Answer:

It is 47.5 or 47 1/2

Step-by-step explanation:

The formula for volume of a prism is base x height.

The base is the area of the rectangle at the bottom. The area of a rectangle is, of course, length times width, so 2.5 x 4=10.

So, the base is 10.

Now, the second part of the formula is height.

The height is 4.75.

Now, do the formula: Base x height : 10 x4.75

The answer is 47.5.

Answer:

To maximize the profits of the company, the subscription price should be raised to $ 22.

Step-by-step explanation:

Given that a bi-monthly sports magazine has 48,000 subscribers when it charges $ 20 for a one year subscription, and for every $ 1 increase in the yearly subscription price, the magazine assumes that it will lose 2,000 subscribers resulting in the equation below, to determine, Using the equation below, how much should the magazine sell for in order to maximize revenues, the following calculations should be performed:

f (x) = (48,000 - 2,000x) (20 + x)

X = 48,000 x 20 = 960,000

X = (48,000 - 2,000x1) x (20 + 1)

X = 46,000 x 21

X = 966,000

X = (48,000 - 2,000x2) x (20 + 2)

X = 44,000 x 22

X = 968,000

X = (48,000 - 2,000x4) x (20 + 4)

X = 40,000 x 24

X = 960,000

Therefore, to maximize the profits of the company, the subscription price should be raised to $ 22.

Answer

[tex]f(t) = 11500 * (3)^{\frac{t}{14}}[/tex]

Explanation

Given

[tex]a = 11500[/tex] -- initial

[tex]b = 3[/tex] ---- every 14 years

Required

The exponential equation

The exponential equation is:

[tex]y =ab^T[/tex]

First, calculate the yearly rate.

Triples every 14 years, implies that:

[tex]b = 3[/tex] -- the rate

[tex]T=\frac{t}{14}[/tex] ---- time

So:

[tex]y =ab^t[/tex]

[tex]y = 11500 * (3)^{\frac{t}{14}}[/tex]

Hence:

[tex]f(t) = 11500 * (3)^{\frac{t}{14}}[/tex]

Answer:

The calculated value   t = 2.5>2.326 at 0.01 level of significance

The null hypothesis is rejected at a 0.01 level of significance.

Wheaties cereal is not claimed to have an average of 3 grams of dietary fiber per serving

Step-by-step explanation:

Step(i):-

Given that the average  of dietary fiber per serving μ = 3 grams

Given that the mean of the sample x⁻ = 3.4 grams

Given that the standard deviation of the sample (S) = 0.8 grams

Level of significance = 0.01

Critical value = 2.326

Step(ii):-

Null hypothesis: H₀:  μ = 3 grams

Alternative Hypothesis: H₁: μ ≠ 3 grams

Tets statistic

               [tex]t = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

              [tex]t = \frac{3.4-3 }{\frac{0.8}{\sqrt{25} } }[/tex]

             t = 2.5

The calculated value   t = 2.5>2.326 at 0.01 level of significance

The null hypothesis is rejected at a 0.01 level of significance.

Final answer:-

Wheaties cereal is not claimed to have an average of 3 grams of dietary fiber per serving

Answer:

13) a and b,  b and c

14) a = 59°, b = 121°, c = 59°

15) a = 45°, b = 135°, c = 135°

16) a = 72°, b = 108°, c = 108°

Answer:

y < 2x + 5

Step-by-step explanation:

The format for slope intercept is y = mx + b. In this case, it is y < mx + b. Your equation is -4x + 2y < 10. First, start by adding 4x to -4x. This gets rid of that number on the left so it can just be 2y. Now, add that 4x to the right side of the equation. You are left with 2y < 4x + 10. The final step is to divide 2 from 2y. Since you are doing this step on the left side of the equation, you must now do it to the right. After also dividing 2 from 4x and 10, your final answer is y < x +5.

U got any more math questions that I can answer? I’m really bored and I have to stay busy!

Answer:

the probability is 0.0067

Step-by-step explanation:

The computation of the probability of receiving no e-mails during an hour is shown below;

Let us assume x be the number of emails received during an hour

Now the probability of receiving no e-mails is

= e^-5 × 5^0÷ 0!

= e^-5 × 1  ÷ 1

= e^-5

= 0.00674

= 0.0067

Hence, the probability is 0.0067

Answer:

50 is the answer brainliest?

Step-by-step explanation:

Answer:

5,4 km

Step-by-step explanation:

we know the area and the width.

the formula of the area of a parallelogram is

A = length x width

if we substitute the values that we know, we have

23,1 = x * 4,3

to find x we have to divide the two members by 4,3

x = 23,3/4,3 = 5,4 km

Answer:

x=10

Step-by-step explanation:

Because of the two parallel lines, the ratio between the sides must be the same.  Since the bottom is 12 to 18 (a ration of two to three) we know that x and x+5 would have the same ratio.  Logically, x would have to equal 10 so that x+5 would equal 15 and a ratio of two to three would exist there too.  If you go to solve a problem and the answer isn’t obvious, jut set up a ratio.

12/18=x/(x+5)

then cross multiply and solve

12(x+5)=18x

12x+60=18x

60=18x-12x

60=6x

10=x

Answer:

x=10

Step-by-step explanation:

You can set it up as a proportion, since the lines are parallel, the sections are proportionate to each other.

[tex]\frac{x}{12} = \frac{x+5}{18} \\18x=12(x+5)\\18x=12x+60\\6x=60\\x=10[/tex]
