Answer:

No.

Explanation:

If you did the order of operations, you would get:

A researcher believes that 12% of a simple random sample of adults will be able to identify a Toyota Scion by brand and model na

DochEvi [55]

Answer: 650

Step-by-step explanation:

When prior estimate of population proportion is known , then the formula to find the required sample size is given by :-

$n=p(1-p)(\dfrac{z^*}{E})^2$

, where p= population proportion

E= margin of error

z* = Critical value.

Let p be the proportion of adults able to identify a Toyota Scion by brand and model name.

As per given , we have

p = 12%= 0.12

E= 2.5%=0.025

Critical value for 95% confidence interval : z* = 1.960 [By z-table ]

Then, the required sample size = $n=(0.12)(1-(0.12))(\dfrac{1.96}{0.025})^2$

$n=(0.1056)(78.4)^2$

$n=(0.1056)(6146.56)$

$n=649.076736\approx650$

Thus , the required sample size = 650

What’s the answer too this problem I can’t solve?

emmasim [6.3K]

I'm using PEDMAS.

Multiplication first.

2 • 4 = 8

Subtraction.

20 - 4 = 16

16 + 8 = 24

Please let me know if you spot any errors (especially the fraction operation)

Which is true regarding the system of equations?<br><br> x minus 4 y = 1. 5 x minus 20 y = 4.

goldfiish [28.3K]

Answer:

No solution

Step-by-step explanation:

x - 4y = 1 --> (1)

5x - 20y = 4 --> (2)

y = (¼)x - ¼ --> (1)

y = (¼)x - ⅕ --> (2)

Since these are 2 parallel lines with different y-intercepts, they will never meet
