Answer:
1×10^8
Step-by-step explanation:
First, multiply 1 million by 100 because 1 dollar is worth one hundred pennies. In total, it takes 100000000 pennies for 1 million dollars. Then, because there are 8 zeros, it would be 1 times 10 to the 8th power.
Answer:
y=-2 or y=3
Step-by-step explanation:
Y^2-y-6=0
y^2-3y+2y-6=0
y(y-3)+2(y-3)=0
(y+2)(y-3)=0
y=-2 or y=3

Answer:
12.1%
Step-by-step explanation:
First calculate the z-score:
z = (x − μ) / σ
z = (55000 − 48000) / 6000
z = 1.17
Look up in a z-score table.
P(z>1.17) = 1 − 0.8790
P(z>1.17) = 0.1210
There's a 12.1% probability that a randomly selected individual with a master's in statistics will have a starting salary of at least $55,000.
Answer:
There are 5 multiple choice questions
Step-by-step explanation:
Let
m ----> the number of multiple choice in a test
s ----> the number of short answer in a test
we know that
The test has 20 questions
so
----> equation A
A test is worth 50 points
so
----> equation B
Subtract equation A from equation B
Find the value of m
therefore
There are 5 multiple choice questions
