Jake's test scores are 86, 70, 72, 100, 96, and 80. What must Jake earn of his last test to earn a mean grade of exactly 85%?
Answers
Answer:
91
Step-by-step explanation:
Mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be his test score of his last test , then
[tex]\frac{86+70+72+100+96+80+x}{7}[/tex] = 85 ( multiply both sides by 7 )
504 + x = 595 ( subtract 504 from both sides )
x = 91

A sphere just fits inside a cube with edges 20 in. Long. What is the volume of the sphere? What is the volume of the cube? What is the volume of the space between the cube and sphere?
Answers
Answer:
Step-by-step explanation:
Volume of a cube = (side)³
= (20)³
= 8000 cubic in.
Volume of the sphere which just fits in = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here, r = Radius of the sphere
Since, sphere just fits in, radius of the sphere = half of the dimension of the cube
r = [tex]\frac{20}{2}[/tex]
r = 10 in
Therefore, volume of the sphere = [tex]\frac{4}{3}\pi (10)^3[/tex]
= 4188.79 cubic inch
Volume of the space between the cube and sphere = 8000 - 4188.79
= 3811.21 cubic inch

Step-by-step explanation:
You need to translate all the points to the right 3 and up 6
Therefore, you are going to use this formula:
(x,y) ⇾ (x + 3, y + 6)
This is the same format as the previous problem, if you have noticed.
Using this, plug in each coordinate, starting with P (5, -1)
(5, -1) ⇾ ( 5 + 3, -1 + 6)
(5, -1) ⇾ ( 8, 5 )
P[tex]^{1}[/tex] = (8, 5)
Now point Q, (0, 8)
(0, 8) ⇾ (0 + 3, 8 + 6)
(0, 8) ⇾ ( 3, 14 )
Q[tex]^{1}[/tex] = (3, 14)
And last but not least, the point R, (7, 5)
(7, 5) ⇾ (7 + 3, 5 + 6)
(7, 5) ⇾ ( 10, 11 )
R[tex]^{1}[/tex] = (10, 11)
Therefore, P[tex]^{1}[/tex] = (8, 5), Q[tex]^{1}[/tex] = (3, 14), R[tex]^{1}[/tex] = (10, 11) is your answer. This is the 4th option or D.

Step-by-step explanation:
Given equation:
[tex]e^{4x-5}-7=11243[/tex]
Add 7 to both sides:
[tex]\implies e^{4x-5}-7+7=11243+7[/tex]
[tex]\implies e^{4x-5}=11250[/tex]
Take natural logs of both sides:

Mean = 8
The mean is the average number in a sequence. To find the mean we can simply use the following equation
(Sum of all numbers) ÷ (Amount of numbers)
The sum of the given numbers is 160
The amount of numbers is 20
So the mean = 160 ÷ 20 or 8.

Answer:
x = 24°
Step-by-step explanation:
here's your solution
=> measure of angle 1 = (6x)°
=> measure of angle 2 = (x + 12)°
=> we know that The sum of angles on a straight line is equal to 180°
=> so, (6x)° + (x + 12°) = 180°
=> 7x + 12° = 180°
=> 7x = 180° - 12°
=> 7x = 168°
=> x = 168°/7
=> x = 24°
=> angle 1 = 24°×6 = 144°
=> angle 2 = 24° + 12 = 36°
hope it helps 【◆◆】
Answer:
∠ 1 = 144°, ∠ 2 = 36°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and sum to 180° , that is
6x + x + 12 = 180
7x + 12 = 180 ( subtract 12 from both sides )
7x = 168 ( divide both sides by 7 )
x = 24
Then
∠ 1 = 6x = 6(24) = 144°
∠ 2 = x + 12 = 24 + 6 = 36°

Suppose that Clayton Kershaw of the Los Angeles Dodgers throws his fastball with a mean velocity of 94 miles per hour (mph) and a standard deviation of 2 mph and that the distribution of his fastball speeds can be modeled by a Normal distribution What percent of Kershaw’s fastballs will travel at least 100 mph?
Answers
Answer:
Step-by-step explanation:
ah, probability, so the std. deviation is 2 MPH, so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 std. deviations or 6 MPH to hit 100
99.7% of throws fall into that area of with in 3 std. deviations so that means
0.3% fall outside also , 1/2 of those will 3 std. deviations slow while the other half is fast
so
0.15% will be 100 or faster.... not many
0.15% is the percent of Kershaw’s fastballs will travel at least 100 mph.
What is Normal Distribution?A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
The standard deviation is 2 MPH, so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 standard deviations or 6 MPH to hit 100
99.7% of throws fall into that area of with in 3 standard deviations so that means
0.3% fall outside also , 1/2 of those will 3 standard deviations slow while the other half is fast
so 0.15% will be 100 or faster
Hence 0.15 percent of Kershaw’s fastballs will travel at least 100 mph.
