Solve the inequality 3k &gt; 5k+12
Natali5045456 [20]

Alright, let's solve this problem! :)

<u>First we need to subtract 5k from both sides.</u>

3k−5k>12

<u>Then we simplify 3k - 5k to -2k.</u>

-2k > 12

<u>Now we divide both sides by -2.</u>

k < -12/2

<u>Now we simplify 12/2 to 6.  </u>

k < -6

✔️Done!

Have an amazing day!

Write an equivalent expression for 88 +16x +8 . If x=4,is the solution to both expressions the same.
Firlakuza [10]
You can find an equivalent expression for this by combining like terms.
The terms are 88, 16x, and 8.
The like terms are 88 and 8.
To combine them, add them together.
88 + 8 = 96
The equivalent expression would be 16x + 96.
This means 16x + 96 is the same as <span>88 + 16x + 8.

Since they are equivalent, that means they are equal, or the same.
So no matter what x is, they will both be equal to the same thing, so their solutions will be the same.

Answers:
Equivalent Expression: 16x + 96
Yes, both expressions will have the same solutions if x = 4.

Hope this helps!</span>

Renee wants to estimate the percentage of people who lease a car. She surveys 150 individuals and finds that 33 lease a car. Fin
Oduvanchick [21]

Answer: (0.164,\ 0.276)

Step-by-step explanation:

The confidence interval of population proportion is given by :-

\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

Given : Sample size : n=150

The proportion of individuals lease a car :hat{p}=\dfrac{33}{150}=0.22

Significance level : \alpha: 1-0.9=0.1

Critical value : z_{\alpha/2}=1.645

Then, the confidence interval of population proportion is given by :-

0.22\pm (1.645)\sqrt{\dfrac{0.22(1-0.22)}{150}}\\\\\approx0.22\pm0.056=(0.164,\ 0.276)

Hence, the confidence interval for the population proportion with a 90% confidence level= (0.164,\ 0.276)
