Answer:
f(5) = 32
g(5) = 40
Step-by-step explanation:
For f(x) we can realize that each term for the value of x is twice the value before it. This means the missing value is 32 or f(5) = 32.
For g(x) we can realize that each term is 10 more than the previous. This means g(5) = 40.
Perimeter of 30 ft in an area of 14 ft what is the length and the width
Answer:
14 and 1
Explanation:
14 + 14 + 1 + 1 = 30
14 x 1 = 14
The perimeter is the sum of all 4 sides. Divide the perimeter in half fo the some of one length and one width:
Length + width = 15
Area is length x width
Find 2 numbers that when added equal 15 but when multiplied equal 14
15 + 0 = 15, 15 x 0 = 0
14 + 1 = 15, 14 x 1 = 14
The answer is 14 ft long by 1 ft wide

[Help Asap, I will mark brainliest] In the figure below, g, || l. Find the values of y and x.
Answer:
x = 23
y = 110
Step-by-step explanation:
70 and 3x+1 are alternate exterior angles and that means they are equal
70 =3x+1
Subtract 1 from each side
69 = 3x
Divide by 3
69/3 =3x/3
23 =x
70 and y are same side exterior angles and that means they are supplementary ( add to 180)
70+y = 180
y = 180-70
y = 110
Matt thinks that he has a special relationship with the number 4. In particular, Matt thinks that he would roll a 4 with a fair 6-sided die more often than you'd expect by chance alone. Suppose pp is the true proportion of the time Matt will roll a 4.
Required:
a. State the null and alternative hypotheses for testing Matt's claim.
b. Now suppose Matt makes n = 46 rolls, and a 2 comes up 10 times out of the 46 rolls. Determine the P-value of the test.

2. Solve system A by substitution. Solve system B by elimination.
A. {
x = 3y − 4
2x − y = 2
B. {
3x + 2y = 7
−x + y = −4
Answer:
A. x = 2 and y =2
B. x = 3 and y = -1
Step-by-step explanation:
A. { x = 3y − 4
2x − y = 2
1) Substitute the value of x
2(3y − 4) − y = 2
2) Solve the equation for y
y = 2
3) Substitute the value of y
x= 3(2) -4
4) Solve the equation for x
x = 2
Final Solution: x = 2 and y =2
B. { 3x + 2y = 7
−x + y = −4
1) Multiply both sides of the equation by 3
-3x + 3y = -12
2) Eliminate one variable by adding the equations
3x + 2y = 7
+ (−3x + 3y = −12)
5y = -5
3) Divide both sides of the equation by 5
y = -1
4) Substitute the given value of y into the equation -x + y = -4
-x + (-1) = -4
5) Solve the equation for x
x = 3
Final Solution: x = 3 and y = -1

A manufacturer has determined that for every 1000 units it produces, 3 will be faulty. What is the probability that an order of 50 units will have one or more faulty units
Answer:
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.
Step-by-step explanation:
Mean for a number of units, which means that the Poisson distribution is used to solve this question.
Poisson Distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
Mean:
3 defective for 1000, how many for 50?
3 - 1000
[tex]\mu[/tex] - 50
Applying cross multiplication:
[tex]\mu = \frac{3*50}{1000} = 0.15[/tex]
What is the probability that an order of 50 units will have one or more faulty units?
This is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-0.15}*(0.15)^{0}}{(0)!} = 0.8607[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8607 = 0.1393[/tex]
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.

sure to select at least two values in the

interval 0 < x < 1.
2. How did you decide what values to use for x in your table?
3. How did you use the x values to find the y values in the table?
4. What similarities do you see in the graphs?
5. What differences do you observe in the graphs?
6. What is the effect of changing the base on the graph of a logarithmic function?
Answer:
pls edit the question. there seems to be missing information. the function are not there.
in the meantime I hive you as much as possible.
I'll edit when you gave the missing functions.
your table of values could look like this:
x y1 y2
-2
-1
0
0.25
0.5
1
2
3
4
5
2. I did choose some negative integers, some positive and, as the problem requested, 2 values between 0 and 1. this should give some idea of the function when graphed.
3. calculate each scenario by swapping the x in the formula with the value for x from the table.
4. [need the functions for this one, but probably: one has a steeper slope than the other one]
5. [definitely need the graphs for this. I'll graph dem for you then]
6. the common logarithm is to the base 10. that means it answers questions like
[tex] {10}^{x} = 100[/tex]
this would be 2 for the example, so
[tex] log(100) = 2[/tex]
[tex] log_{10}(100) = 2[/tex]
these two are the same
if we change the base to, let's say, 8, it gives answers to problems like
[tex] {8}^{x} = 64[/tex]
this is relatively easy to see 2, so we can write it this way:
[tex] log_{8}(64) = 2[/tex]
Generally speaking, the log asks to wich power some base has to be raised to equal as certain value, like eight to the power of what equals 64.
Twice the sum of a certain number and 26 is 72
Answer:

or,x=38-26
Therefore,x=12.
PLEASE HELP IM SO STUCK!
Answer:
x = 30
Step-by-step explanation:
The angle in the bottom right is 120
Call is y
y+60 = 180
y = 180-60
y =120
Opposite angles in a parallelogram are equal so the upper left angle is 120
Call the 3x +z = 120
We also know that 2x+90 +z = 180 since it forms a straight line
Subtract 90 from each side
2x+z = 90
Using 3x+z = 120 and 2x+z =90 and subtracting the second equation
3x+z = 120
-2x-z =-90
------------------
x = 30

Angel signed up for a streaming music service
that costs $11 per month. The service allows
Angel to listen to unlimited music, but if he
wants to download songs for offline listening, the
service charges $0.50 per song. How much total
money would Angel have to pay in a month in
which he downloaded 25 songs? How much
would he have to pay if he downloaded s songs?
Answer:
Cost for 25 songs: $23.50
Cost for s songs: .50(s) + 11
Step-by-step explanation:
To solve this problem, we can make an equation in slope-intercept form:
y = mx + b
y represents the total amount of $.
m represents the cost of each song downloaded, or $.50
x represents the number of songs, or 's'
b represents the $11, or the constant.
We have the equation:
y = .50(x) + 11
If Angel downloaded 25 songs, we have the equation:
y = .50(25) + 11
We get y = $23.50

The table below shows the probability distribution of student ages in a high school with 1500 students. What is the expected value for the age of a randomly chosen student? Age 13 14 15 16 17 18 Probability 0.01 0.27 0.30 0.25 0.16 0.01 O A. 15.38 OB. 15.31 O C. 15.50 D. 15.35 SUBNET
Answer:
According to me it should be Option B, 15.31
Hope this helps!
The expected value for the age of a randomly chosen student is,
⇒ 15.38
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that:
Total number of students,
⇒ n = 1500,
And, Age : 13, 14, 15, 16, 17, 18
Probability : 0.01, 0.25, 0.27, 0.30, 0.16, 0.01
Now,
We can Calculate the expected value as shown below,
E = 13 × 0.01 + 14 × 0.25 + 15 × 0.27 + 16 × 0.30 + 17 × 0.16 + 18 × 0.01
E = 0.13 + 3.5 + 4.05 + 4.8 + 2. 72 + 0.18
E = 15.38
Therefore, The expected value for the age of a randomly chosen student is 15.
