what is 20% of 180
please i realy need to answer this

Answers

Answer 1

Answer:

20 percent * 180 =

(20:100)* 180 =

(20* 180):100 =

3600:100 = 36

Now we have: 20 percent of 180 = 36

Question: What is 20 percent of 180?

Percentage solution with steps:

Step 1: Our output value is 180.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$180=100\%$.

Step 4: Similarly, $x=20\%$.

Step 5: This results in a pair of simple equations:

$180=100\%(1)$.

$x=20\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{180}{x}=\frac{100\%}{20\%}$

Step 7: Again, the reciprocal of both sides gives

Step-by-step explanation:

Suppose Apple claims that the average wait time for a customer calling the Apple Care support line is 175 sec-onds. A random sample of 40 customers had an average wait time of 187 seconds. Assume the population standard deviation for wait time is 50 seconds. Using a 95% confidence interval, does this sample support Apple?

Answers

Answer:

yes

95% confidence intervals for the apple care support

(171.505 ,202.495)

Step-by-step explanation:

Step(i):-

Given Mean of the Population = 175 seconds

Random sample size 'n' =40

Mean of the sample = 187 seconds

Standard deviation of the Population = 50 seconds

Step(ii):-

95% confidence intervals for the mean is determined by

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

$(187 - 1.96\frac{50}{\sqrt{40} } , 187 + 1.96 \frac{50}{\sqrt{40} })$

(187 -15.495 , 187 +15.495)

(171.505 ,202.495)

Final answer:-

95% confidence intervals for the apple care support

Answers

The angle 7 is the alternative interior angle to angle 2.

Given that,In the diagram a || bWe need to find the alternate interior angle to <2 .Alternate interior angles are the angles that are formed when a transversal crosses two parallel lines.

They are the angles that are on opposite sides of the transversal and inside the two parallel lines.

Thus, in the given diagram, the angle that is opposite to angle <2 and is inside the two parallel lines a and b is the alternate interior angle to angle <2.

We can see that the alternate interior angle to angle <2 is <7. Therefore, the alternate interior angle to angle <2 is <7.

Answer:

the options are not numbered so I have added each of the correct answers under their corresponding question number. the answers in bold letters are right options from the question.

Step-by-step explanation:

a.)

the width of the interval decreases, since the standard error decreases. this is the answer to this question. this happens to a confidence interval as the sample size gets increased. that is if every other thing remains the same.

the answer to this question is that the interval gets wider since the t value required to Capture a larger proportion of the sampling distribution of the sample mean gets larger. so the last option is the answer to the question.

the margin of error shows the degree of random sampling error that is in the result of a survey. the correct answer to this question is this:

in a confidence interval for a population mean, the margin of error describes the difference between the sample mean and the population mean. Due to the random sampling method, different sample means will be different.

regarding this question, we use a z score because:

For large random samples the sampling distribution of the sample proportion is approximately normal.

Arithmetic is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots

Here, we have

Given: Tom has a water tank that holds 5 gallons of water. tell me this is water for my footing to fill six bottles they each hold 16 ounces and a picture that holds one over 2 gallons.

1 gallon = 128 ounces, 2 gallon = 256 ounces

6 bottles × 16 ounces = 96 ounces

2 gallon + 96 ounces = 256 + 96 ounces = 352 ounces

5 gallon = 5 × 128 = 640 ounces

= 640 - 352 = 288 ounces

Suppose the following information was collected, where x=diameter of tree trunk in inches, and y=tree height in feet
x 4 2 8 6 10 6
y 8 4 18 22 30 8
If the LSRL equation is y=-3.6 + 3.1x, what is your estimate of the average height of all trees having a trunk diameter of 7 inches?
A) 18.1
B) 19.1
C) 20.1
D) 21.2
E) 22.1

Answers

The estimate of the average height of all the trees having a trunk diameter of 7 inches is y = 18.1 feet. This is obtained by using the LSRL equation. Option A is the correct value.

What is the LSRL equation?

The LSRL equation is defined as the Least squares regression line. This is the line that minimizes the variance. So, it is the best line of fit for a set of data points.

The equation is in the form of Y = a + bX

Here a is the intercept and b is the slope.

Calculation:

It is given that,

X is given as the diameter of a tree trunk in inches

Y is given as the tree height in feet

The given data points are:

X: 4, 2, 8, 6, 10, 6

Y: 8, 4, 18, 22, 30, 8

For these data points, the least squares regression line is given by the equation Y = - 3.6 + 3.1X

So, the estimate of the average height of all trees having a trunk diameter of 7 inches is

Y = - 3.6 + 3.1X ⇒ Y = -3.6 + 3.1 × 7

⇒ Y = -3.6 + 21.7

∴ Y = 18.1 feet

If 15 percent of cars are blue and an observer's observation is 80 percent accurate, what is the probability that a car is, in fact, blue when the witness reports it as blue

Answers

The probability that a car is blue is the likelihood of the car being blue

The probability that a car is, in fact, blue when the witness reports it as blue is 12%

How to determine the probability?

The given parameters are:

P(Blue) = 15%

P(Accurate) = 80%

The probability that a car is blue, and the observation is accurate is calculated as:

P(Blue and Accurate) = P(Blue) * P(Accurate)

This gives

P(Blue and Accurate) = 15% * 80%

Evaluate the product

P(Blue and Accurate) = 12%

Hence, the probability that a car is, in fact, blue when the witness reports it as blue is 12%

One month Sam rented 3 movies and 5 video games for a total of $32. The next month, he rented 12 movies and 2 video games for a total of $29. Find the rental cost for a movie and a video game.

Answers

Using a system of equations, the rental cost for a movie and a video game is as follows:

Movie = $1.50Video game = $5.50.

What is a system of equations?

A system of equations is two or more equations solved concurrently or at the same time.

A system of equations is also described as simultaneous equations.

Movies Video Total

Games Cost

First month rental 3 5 $32

Second month rental 12 2 $29

Let the rental cost per movie = x

Let the rental cost per video game = y

Equations:

3x + 5y = 32 ... Equation 1

12x + 2y = 29 ... Equation 2

Multiply Equation 1 by 4:

12x + 20y = 128 ... Equation 3

Subtract Equation 2 from Equation 3:

12x + 20y = 128

12x + 2y = 29

18y = 99

y = 5.5

Substitute y = 5.5 in Equation 1 or 2:

12x + 2y = 29

12x + 2(5.5) = 29

12x + 11 = 29

12x = 18

x = 1.5

Thus, based on simultaneous equations, the rental cost for a movie is $1.50 while a video game's is $5.50.
