Looking into the sky one night, Tori wondered how far into outer space she would get if she drove a car for 3.21 × 103 hours at a rate of 70mph. She calculated and determined that a car travelling at 70 mph covers approximately 1.13 × 105 meters per hour. Tori wrote this expression to determine the distance she would travel into outer space. (3.21 × 103)(1.13 × 105) Estimate the distance travelled. Almost-equals30 × 1015 meters Almost-equals3 × 108 meters Almost-equals30 × 108 meters Almost-equals3 × 1015 meters

find the value of x. write your answer in simplest radical form

Answers

Answer:

[tex]x = 4 \sqrt{2} [/tex]

Step-by-step explanation:

To find the value of x we can use either sine or cosine

Using cosine we have

[tex] \cos(\theta) = \frac{adjacent}{hypotenuse} [/tex]

From the question

x is the hypotenuse

4 is the adjacent

We have

[tex] \cos45= \frac{4}{x} \\ x \cos45 = 4 \\ x = \frac{4}{ \cos(45) } [/tex]

We have the final answer as

[tex]x = 4 \sqrt{2} [/tex]

Hope this helps you

Step-by-step explanation:

Sinø=opp/hyp

Sin45=4/x. (× b.s by x)

xSin45=4. (÷ b.s by Sin 45)

x=4/Sin45

Which number is a counterexample to the following statement? All numbers that are divisible by 2 are divisible by 4.

A. 0
B. 12
C. 28
D. 42

Answers

Using divisibility concepts, a counterexample to the statement is given by option the number 42, option D.

-------------

If the remainder of the division of A by B is 0, it is said that A is divisible by B.

-------------

In option A, 0 is divisible by both 2(0/2 = 0) and 4(0/4 = 0), so it is not a counterexample.In option B, 12 is divisible by both 2(12/2 = 6) and 4(12/4 = 3), so it is not a counterexample.In option C, 28 is divisible both by 2(28/2 = 14) and 4(14/2 = 7), so it is not a counterexample.In option D, 42 divided by 4 is 10 with a remainder of 2, thus 42 is not divisible by 4, being a counterexample to the statement.

D. The value is a statistic because it is a numerical measurement describing some characteristic of a sample.

Answers

Answer:

D. The value is a statistic because it is a numerical measurement describing some characteristic of a sample.

Step-by-step explanation:

A survey found that 75% of all respondents were optimistic. We consider 75% of all respondents is a sample from over all population, so it's a statistic.  Value of statistics are e.g sample mean, sample proportion etc .

It is important to understand that the numerical measurement describing some characteristic of a population is called as parameter.  e.g. population mean , population proportion etc. Hence, it is not correct.

Jean masear is a saw operator in a lumber mill. He works 40 hours a week and earns $630 per week. What is his hourly pay rate

Answers

360/40=15.75 You have to divide 360 in 40

Answer:

[tex]\boxed {\tt \$15.75 \ per \ hour}[/tex]

Step-by-step explanation:

We want to find Jean's hourly pay rate. In other words, his pay per hour.

We can find the pay rate by dividing the money he is paid by the number of hours worked.

[tex]pay \ rate =\frac{money \ paid }{hours}[/tex]

He is paid $630 for 40 hours.

[tex]money \ paid= $630 \\hours= 40\ hours[/tex]

[tex]pay \ rate = \frac{\$630}{40\ hours}[/tex]

Divide.

[tex]pay\ rate = \$15.75 / hour[/tex]

His hourly pay rate is $15.75 per hour.

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the first city was
7.5%, and the tax in the second city was 7%. The total hotel tax paid for the two cities was $547.50. How much was the hotel charge in each city before tax?

Answers

Answer:

let the hotel charge before tax for second hotel be x

then the hotel charge before tax for first hotel = x+1500

tax of first hotel = 7.5% * (x+1500) = (7.5x+11250)/100

tax from second hotel= 7% of x = 7x/100

total tax = 547.50

7x/100 + (7.5x+11250)/100 =547.50

14.5x = 54750-11250

14.5x= 43500

x= 3000

hotel charge in first city = 4500

in second city =3000

Step-by-step explanation:

For the first dataset ...

  d1 = {20, 22, 24, 28, 29, 29, 30}

The deviations from the mean of 26 are ...

  d1 -mean(d1) = {-6, -4, -2, 2, 3, 3, 4}

so the total of the absolute values of these is 24. Since there are 7 numbers, the mean of the absolute deviations is ...

  mad = 24/7

__

For the second dataset ...

  d2 = {12, 15, 21, 30, 33, 35, 36}

The deviations from the mean of 26 are ...

  d2 -mean(d2) = {-14, -11, -5, 4, 7, 9, 10}

so the total of the absolute values of these is 60. Again, there are 7 numbers, so the mean of the absolute deviations is ...
