How to divide with decimals in the divisor.

Semmy [17]

Answer:

Step-by-step explanation:

Move the decimal point in the divisor and dividend. Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to ...

Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.

Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place. ...

Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather app

Sunny_sXe [5.5K]

Answer:

There is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5

Step-by-step explanation:

From the question we are told that

The population mean is less than 1.5

The sample size is n = 7

The sample data is 2, 0, 1, 5, 0, 2, and 3

Generally the sample mean is mathematically represented as

$\= x = \frac{ \sum x_i }{ n }$

=> $\= x = \frac{ 2 + 0 + 1 + 5 + 0 + 2 + 3 }{ 7 }$

=> $\= x = 1.857$

Generally the standard deviation is mathematically represented as

$\sigma = \sqrt{\frac{\sum (x_i - \= x)^2}{n} }$

=> $\sigma = \sqrt{\frac{ (2 - 1.857)^2 + (0 - 1.857)^2 +\cdots (3 - 1.857)^2}{7} }$

=> $\sigma = 1.773$

The null hypothesis is $H_o : \mu = 1.5$

The alternative hypothesis is $H_a : \mu < 1.5$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }$

=> $z = \frac{\= x - 1.857 }{ \frac{1.773 }{\sqrt{7} } }$

=> $z = 0.53$

Generally the p-value is mathematically represented as

$p-value = P(z < 0.53 )$

From the z-table

$P(z < 0.53 ) = 0.70194$

So

$p-value = 0.70194$

From the values obtained we see that $p-value > 0.05$

Here there is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5

Child admission is 5.50 and adult admission is 8.80, twice as many adult tickets as child tickets were sold, for a total of 669.

Vlad1618 [11]

Answer:

The answer to your question is: 29 tickets for children and 58 tickets for men.

Step-by-step explanation:

Child = c = $ 5.50

Adult = a = $8.80

Equation

a = 2c

5.5c + 8.8a = 669.9

5.5c + 8.8(2c) = 669.9

5.5c + 17.6c = 669.9

23.1c = 669.9

c = 669.9 / 23.1

c = 29

a = 2(29)

a = 58

A circular plate has a crack along the line AB, as shown below: A circular plate is shown. The center of the plate is labeled as

makkiz [27]

Well, since point A represents the center, and B represents a point on the outer line of the circle, segment AB would represent the radius, since the radius represents the length from the center to the outside of a circle

Hope this helps
