Cost of 3 packets = \frac{2m}{5}*3=\frac{6m}{5}

Change receive by her = 10 -\frac{6m}{5}\\\\

                                      =\frac{10*5}{1*5}-\frac{6m}{5}\\\\=\frac{50}{5}-\frac{6m}{5}\\\\=\frac{50-6m}{5}

Answer:

V ≈ 8.67x10^7 ft^3

Step-by-step explanation:

We know that the volume of a pyramid is V= (lwh)/3

Since it is a square pyramid, it means that the length and the width are the same:

Length=755.9 feet

Width=755.9 feet

Height=455.4 feet

So, the volume is :

V = [(755.9)(755.9)(455.4)]/3

V = 86736214.158 ft^3

V ≈ 8.67x10^7 ft^3

Hope this helps!

What is the answer? <br>x+y=15 <br>-2x+5y=-2​
zavuch27 [327]
Multiply the first equation by 2

2x + 2y =30

now we’ll add the second equation to the first equation

2x + 2y =30
-2x+5y= -2

7y=28

divide by 7

y=4

now plug y back into the first equation

x + 4 = 15

subtract 4

x=11

Which of the following illustrates the truth value of the given conditional statement?
Blababa [14]

Answer:

  • <u><em>Option A. F  T  →  F</em></u>

Explanation:

A conditional is represented by:

  • p → q

Where p is called the antecedent, and q is the consequent.

Thus, a conditional states that if the antecedent is true, its consequent is also true; also, if the consequent is false, then the antecedent must be false.

On the other hand, if the antecedent is true, the consequent can be either true or false.

<u>1. State the antecedent of the conditional and is truth value</u>

  • Antecedent: 6 > 10
  • Truth value: False, because 6 is not greater than 10.

<u>2. State the consequent of the conditional and its truh value</u>

  • 8 • 3 = 24
  • Truth value: True, because 8 times 3 is 24.

<u>3. Truth value of the conditional</u>

Hence, the truth value of the conditional is:

  • False      Truth        →     Truth, or
  • F   T   →   T

Which is the option A.

Suppose a researcher is testing to see if a basketball player can make free throws at a rate higher than the NBA average of 75%.
stich3 [128]

Answer: A. Repeated results if the player makes 75% of his shots in the long run.

Step-by-step explanation:

The null distribution is always the opposite of the alternative distribution which in most cases represents the claim or hypothesis which is to be tested or performed. In the scenario given, the challenge is to show that a basketball player has an average higher than that of the NBA. NBA average stands at 75%. The alternative hypothesis is the claim, which is ;

H1 : μ > 75%

THE null is thus :

H0 : μ = 75% ; which means that repeated result of the player will yields an average of 75%
