Answer:
B. 26,606.63
Step-by-step explanation:
The area of Gateway National Recreation Area is about twenty-six thousand, six hundred six and sixty-three hundredths. Which shows this number in standard form? A. 26,606.3 B. 26,606.63
C. 26,660.63 D. 26,666.3
Solution
Break down and writing in numerals of twenty-six thousand, six hundred six and sixty-three hundredths.
Twenty six thousand = 26,000
Six hundred six = 606
Sixty - three hundredth = 0.63
Adding
26,000 + 606 + 0.63
We have
26,606.63
The correct answer is B
Answer: Click (19.5) (19.401)
If you want to take 20% off $9, you must find 80% of $9. As 100% - 20% = 80%.
80% turns out to be 4/5, 8/10 or 0.8.
8/10 x 9
= 72/10
= 7.2

Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
Answer:
There is enough statistical evidence to support the claim that the survey is not accurate.
Step-by-step explanation:
We have to perform a test of hypothesis on the proportion.
The claim is that the proportion of families that own stock differs from 48.8%.
Then, the null and alternative hypothesis are:
The significance level is 0.05.
The sample. of size n=250, has a proportion of p=0.568.
The standard error of the proportion is
The z-statistic can now be calculated:
The P-value for this two-tailed test is then:
As the P-value is smaller than the significance level, the effect is significant. The null hypothesis is rejected.
There is enough evidence to support the claim that the survey is not accurate.
