Answer:

4. 300    5. 7     6.  2

Step-by-step explanation:

In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:

[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]

We would then cross multiply in order to find the value of x. Like this:

60 × 5 = 300

1 × x = 1x

300 = 1x

300 = x

So now we know that x is 300.

We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:

[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]

8 × x = 8x

2 × 28 = 56

8x = 56

÷8    ÷8

x = 7

We now know that x is 7.

Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

a race car is driving under the caution flag at 440 feet per second begins to accelerate at a constant rate after the warning flag. the distance traveled since the warning flag in feet is characterized by 30t^2+440t, where t is the time in seconds after the car starts accelerating again. How long will the car take to travel 150 feet?

Answers

Answer: [tex]\frac{1}{3}\ s[/tex]

Step-by-step explanation:

Given

Distance traveled is [tex]s=30t^2+440t[/tex]

for s=150 ft

[tex]\Rightarrow 30t^2+440t=150[/tex]

[tex]\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s[/tex]

Angela wants to use a one-sample zzz interval to estimate what proportion of employees at her large corporation are satisfied with their benefits. She plans on using a confidence level of 90\%90%90, percent, and she wants her margin of error to be no more than \pm 5\%±5%plus minus, 5, percent.

Answers

Answer:

Step-by-step explanation:

It's 271 on Khan Academy

The sample space size that Angela wants to use for the employees who are satisfied with their benefits is. 271

What is margin of error?

In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples. Less reliance on survey or poll results is indicated by higher statistical margins of error.

Given that,

[tex]\^p[/tex] = 0.5

1 - [tex]\^p[/tex]  = 1 - 0.5= 0.5

margin of error = E = 5% = 0.05

At 90% confidence level

= 1 - 0.90 = 0.10

0.10/2 =0.05

Z/2 = 1.645 ( Using z table )

Sample size = n = (Z/2 / E)² x   (1 - [tex]\^p[/tex])²

= (1.645 / 0.05)² * 0.5 x 0.5

=270.6

Sample size = 271

The required sample size is 271.

Solve the system of linear equations by elimination -x+y=4;x+3y=4

Answers

Answer:

the solution is (-8, 4)

Step-by-step explanation:

Let's use the addition/subtraction method here to eliminate one variable:

-x+y=4

x+3y=4

Combining these two equations results in

4y = 8, so that y = 2.  Substituting y = 2 into the second equation, we get:

x + 3(2) = 4, or x = -2.

Then the solution is (-8, 4)

A two month membership costs $125, which means Jim will pay $125 every two months he is a member at the gym. So instead of multiplying $125 by 8, we multiply it by 4 since he only has to pay every 2 months.
125•4= 500
