Step-by-step explanation:
The B of years it took to the given principal to amount $910 is 3.4 years.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].
Given that, principal =$750, rate of interest =1.9% and amount=$910.
Let the number of years be x and compounded quarterly.
Here, 910=750(1+ 1.9/100)³ˣ
910/750 =(1+0.019)³ˣ
1.213=(1.019)³ˣ
Take the logarithm of both sides of the equation to remove the variable from the exponent.
Exact Form:
x=ln(1.213)/3ln(1.019)
Decimal Form: 3.419
≈ 3.4 years
Therefore, the number of years it took to principal to reach $910 is 3.4 years.

Graph the line with the equation y - 1/4x +5.
Answer:
Y-intercept=5 Slope=-1/4
Step-by-step explanation:
Plot a point on (0,5)
From that point, you can either go down 1 point and right 4 points, or you can go up 1 point and go left 4 points.
Whichever one you choose, plot a point after each 2 movements
if this is too confusing, another point would be (4, 4) then make a line through both points.

How many grams of a radioactive kind of neodymium will be left after 33 days if the half-life is 11 days and you start with
160 grams?
Answer:
20 grams will be left.
Step-by-step explanation:
Half-life is 11 days
This means that in each 11 days, you lose 50% of the amount.
33 days
33/11 = 3 half-lifes.
You start with 160 grams
After 11 days: 160/2 = 80 grams
After 22 days: 80/2 = 40 grams
After 33 days: 40/2 = 20 grams.
20 grams will be left.

a. How much warmer is 82 than 40?
b. How much warmer is 82 than -40?
a. What is the difference in height between 30 m up a cliff and 87 m up a cliff? What is the distance between these positions?
b. What is the difference in height between an albatross flying at 100 m above the surface of the ocean and a shark swimming 30 m below the surface? What is the distance between them if the shark is right below the albatross?
Answer:
a. 42
b. 122
a. 57
b. 130
Step-by-step explanation:
For problem A:
because both of these values have positive numbers, just use normal subtraction
82 - 40 = 42 degrees warmer
For problem B:
because we are subtracting a negative number from a positive number, we add both of these numbers because 82 - -40 can also be equal to 82 + 40
82 - -40 = 122
For problem A:
the sentences 30m up a cliff and 87m up a cliff are describing positive values.
87 - 30 = 57
For problem B:
Now in this problem, the sentence 100m above the surface is describing a positive value, but the sentence 30m below the surface describes a negative value
how do I know this?
if the sentences above the surface and below the surface are describing positive and negative values, then there has to be a neutral value ( which is 0)
0 meters = the surface, because they are using both positive and negative values, meaning that the surface is the neutral value
by using a number line, you can draw it out like this
below the surface-------------------------the surface----------------------------above the surface
-30--------------------------------------------0--------------------------------------------100
therefore, 100 - - 30 = 100 + 30 = 130
A carpenter cuts a board 3 3/8 feet off the end of a board that is 6 1/2 feet long. How long is the remaining piece of board?
Answer:
[tex]6 \times \frac{1}{2} - 3 \times \frac{3}{8} = 1 \times \frac{7}{8} [/tex]
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
The remaining piece of the board when [tex]3\frac{3}{8}[/tex] feet is cut off from the end of the board of [tex]6\frac{1}{2}[/tex] feet is
[tex]3\frac{1}{8}[/tex] feet
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example:
1/2, 1/3 is a fraction.
1/2 of 4 is 2.
1/4 of 20 is 5.
We have,
Length of the board = [tex]6\frac{1}{2}[/tex] feet.
The length cut off from the board = [tex]3\frac{3}{8}[/tex] feet.
The remaining length of the board:
= [tex]6\frac{1}{2}[/tex] - [tex]3\frac{3}{8}[/tex]
= 13/2 - 27/8
Find the Lcm of 2 and 8.
The Lcm of 2 and 8 is 8.
= (13x4 - 27) / 8
= (52 - 27) / 8
= 25/8
Write it in a mixed fraction.
= [tex]3\frac{1}{8}[/tex] feet
Thus,
The remaining piece of the board when [tex]3\frac{3}{8}[/tex] feet is cut off from the end of the board of [tex]6\frac{1}{2}[/tex] feet is [tex]3\frac{1}{8}[/tex] feet.

Hello. I have no idea how to solve this question below about Probability. I would appreciate if you show how to solve it step-by-step. Thank you so much.
Alonzo, Bob, and Casper work bussing tables at a restaurant. Alonzo has a 70% chance, Bob has a 10% chance, and Casper has a 20% chance of bussing tables in the middle area of the restaurant. If Alonzo is bussing tables, he has a 6% chance of breaking a dish. If Bob is bussing tables, he has a 2% chance of breaking a dish. Finally, if Casper is bussing tables, he has a 3% chance of breaking a dish. If there is a broken dish in the middle of the restaurant, what is the probability it was broken by Casper?
The probability the dish was broken by Casper if he bussed tables is;
P(Casper bussing tables and breaking dish) = 0.6%
We are given the three probabilities each for Alonzo, Bob and Casper for bussing tables and also in case any dish should break.
P(Alonzo bussing tables) = 70% = 0.7
P(Bob bussing tables) = 10% = 0.1
P(Casper bussing tables) = 20% = 0.2
P(Alonzo breaking a dish) = 6% = 0.06
P(Bob breaking a dish) = 2% = 0.02
P(Casper breaking a dish) = 3% = 0.03
This is all about independent events as the probability of breaking the dishes does not increase or decrease with the bussing of the tables.
Thus; P(A and B) = P(A) + P(B)
Thus, if a dish is broken, the probability that it was broken by Casper is;
P(Casper bussing tables and breaking dish) = P(Casper bussing tables) × P(Casper breaking a dish)
P(Casper bussing tables and breaking dish) = 0.2 × 0.03
P(Casper bussing tables and breaking dish) = 0.006 or 0.6%

Step-by-step explanation:
According to a recent poll, 25% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. According to recent studies, cholesterol levels in healthy adults from the area average about 260 mg/dL, with a standard deviation of about 35 mg/dL, and are roughly Normally distributed. Assume that the standard deviation of the recent studies is accurate enough to be used as the population standard deviation. If the cholesterol levels of a sample of 49 healthy adults from the region is taken answer parts (a) through (d). A) What is the probability that the mean cholesterol level of the sample will be no more than 210? B) What is the probability that the mean cholesterol level of the sample will be between 205 and 215? C) What is the probability that the mean cholesterol level of the sample will be less than 200?D) What is the probability that the mean cholesterol level of the sample will be greater than 222?
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\for\ a \ sample(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\where\ x=raw\ score,\mu=mean, \sigma=standard deviation[/tex]
Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL
a) For x < 210:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{210-260}{35/\sqrt{49} } =-10[/tex]
From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001
b) For x > 205:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{205-260}{35/\sqrt{49} } =-11[/tex]
For x < 215:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{215-260}{35/\sqrt{49} } =-9[/tex]
P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009
c) For x < 200:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{200-260}{35/\sqrt{49} } =-12[/tex]
From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001
d) For x > 222:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{222-260}{35/\sqrt{49} } =-7.6[/tex]
From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999
