For each pound there are 16 ounces.
Write an equation to express the total number of ounces (Z) in (Y) pounds.
Answer:
Z = 16Y
For instance, let's say we want to know how many ounces there are in 2 pounds.
We'd enter in Z = 16(2). This would be simplified to Z = 32. Now, we know that there are 32 ounces in 2 pounds.
A ball if thrown straight up into the air. The table shows the data collected over t seconds, where h(t) is the height of the ball, in feet. Which statement is true?
Answer: The maximum height of the ball was 2.5 seconds after it was thrown.
Step-by-step explanation:
As shown in the table, the ball started coming down after the third second and yet the height at both the second and third seconds were the same. This means that the ball hit its highest extent between the second and third seconds.
Taking an average of these digits will give;
= (2 + 3) / 2
= 2.5 seconds
The ball therefore hit its highest level at 2.5 seconds and then started its descent.

For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? What is the probability that the number of days of vacation taken is more than 21 days? Discuss the solutions and an explanation. Respond to your peers’ posts and offer your feedback on this topic.
Answer:
The answer is below
Step-by-step explanation:
The number of vacation days taken by employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? More than 21 days?
Answer: Z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}\\ \\x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
Given that: μ = 14, σ = 3
a) For x < 10
[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{10-14}{3}=-1.33[/tex]
From the normal distribution table, P(x < 10) = P(z < -1.33) = 0.0918
b) For x > 21
[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{21-14}{3}=2.33[/tex]
From the normal distribution table, P(x > 21) = P(z > 2.33) = 1- P(z < 2.33) = 1 - 0.9901 = 0.0099
Messages arrive at a computer at an average rate of 25 messages per second. The number of messages that arrive in 1 second is known to be a Poisson random variable. a. Find the probability that no message arrive in 1 second. b. Find the probability that more than 5 messages arrive in a 10-second period.
Answer:
a)[tex]1.3887943865 \times 10^{-11}[/tex]
b)P(X>5)=1
Step-by-step explanation:
[tex]P(X=x)=\frac{e^{-\lambda} \lambda^k}{k!}[/tex]
We are given that Messages arrive at a computer at an average rate of 25 messages per second.
[tex]\lambda = 25[/tex]
a) Find the probability that no message arrive in 1 second.
[tex]P(X=0)=\frac{e^{-25} (25)^0}{0!}\\P(X=0)=\frac{e^{-25} (25)^0}{0!}\\P(X=0)=1.3887943865 \times 10^{-11}[/tex]
b) Find the probability that more than 5 messages arrive in a 10-second period.
[tex]P(X>5)=1-P(X \leq 5)[/tex]
[tex]P(X>5)=1-\sum_{0}^{10} (P(X=0)+P(X=1)+........+P(X=5))[/tex]
P(X>5)=1

Answer:
um what is the question
Step-by-step explanation:
y=2/3x-4 i need help i do not get this does anybody know slopes
Step-by-step explanation:
slope in this case is 2/3
this equation is in slope intercept form
y=mx+b
m is slope
and b is y-intercept
so
m =2/3
b=-4
Answer: The slope is 2/3 (0.666...)
Step-by-step explanation: The slope is the coefficient of X in slope-intercept form. y=2/3x-4 is in slope-intercept form (y=mx+b) m = slope, b = y-intercept (the Y value when the X is equal to 0)
On a graph, it looks like this:
A study of 1000 randomly selected flights of a major airline showed that 798 of the flights arrived on time. What is the probability of a flight arriving on time? 399/500 500/399 101/500 500/101
Answer:
399/500
Step-by-step explanation:
the reason for this is because the area of the devision "1000 randomly selected flights of a major airline showed that 798 of the flights arrived on time" means that this is divided into places to make a full example
The probability of event of a flight arriving on time will be -
P(A) = 399/500.
What is Probability?
Probability is the extent to which an event is likely to occur and is measured by the ratio of the favorable cases to the total number of cases possible.
Given is a study of 1000 randomly selected flights of a major airline which showed that 798 of the flights arrived on time.
Let event A represents the arrival of flight on time.
Total number of favorable cases = 798
Total number of possible cases = 1000
Then the probability of event A will be -
P(A) = 798/1000 = 399/500
Therefore, the probability of event of a flight arriving on time will be -
P(A) = 399/500

Given that (x−1)^2 is a factor of ax^3+bx^2+1 , find a and b .
Key in the answer in the form a, b
Answer:
[tex]a=1[/tex]
[tex]b=-1[/tex]
Step-by-step explanation:
Once [tex](x-1)^2[/tex] is a factor and [tex](x-1)^2 = (x-1)(x-1)[/tex], we have that two roots of the cubic equation are equal to 1. So,
[tex]ax^3+bx^2+1 = (x-1)(x-1)(x-d)=0[/tex]
As [tex]d[/tex] the unknown root.
Expanding
[tex]ax^3+bx^2+1 = (x-1)(x-1)(x-d)=0[/tex]
[tex]ax^3+bx^2+1 = (x^2-2x+1)(x-d)=0[/tex]
[tex]ax^3+bx^2+1 = x^3-2x^2+x-dx^2+2dx-d=0[/tex]
Now, comparing the two expressions, we have
[tex]ax^3+bx^2+1 = x^3+(-2-d)x^2+(1+2d)x-d=0[/tex]
Therefore, know we know
[tex]a=1[/tex]
[tex]b=-2-d[/tex]
[tex]d=-1[/tex]
So,
[tex]b=-2-(-1)=-2+1=-1[/tex]

f of p is equal to 0 point 8 5 p plus open paren p plus 10 close paren
r(d(p))=0.85p+10
r times open paren d times p close paren is equal to 0 point 8 5 p plus 10
f(p)=0.85p⋅(p+10)
f of p is equal to 0 point 8 5 p times open paren p plus 10 close paren
d(r(p))=0.85p+8.50
d times open paren r times p close paren is equal to 0 point 8 5 p plus 8 point 5 0
Answer:
Step-by-step explanation:
0.85 + 10
The function that Annie can use to calculate both price changes is f(p) = 1.85p+10. Therefore, option A is the correct answer.
Given that, a discount function on each price, d(p)=0.85p and then increase the resulting price is r(p)=p+10.
What is discount?A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.
Now, the function that Annie can use to calculate both price changes
f(p) = d(p)+r(p)
⇒ f(p) = 0.85p+(p+10)
⇒ f(p) = 1.85p+10
The function that Annie can use to calculate both price changes is f(p) = 1.85p+10. Therefore, option A is the correct answer.

8(4K-4)=-5k+42 find k
Answer:
K = 2
Step-by-step explanation:
Simplifying
8(4k + -4) = -5k + 42
Reorder the terms:
8(-4 + 4k) = -5k + 42
(-4 * 8 + 4k * 8) = -5k + 42
(-32 + 32k) = -5k + 42
Reorder the terms:
-32 + 32k = 42 + -5k
Solving
-32 + 32k = 42 + -5k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '5k' to each side of the equation.
-32 + 32k + 5k = 42 + -5k + 5k
Combine like terms: 32k + 5k = 37k
-32 + 37k = 42 + -5k + 5k
Combine like terms: -5k + 5k = 0
-32 + 37k = 42 + 0
-32 + 37k = 42
Add '32' to each side of the equation.
-32 + 32 + 37k = 42 + 32
Combine like terms: -32 + 32 = 0
0 + 37k = 42 + 32
37k = 42 + 32
Combine like terms: 42 + 32 = 74
37k = 74
Divide each side by '37'.
k = 2
Simplifying
k = 2
