Answer:

The answer is B. m∠ POS + m∠ POR = 180

step-by-step explanation:

Because if you already know that m∠POQ equals 90 because it is a right angle

Then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45

now you have the measurement for the two acute angles 45

which makes m∠POS = 45 and m∠QOR =45

NOW YOU HAVE TO ADD 90 AND 45 AND 45 ALL TOGETHER THEN YOU WILL HAVE 180

You are interested in purchasing a new car. One of the many points you wish to consider is the resale value of the car after 5 y

gulaghasi [49]

Answer:

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

(11,688.68 , 12,511.32)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 17

mean of the sample x⁻ = 12,100

Standard deviation of the sample (S) = 800

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

Step(ii):-

Degrees of freedom ν =n-1 = 17-1 =16

$t_{(16 , 0.05)} = 2.1199$

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

$(12,100 - 2.1199\frac{800}{\sqrt{17} } , 12,100 + 2.1199 \frac{800}{\sqrt{17} } )$

(12,100 - 411.32 , 12,100 + 411.32)

(11,688.68 , 12,511.32)

The area of a triangle is 10 square meters. The height is one meter longer than the base. What are the lengths of the base and h

Kamila [148]

Answer:

b=4, h=5

Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5

A company conducted a survey to see whether its new toothpaste was morepopular with children or adults. Of the children surveyed

Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

$Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%$

Let us calculate the percentage of adult that used toothpaste

$Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%$

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C

Fred purchased a jacket for $20 and 5 T-shirts. Each T-shirt cost the same amount. The total cost was $85. How much did each T-s

snow_tiger [21]

Answer:

Each t-shirt cost 13 dollars.

Step-by-step explanation:

Since the jacket was 20 bucks, we can set that aside:

85-20=65

Now that we've set that aside, there are five t-shirts. If they all cost the same, that means we can divide!

65/5=13

How to check?

Use inverse operations: 13*5=65

Re-add the 20 bucks from the jacket, and the bill is complete again! Use inverse operations: 13*5=65

Each shirt costs $13.
