Answer:

A.  The median height of the sample must be between 59 and 63 inches.

B. Another random sample of 20 students is likely to have a mean between 57 and 65 inches.

E.  Elena would be more likely to get an accurate estimate of the mean height of the population  by sampling 40 people instead of sampling 20 people.

Step-by-step explanation:

The mean absolute deviation shows the variation in a given data set. It can be determined by calculating the mean of the absolute value of the initial mean and each data set. It describes how spread out the data set are.

With respect to Elena's sampling, the mean absolute deviation is 2. This shows that there is little variation among the data set.

The estimate becomes more accurate if she increase the sample size. Thus options A, B and E are appropriate.

Answer:

  37/45 ≈ 0.822

Step-by-step explanation:

The formula for an exponential relation is ...

  y = a·b^x

This question is asking for the value of b. It can be found by substituting the given values of x and y, and taking the ratio of the resulting equations.

  90 = a·b^15

  74 = a·b^16

Dividing the second equation by the first, we have ...

  74/90 = (a·b^16)/(a·b^15)

  74/90 = b

The decay factor is 74/90 = 37/45 ≈ 0.822

Answer:

37/45=0.822 this is my answer

Answer:

D

Step-by-step explanation:

I believe it's d. it looks closest to the values provided.

Answer:

in triangle of 35 degree,

other angle = (35+90)

that is 125.

therefore angles is 180-125= 55 degrees.

for the upper triangle,

same thing.

180-(32+90)=180-122=58 degrees

The expected value of the raffle will be $1000 and the money obtained from selling tickets will be(4x400=$1600).

Step-by-step explanation:

First prize: $300

Second prize: 200x2=$400

3x100=$300

300+400+300

=$1000

Plz mark as brainliest

The expected value of the raffle will be $1000 and the money obtained from selling tickets would be equal to $1600.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

400 raffle tickets were sold for $4 each.

The one first prize winner will receive $300, and two people will each receive a second prize of $200.

There will be three $100 winners.

First prize = $300

Second prize = 200 x 2

=$400

So, the expected gross​ winnings:

3x100=$300

300+400+300

=$1000

Answer:

B

Step-by-step explanation:

it is important to note that 40/8 = 5.

A real number is one that can be found on the number line, and 5 can be.

A rational number can be made by dividing two integers (40 by 8 in this case).

5 is a whole number since it does not have a decimal/fractional part

an integer is a whole number which is positive/negative (5 is positive in this case)

Answer:

x = 27

Step-by-step explanation:

Using ratio:

[tex] \frac{10}{14} = \frac{x + 8}{2x - 5 } \\ 10(2x - 5) = 14(x + 8) \\ 20x - 50 = 14x + 112 \\ 20x - 14x = 112 + 50 \\ 6x = 162 \\ \frac{6x}{6} = \frac{162}{6} = > x = 27.[/tex]

Answer:

3(2g + 3)

Step-by-step explanation:

We start out with the expression (2g + 2) - (-4g - 7).

Firstly, let's distribute the negative:

(2g + 2) - (-4g - 7)

2g + 2 + 4g + 7

Now, combine like terms:

2g + 4g + 7 + 2

6g + 9

The GCF stands for "Greatest Common Factor." In this case, we have to find the GCF between 6 and 9. What is the GCF of 6 and 9? It would be 3. So,

6g + 9

3(2g + 3)

Answer:

-40

Step-by-step explanation:

You can replace the values of x with 5 and the values of y with (-2).

10 + 5xy = 10 + 5 × 5 × (-2)

              = 10 + 5 × (-10)

              = 10 + (-50)

              = -40

Answer:

Step-by-step explanation:

10+5xy

[By putting the value of x = 5 and y = -2 ]

= 10 + 5 × 5 × (-2)

= 10 - 50

= -40 (Ans)

Answer:

B. negative infinity < x < positive infinity

Step-by-step explanation:

When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for all exponential functions, including this one.

Answer:

The total value of the liquid in the container is about $41,866,666.67.

Step-by-step explanation:

A spherical container has a diameter of 100 centimeters.

It is filled with a liquid that costs $80 per cubic centimeter.

And we want to determine the total value of the liquid in the container.

We can start by finding the volume of the container.

Since the container has a diameter of 100 centimeters, its radius if 50 centimeters.

The volume of a sphere is given by:

[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]

Substitute. We will also use 3.14 for π. So:

[tex]\displaystyle =\frac{4}{3}(3.14)(50)^3=523333.33...\text{ cm}^3[/tex]

(Try not to round intermediate values.)

Since each cubic centimeter costs $80, we will multiply the total volume by the cost per cubic centimeter to find the total value. Thus, the total value is:

[tex](523333.\overline{3})(80)\approx \$41, 866, 666.67[/tex]

The total value of the liquid in the container is about $41,866,666.67.

Answer:

∠RPQ = 53°

Step-by-step explanation:

∠SPR and ∠RPQ are complementary, meaning that they add up to 90°. So,

∠SPR + ∠RPQ = 90°

We know that ∠SPR = 37°, so

37° + ∠RPQ = 90°

∠RPQ = 90° - 37°

∠RPQ = 53°
