Answer:

192 in³

Step-by-step explanation:

A trapezoidal prism is a three dimensional solid that has two similar trapezoids at its top and base.The two similar trapezoids are connected by four rectangles connecting the corresponding sides of the two bases.

The Area of the trapezoid at the top or base = 1/2 (a + b)h

Where a and b are the lengths =  7 inches and 5 inches and the height (h) = 4 inches.

Therefore Area of the trapezoid at the top or base = 1/2 (a + b)h = 1/2(7 + 5)4 = 24 in²

The volume of gift box = Area of the trapezoid at the top or base × height of gift box = 24 × 8 = 192 in³

Answer: 42/11 = 21/5.5

Step-by-step explanation:

1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.

2) Therefore, the ratio is 42/11.

3)The adjacent sides to the right angle are 21 and 5.5.

4)Therefore, the ratio is 21/5.5

Answer:

1) a30=96

2) 30(-20+96)/2

3) 1140

Step-by-step explanation:

I just did on Edg 2020

The solution is, the 30th term of the sequence a_30 = 96.

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.

The nth term of AP : a_n = a + (n – 1) × d

here, we have,

the given sequence is,

-20,-16, -12,-8,-4, ...

so, here, we have,

a = -20

d = 4

so, the 30th term of the sequence is,

a_30 = a + (30-1) d

         = -20 + 29*4

         = 96

Hence, The solution is, the 30th term of the sequence a_30 = 96.

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

Answer:

A rational number can be written as the ratio of two integers.

Step-by-step explanation:

Answer: C) H0 : μ = 250 , Ha: μ < 250

Step-by-step explanation:

The questions is incomplete. The correct question is

A restaurant advertises that its burritos weigh 250 g. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g. Let u be the mean weight of the burritos at this restaurant and ĉ be the mean weight of the burritos in the sample. Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer:

A) H0 : x = 250 , Ha : x < 250

B) H0 : x = 250 , Ha : x > 250

C) H0 : μ = 250 , Ha: μ < 250

C) H0 : μ = 250 , Ha: μ > 250

Solution:

The null hypothesis is the hypothesis that is assumed to be true. The restaurant advertises that its burritos weigh 250. This is the null hypothesis. 250 is the population mean,μ . Thus, the null hypothesis is

H0 : μ = 250

The alternative hypothesis is what the researcher expects or predicts. The consumer advocacy group tests if the mean weight is significantly lower than 250g. This is the alternative hypothesis. It is expressed as

H0 : μ < 250

Answer:

Yes, because 0.002 < 0.01

Step-by-step explanation:

Answer:

the answer is -5

Step-by-step explanation:

1. identify the ordered pairs

2. write down the slope formula

3. replace the letters with their values

4. subtract

5. divide

Step-by-step explanation:

An explanatory variable is a type of independent variable. The two terms are often used interchangeably. But there is a subtle difference between the two. When a variable is independent, it is not affected at all by any other variables. When a variable isn’t independent for certain, it’s an explanatory variable.

Let’s say you had two variables to explain weight gain: fast food and soda. Although you might think that eating fast food intake and drinking soda are independent of each other, they aren’t really. That’s because fast food places encourage you to buy a soda with your meal. And if you stop somewhere to buy a soda, there’s often a lot of fast food options like nachos or hot dogs. Although these variables aren’t completely independent of each other, they do have an effect on weight gain. They are called explanatory variables because they may offer some explanation for the weight gain.

The line between independent variables and explanatory variables is usually so unimportant that no one ever bothers. That’s unless you’re doing some advanced research involving lots of variables that can interact with each other. It can be very important in clinical research. For most cases, especially in statistics, the two terms are basically the same.

An explanatory variable is an independent variable.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given:

A variable is an explanatory variable.

A researcher-manipulated variable is an explanatory variable when it comes to an experiment.

It serves as a measurement of the change brought about in the response variable.

A predictor variable or an independent variable are terms that are frequently used to describe an explanatory variable.

Therefore, an explanatory variable is an independent variable.

#SPJ2

the equation is y=2x+30

Answer:

It should be red or green 125 times

Step-by-step explanation:

The first thing to do here is to calculate the probability of selecting a red or a green marble

Total number of marbles = 7 + 3 + 2 + 8 = 20

Probability of selecting a red marble is 7/20

Probability of selecting a green marble is 3/20

The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2

Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times

Answer:

16 sq. in

Step-by-step explanation:

I think you are asking for the area. The rectangle to the right of the dotted line has dimensions of 4 by 3, so its area is 4 * 3 = 12. We know one of the small rectangle's dimensions, 2, but we don't know the height. However, we see that the difference between the heights of the two figures is 1, and we already know the height of the larger rectangle is 3, so the height of the smaller square is 2. This makes its area 2 * 2 = 4. The total area would then be 12 + 4 = 16 sq. inches. Hope this helps!

Step-by-step explanation:

On a graph, the direction of the line with points [tex](1,7)[/tex] and [tex](10, 15)[/tex] is going up to the right.

Answer: 88 square inches

If we want to wrap the box, we need to work out its surface area - the area that will need to be covered by the giftwrap.

This box is a cuboid, so there will be six faces, with only three different areas (each face has an identical pair).

Let's say the height is 2 in, the length is 6 in and the depth 4 in.

height = 2

length = 6

depth = 4

Let's find the area of the faces that measure height x length:

2 x 6 = 12 square in

Now let's do the same thing for height x depth:

2 x 4 = 8 square in

And finally for length x depth:

6 x 4 = 24

There are two of each of these faces, so let's multiply each result by two.

12 x 2 = 24

8 x 2 = 16

24 x 2 = 48

Finally, all that's left to do is add these numbers together to find the total surface area of the cuboid.

24 + 16 + 48 = 

88 square inches

Answer:

88 square inch

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

The text of the question is incomplete. However, the likely question that can be asked may imply that; "what number of corn package did she use?"

Given that

1 package of corn = 8 cups

1 serving = 1 cup

Total individual = 11

Servings per individual = 2

If there are 2 servings per individual then 1 package of corn will serve the following number of people.

1 package of corn = 8 / 2 individuals

1 package of corn = 4 individuals

Divide both sides by 4.

1 package of corn / 4 = 4 individuals / 4

¼ package of corn = 1 individual.

Re-arrange

1 individual = ¼ package of corn.

So, this means that 11 individuals will get;

[Multiply both sides by 11]

11 * 1 individual = ¼ * 11 package of corn

11 individuals = 11/4 package of corn

11 individuals = 2.75 packages of corn.

Hence, Ron will need 2.75 packages of corn for 11 individuals
