Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 125 millimeters, and a standard deviation of 7
millimeters.
If a random sample of 44 steel bolts is selected, what is the probability that the sample mean would be greater than 127.1 millimeters? Round your
answer to four
decimal places
Answers
Answer:
P(X > 127.1) = 0.0233
Step-by-step explanation:
We are given;
Population mean; μ = 125 mm
Sample mean; x¯ = 127.1 mm
Sample size; n = 44
Standard deviation; σ = 7 mm
Formula for test statistic is;
z = (x¯ - μ)/(σ/√n)
z = (127.1 - 125)/(7/√44)
z = 2.1/1.0553
z = 1.99
From z-table attached;
P(X > 127.1) = P(z > 1.99) = 1 - 0.97670 = 0.0233

angles sum: 180(6-2) = 720
50 + 37 + 42 = 129
129 + 5x + 7x - 1 + 3x + 40 = 720
15x + 168 = 720
15x = 552
x = 36.8
check:
129 + 5(36.8) + (3(36.8) + 40) + (7(36.8) - 1) = 720
Correct answer??
180-50 = 130
180-37 = 143
180-42 = 138
Known internal angles:
130 + 143 + 138 = 411
15x + 39 + 411 = 720
15x = 270
x = 18

Find the equation for the line that passes through (4, - 8) that has slope - 2. Give your answer in
point-slope form. You do not need to simplify.
Answers
Answer:
y+8=-2(x-4)
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) where m is the slope, and (x1,y1) is a point.
We are given all of that information:
slope: -2
point: (4,-8)
substitute the numbers into the equation
y--8=-2(x-4)
we can make --8 to positive 8
so:
y+8=-2(x-4)
this is the equation in point-slope form

If 10 club members each collect the same number of canned goods, which inequality and graph represent the minimum number of canned goods, n, each club member must collect for the club to meet the goal? (HOW DID YOU GET YOUR ANSWER, PLEASE SHOW ME YOUR WORK!!)
A. 10n+30<500
B. 10n+30≥500
C. 30n+10≤500
D. 30n+10>500
Answers
Answer:
The correct answer is 10n ≥ 470.
Step-by-step explanation:
Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.
They already collected 30 canned goods, therefore we can subtract this quantity from out goal.
500 - 30 = 470
Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.
