In 2014, new cars had an average fuel efficiency of 27.9 miles per gallon with a standard deviation of 6.8 miles per gallon. a sample of 30 new cars is taken. [6 points] a) what is the probability the sample has a mean gas mileage between 27 and 29 miles per gallon?
The probability of the sample having a mean gas mileage between 27 and 29 miles per gallon will be 0.0116.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
In 2014, new cars had an average fuel efficiency of 27.9 miles per gallon with a standard deviation of 6.8 miles per gallon. a sample of 30 new cars is taken.
Then the probability the sample has a mean gas mileage between 27 and 29 miles per gallon will be
The value of the z-score at x = 27, we have
[tex]z = \dfrac{27 - 27.9}{6.8}\\\\z = -0.13[/tex]
The value of the z-score at x = 29, we have
[tex]z = \dfrac{29 - 27.9}{6.8}\\\\z = 0.16[/tex]
Then the probability will be
[tex]\begin{aligned} P(-0.13 < z < 0.16 ) &= P (z < 0.16) - P(z > -0.13) \\\\&= P (z < 0.16) - [ 1 - P(z < -0.13) ]\\\\&= 0.56425 - (1 -0.44735)\\\\&= 0.0116 \end[/tex]

Instructions: find the marked angle in the triangle diagrams and explain how you figured it out.
(Image below) Also giving brainlyest to the person with a good explanation
Answer: 84 degrees
Step-by-step explanation:
this triangle is an isosceles triangle meaning two sides are of equal length ( the two sides in this case being the ones marked with the two lines // and // ) and that also means the triangle will have two equal angles (48 and 48) how do we know that? The triangle looks like this essentially: (see image below) where angle a = to angle b
a triangles angles added up always =180 degrees
Since we proved angle a is equal to angle b, we should be able to also subtract them from 180 to find angle c. 48+48=96
and simply subtract 96 from 180 to get 84 degrees.
therefore the angle is 84 degrees

The area of a gym is 3,403 m squared. If the width of the gym is 41 m, what is the length of the gym?
Type your numerical answer below (without units). If necessary, round to the nearest whole number.
Answer:
83 m
Step-by-step explanation:
The missing dimension can be found by using the area formula. Fill in the given values, and solve for the remaining unknown value.
__
A = LW . . . . . area of a rectangle of length L and width W
3403 m² = L(41 m) . . . . with given values filled in
L = (3403 m²)/(41 m) = 83 m . . . . . . divide by the coefficient of L
The length of the gym is 83 meters.

Work out the circumference of this circle.
Take to be 3.142 and write down all the digits given by your calculator,
13 cm
diameter= 13 cm
to find:the circumference of the given circle.
solution:[tex]c = \pi \: d[/tex]
[tex]c = 3.142 \times \: d[/tex]
[tex]c = 3.142 \times 13[/tex]
[tex]c = 40.846 \: cm[/tex]
hence, the circumference of the given circle is 40.846 cm
First, we'll have to change the diameter to radius by dividing the diameter by 2.
[tex]\large\boxed{Formula: r= \frac{d}{2}}[/tex]
So we'll have to divide 13 by 2.
Substitute the values according to the formula.
[tex]r= \frac{13}{2}[/tex]
[tex]\bold{6.5 \: cm}[/tex]
Now, we can find the circumference.
[tex]\large\boxed{C= 2\pi{r}}[/tex]
Substitute the values according to the formula.
[tex]C= 2\times\pi\times6.5[/tex]
Calculate value:
[tex]\large\boxed{C= 40.8407045 \: cm}[/tex]
Therefore, the circumference of the given circle is 40.8407045 centimeters.

convert 0.29 to a percentage
Answer:
0.29 as a percentage is the same as 29%
Step-by-step explanation:
it’s going to be 29% because you just pretend that there isn’t a 0. In front of the 29 and you have 29%.
The decimal number 0.29 is equivalent to 29% when expressed as a percentage.
Given decimal is 0.29.
To convert a decimal number to a percentage, multiply it by 100 and add the percentage symbol (%).
In this case, to convert 0.29 to a percentage
= 0.29 x 100
= 29
Therefore, 0.29 is equivalent to 29% as a percentage.

The perimeter of an isosceles triangle is 4 times the length of the shortest side. The longer sides are 4.5 ft longer than the shortest side. What is the length of each side of the triangle?
Answer:
Shorter side = 9 feetLonger sides = 13.5 feetStep-by-step explanation:
Let :
Shorter side = xLonger sides = x + 4.5Perimeter = 4xSolving
2(x + 4.5) + x = 4x2x + 9 + x = 4xx = 9 feetSolution
Shorter side = 9 feetLonger sides = 13.5 feetAnswer:
short side: 9 ftlonger sides: 13.5 ftStep-by-step explanation:
The given information lets us write two equations relating the side lengths.
__
setupLet L and S represent the lengths of the longer and shorter sides. We are told ...
S + L + L = 4S . . . . . the perimeter is 4 times the short side length
L = 4.5 +S
__
solutionUsing the second equation to substitute for L in the first equation, we have ...
S +2(4.5 +S) = 4S
9 = S . . . . . . . . . . . . . simplify, subtract 3S
L = 4.5 +S = 13.5
The shortest side is 9 ft; the longer sides are 13.5 ft.
__
Additional comment
The perimeter is 36 ft.

Step-by-step explanation:
3x - y = 17
-x + y = -7
here we can find the sum of the two equations
2x = 10
x = 5
now we can just plug in the value of x to find y
-(5) + y = -7

Rowan bought a bag of jelly beans that
contained 54 ounces of jelly beans. She
divided the jelly beans into bags that
contained 6.75 ounces each. Write a division
equation that could be used to find the
number of bags she made.
Answer:
[tex]\sf y=\dfrac{54}{6.75}[/tex] or [tex]\sf y=54 \div 6.75[/tex]
(where y is the number of bags made)
Step-by-step explanation:
If Rowan bought a 54 oz bag of jelly beans and divided them into bags that each contained 6.75 oz, to find how many bags were made, divide the total weight of jelly beans by the weight of each bag.
⇒ Number of bags = Total weight ÷ bag weight
= 54 ÷ 6.75
= 8
Therefore, Rowen made 8 bags.
Total weight of jelly beans initially
54ozEach bag contains
6.75ozSo the equation should be
Bags=54/6.75Or
B=54/6.75If we solve we get total bags as 8

whats the median 19 19 20 21 2324 25 26 27 29 33
Answer:
The median is also known as the middle of the data set when it has already been sorted. So the first thing that we need to do is make sure that our data set is fully sorted.
[tex]19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33[/tex]
Now that we have our data set sorted, we can located the middle. Since this data set has 11 numbers that means number 6 is going to be our median. Counting from the left we get that our median is 24.
Hope this helps! Let me know if you have any questions
Answer: The answer is 24.
Step-by-step explanation: To find the median, you put all your data in order from least to greatest, which would look like:
19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33
Then, cross out the numbers from front to back until you find your middle number.
19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33

A population of snails is tripling every week if the population started with 15 snails how many snails will there be after 14 weeks?
Answer:
There is 57 snails after 14 weeks
Step-by-step explanation:
Creating an equation:tripling every week means 3x
NOTE: x is defined as the number of weeks
started with 15 snails means at day 0 (x = 0 also known as y intercept)
y = mx + b m is the slope, b is the y intercept
our equation: y = 3x + 15
after 14 weeks (x = 14):y = 3(14) + 15
y = 42 + 15
y = 57
