On a test that has a normal distribution, a score of 32 falls three standard
deviations below the mean, and a score of 82 falls two standard deviations
above the mean. Determine the mean of this test.
Answers
Answer:
Mean = 62
Step-by-step explanation:
X = mean ± sd
82 = mean + 2(s.d) - - (1)
32 = mean - 3sd ___(2)
82 = mean + 2sd
82 - 32= 2sd + 3sd
50 = 5sd
sd = 50/5
sd = 10
From (2):
32 = mean - 3sd
32 = mean - 3(10)
32 = mean - 30
32 + 30 = mean
62 = mean
Jerry ordered 4 items online. He is charged $2.91 per pound for shipping. The items weighed 4.3 pounds, 2 pounds, 3.8 pounds, and 5.9 pounds. How much will he be charged for shipping? (Round to the nearest cent).
Answers
Answer:
46.56 pounds
Step-by-step explanation:
Given data
4.3 pounds
2 pounds
3.8 pounds, and
5.9 pounds
Let us find the total weight of all the items
=4.3+2+3.8+5.9
=16 pounds
We are told that he is charged $2.91 per pound for shipping
Hence the cost of shipping 16 pounds is
=2.91*16
=46.56 pounds

Solve the inequality.
- 5x > 25
Answers
Answer and Step-by-step explanation:
Divide -5 from both sides of the inequality.
x < -5 is the answer.
Here's Why:
If you were to add 5x to both sides, it results in this:
0 > 25 + 5x
Now, we subtract 25 from both sides.
-25 > 5x
When we divide 5 from both sides, we see that it results in -5 > x, which is the same as x < -5.
#teamtrees #PAW (Plant And Water)
Answer: x < -5
1. Divided both sides by -5.
X < -25/5
2. Simplify 25/5 to 5.
X < -5

what is the slope and y intercept of -5x+3y=-9
Answers
Answer:
slope = 5/3
y-intercept = (0,-3)
Step-by-step explanation:
Make the equation in slope-intercept form:
-5x+3y=-9
add 5x on both sides
3y=5x-9
divide by 3 on both sides
y=5/3x-3
slope = 5/3
y-intercept = (0,-3)

Oatmeal is packaged in a right circular cylindrical container that has a radius of 7 centimeters and a height of 16 centimeters.
What is the surface area of this container in terms of pi?
a. 176
b. 254
c. 322
d. 440
Answers
Answer:
c. 322
Step-by-step explanation:
Surface area of cylinder = 2πr² + 2πrh.
SA in terms of π = π(2r² + 2rh) →
π(2(7)² + 2(7)(16)) →
π(2(49) + 2(112)) → π(98 + 224) → π(322)

 what would be the equation of a line that passes through (3,-4) with slope 2/3
Answers
Answer:
y = 2/3x - 6
Step-by-step explanation:
Use the slope intercept equation, y = mx + b
Plug in the slope and given point, then solve for b
y = mx + b
-4 = 2/3(3) + b
-4 = 2 + b
-6 = b
Plug in the slope and b into the equation
y = 2/3x - 6
So, the equation of the line is y = 2/3x - 6

Two sides of a right triangle have lengths of 46 centimeters and 23 centimeters. The third side is not the hypotenuse. How long is the third side? Round your answer to the nearest centimeter.
Answers
Answer:
about 40 cm.
Step-by-step explanation:
I know the length of the third side is 40cm because I used the Pythagorean theorem.
a^2+b^2=c^2 The "a" and "b" values are the lengths of the legs of the triangle, while "c" is the length of the hypotenuse. We know the third side of this triangle is not the hypotenuse.
* The longest side of a right triangle is the hypotenuse, so we know the length of the hypotenuse is 46cm.
Therefore, we plug our values into the Pythagorean theorem.
23^2+b^2=46^2
529+b^2=2116
Next, we subtract 529 on both sides.
b^2=1587
Next, find the square root of 1587, so we can find the true value of b.
b=39.8371685741
Rounded to the nearest centimeter is 40.
In conclusion, the length of the third side is 40cm.
