Answer:

7. 48000 ounces

8. 1. 25 pound

9. 1/16

10. ounces

11. weight

12. pounds

Step-by-step explanation:

7) A hippopotamus weighs 1. 5 tons. What is its weighs in ounces

answer

All you need to do is to use proportion to solve this problem

Let x represent the weight of the hippopotamus in ounces

1 ton = 32 000 ounces

1. 5tons= x

cross multiply to get the value of x

x = 32000 × 1. 5

x = 48 000 ounces

Therefore the weight of the hippopotamus in ounces is 48 000

9. What fractional part of a pound is an ounce

answer

1 pound = 16 ounces

which implies

1 ounce = 1/16 pounds

Therefore the fractional part of a pound that is an ounce is 1/16

10. Since the weight of a paper is very light, ounce woud be the most appropriate customary unit to measure it

11. Weight is the measure of how heavy an object is.

12. The weight of a bag of a flour is not upto a ton, therefore pounds would be the appropriate customary unit to measure the weight of a flour.

Identify two composite numbers that each have 8 as a factor.
Dima020 [189]
<span>A composite number, we remember, is a whole number (no decimals or fractions) that can evenly divide (again, into no fractions or decimals) into two numbers other than itself and 1 (sort of the opposite of a prime number). So, 8 needs to be one of the two numbers. Pick another number--any whole number--and multiply it by 8. The result will be your composite number. Two examples: 8 times 6 equals 48. This works as 48 divided by 8 equals 6, both of which are whole numbers other than 48. Another is 72, the product of 8 times 9.</span>

9 less than the sum of x and 5
saw5 [17]

Answer:

Given the statement:

9 less than the sum of x and 5

"Sum of x and 5" means x+5

"\text{less than}" means subtract

then;

the statement 9 less than the sum of x and 5 becomes;

⇒(x+5) - 9

⇒x+5-9 = x-4

Therefore, the expression for the given statement is (x+5) - 9

The p-value for a one-sided test of the population proportion is 0.0513. Which of
uysha [10]

Using the equation of the test statistic, it is found that with an increased sample size, the test statistic would decrease and the p-value would increase.

<h3>How to find the p-value of a test?</h3>

It depends on the test statistic z, as follows.

  • For a left-tailed test, it is the area under the normal curve to the left of z, which is the <u>p-value of z</u>.
  • For a right-tailed test, it is the area under the normal curve to the right of z, which is <u>1 subtracted by the p-value of z</u>.
  • For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is <u>2 multiplied by 1 subtracted by the p-value of z</u>.

In all cases, a higher test statistic leads to a lower p-value, and vice-versa.

<h3>What is the equation for the test statistic?</h3>

The equation is given by:

t = \frac{\overline{X} - \mu}{\frac{s}{\sqrt{n}}}

The parameters are:

  • \overline{X} is the sample mean.
  • \mu is the tested value.
  • s is the standard deviation.
  • n is the sample size.

From this, it is taken that if the sample size was increased with all other parameters remaining the same, the test statistic would decrease,  and the p-value would increase.

Someone help please
Mrac [35]
Use ax^2 + bx + c = 0

ac = -8
b = 2

The factors are 4 and -2.
Plug them into the equation:

x^2 + 4x - 2x - 8

Then factorise it:

x ( x + 4) - 2 (x + 4)

so m = 4

(x + 4)^2
