What is prime factorisation?

Splitting the numbers into prime numbers, such that their product result the number itself.

First eliminate the prime numbers, 31,37

Remaining: 32,33,34,35,36,38,39

32=2x2x2x2x2

33=3x11

34=17x2

35=3x7

36=2x2x3x3

38=19x2

39=13x3

so, 33,34, 35,38,39

Therefore, 5 nnumbers between 30 and 40 are the product of two prime no.s

Answer:

C. Sphere

Volume:

V = 4/3πr³ = 4/3*9³π = 972π cm³

Surface area:

A = 4πr² = 4*9²π = 324π cm²

B. Cylinder

Volume:

V = πr²h = 3²*9π = 81π in³

Surface area:

A=2πrh + 2πr² = 2π(3*9+3²) = 2π(36) = 72π in²

A. Right Cone

Volume:

V = 1/3πr²h = 1/3π*5²*21 = 175π cm³

Surface area:

A=πr(r+√(h²+r²)) = 5π(5 + √(21²+5²)) = 5(26.58)π ≈ 133π cm²

A model rocket is launched directly upward at a speed of 15 meters per second from a height of 10 meters. The function f(t)=−4.9t2+15t+10, models the relationship between the height of the rocket and the time after launch, t, in seconds. When, in seconds after launch, will the rocket reach its highest point? Round to two decimal places.

Answers

Answer:

Step-by-step explanation:

To find the highest point we use t = -b/2a (because that's the equation used to find the maximum of the function which is the maximum height the rocket reaches before heading back down ( aka highest point of the parabola at the turning point)

f(t)  = -4.9t^2 +15 +10

A = -4.9

B  = 15

C=10

Plug it in

-15/2(-4.9)   = 1.53 seconds

(In case you get confused 15 turns negative because b in the equation has a - symbol in front. If you had -15 as B you would put -(-15) making it positive)

Hope this is helpful

1.53seconds after launch, will the rocket reach its highest point.

What is height?

In mathematics, height is defined as the vertical distance from the top of an object to the bottom. Sometimes it is labeled as "height".

The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry.

Height is a way of measuring someone or something from the bottom to the top or from the head to the feet. In other words, height indicates how tall someone or something is. We can compare how tall we will be when we grow up. We often compare the average height of men and women in different countries.

Given:

f(t)=−4.9t2+15t+10

The vertex is the highest point of the function

when t= [tex]\frac{-b}{2a}[/tex]

          =[tex]\frac{-15}{2(-4.9)}[/tex]

          ≈ 1.53

f(t) is the maximum value

1.53seconds after launch, will the rocket reach its highest point.

Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef y=what. ​

Answers

Answer:

88

Step-by-step explanation:

The total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.

What is the total cost?

Total cost or the final cost is the summation of all the cost spend while buying any good or taking any service.

Cami buys 4 pounds of ground beef for $22.  The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef.

In this problem, the total cost y has to be found out.​ As the price of one pound of ground beef is $22 and there is total 4 pounds of ground beef, Cami bought.

Thus, the total cost is,

[tex]y=22\times44\\y=88[/tex]

Thus, the total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.

What is Central Limit Theorem?

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean  and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean  and standard deviation .

here, we have,

Before testing the hypothesis, we need to understand the central limit theorem and subtraction of normal variables.

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

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean  and standard deviation

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

From a random sample of 35 customers at Store M, the average amount spent was $300 with standard deviation $40.

This means that , μ_m = 6.761

From a random sample of 40 customers at Store V, the average amount spent was $290 with standard deviation $35.

This means that , μ_v = 5.534

Assuming a null hypothesis of no difference in population means

At the null hypothesis, we test that there is no difference, that is, the subtraction of the means is 0. So

H₀ = 0

At the alternate hypothesis, we test if there is difference, that is, the subtraction of the means is different of 0. So

H₁ ≠ 0

The test statistic is:

t = X - μ / s

In which X is the sample mean,  is the value tested at the null hypothesis, and s is the standard error.

0 is tested at the null hypothesis:

This means that μ= 0

From the samples:

X = 10

s = 8.737

The test statistic is t = 1.14.

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
10

Can somebody please help me

Answers

Answer:

Area = 74.1 square units

Step-by-step explanation:

Area of the composite figure = Area of the rectangle + Area of the semicircle

Area o the rectangle = Length × Width

                                   = 10 × 6

                                   = 60 square units

Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Here, r = radius of the semicircle

For the semicircle with radius = [tex]\frac{6}{2}[/tex] = 3 units

Area = [tex]\frac{1}{2}\pi (3)^{2}[/tex]

        = 4.5π

        = 14.14 units²

Total area of the composite figure = 60 + 14.14

                                                          = 74.14 square units                                                                                              ≈ 74.1 square units
