Alberto ran a race at a speed of 9 meters per second. Omar had a 6 meter head start and ran at a speed of 7 meters per second. B
zloy xaker [14]

Answer: Alberto run 27 meters.

Time taken By Alberto=3 seconds


Step-by-step explanation:

Let d be the distance Alberto ran to catch Omar.

Then, distance ran by Omar=x-6

Also, \text{Time}=\frac{\text{Distance}}{\text{Speed}}

Since, both started running at the same time.

Time taken By Alberto=\frac{x}{9}

Time taken By Omar=\frac{x-6}{7}

Now, at the point they meet time taken by both is equal.

\frac{x}{9}=\frac{x-6}{7}\\\Rightarrow\ 7x=9(x-6)\\\Rightarrow7x=9x-54\\\Rightarrow9x-7x=54\\\Rightarrow\ 2x=54\\\Rightarrow\ x=27

Hence, Alberto run 27 meters.

Time taken By Alberto=\frac{27}{9}=3 seconds

umka21 [38]
Total tax bill is $9,004.50

Given:
Sales price         = 103,500
State sales tax   =        3.9%
County sales tax =        2.9%
City sales tax      =        1.9%

State sales tax    = 103,500 x 3.9% = 4,036.50
County sales tax = 103,500 x 2.9% = 3,001.50
City sales tax      = 103,500 x 1.9%  =<u>1,966.50</u>

NNADVOKAT [17]

Complete question :

A newspaper article indicated that 43 percent of cars with black seats are white, 46 percent of cars with black seats are blue, 7 percent of cars with black seats are red, and 4 percent of cars with black seats are black. A test was conducted to investigate whether the color of cars with black seats was consistent with the newspaper article. A random sample of cars of these colors was selected, and the value of the chi-square test statistic was x = 8.2. Which of the following represents the p-value for the test?

A) P(x2 ≥ 8.2) = 0.08

B) P(x2 ≥ 8.2) = 0.04

C) P(x2 ≤ 8.2) = 0.96

D) P (x2 = 8.2) = 0.00

E) The p-value cannot be calculated because the sample size is not given.

Answer:

P(χ² ≥ 8.2) = 0.04

Step-by-step explanation:

We need to obtain the degree of freedom ;

Number of levels, k - 1

k = (white, blue, red, black) = 4

df = k - 1= 4 - 1 = 3

The test statistic, χ² = 8.2

The Pvalue is the probability of a Chisquare statistic with 3 degree of freedom is equal to or more extreme than the statistic value, 8.2

Using the Pvalue for calculator from Chisquare statistic, at 3 degree of freedom

Pvalue(8.2, 3) = 0.042

Hence,

P(χ² ≥ 8.2) = 0.04
