Answer:
500 + 200x = 3500 , 15 months
Step-by-step explanation:
starting 500
200 each month = 200x
Using a linear function, it is found that it will take Manny 15 months to save up the money for his car.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the initial deposit of $500 is the y-intercept, while the monthly deposit of $200 is the slope, hence the amount after n months is given by:
A(n) = 200n + 500.
The number of months it will take to get to $3500 is given by:
200n + 500 = 3500.
200n = 3000
n = 15.

During the clearance sale the store discounted all jewelry 1/4. What is the discount on a $19.96 bracelet
Answer: $4.99
Step-by-step explanation:
The store discounted all jewelry by 1/4 which means that they removed 1/4 of the price of an item off of it.
The discount on a $19.96 bracelet would therefore be:
= 1/4 * 19.96
= $4.99
This means that the item will sell for:
= 19.96 - 4.99
= $14.97

The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier
Answer:
Standardized z score = 2.06
His house rent is not an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score = 1390
μ is the population mean = 970
σ is the population standard deviation = 204
His z score is calculated as:
z = 1390 - 970/204
z = 2.06
No his house rent is not an outlier

A bear can run up to 18.47 feet per second. How many feet could the bear run in 3.9 seconds? 720.33 feet 7,203.3 feet 72.033 feet 7.2033 feet
Answer:
72.033 ft
Step-by-step explanation:
To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.
[tex]\frac{18.47}{1}=\frac{y}{3.9}[/tex]
Step 1: Switch sides
[tex]\frac{y}{3.9}=\frac{18.47}{1}[/tex]
Step 2: Apply rule: [tex]\frac{a}{1}=a[/tex]
[tex]\frac{y}{3.9}=18.47[/tex]
Step 3: Multiply both sides by [tex]3.9[/tex]
[tex]\frac{3.9y}{3.9}=18.47\cdot \:3.9[/tex]
Step 4: Simplify
[tex]y=72.033[/tex]
The bear can run 72.033 feet in 3.9 seconds
At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?
Answer:
ΔT = ( -19°C - 11°C) = -30°C
Step-by-step explanation:
When we have a given variable, let's call it X, the change of X in a given interval is written as:
ΔX = (X₂ - X₁)
Where:
X₂ = final value of the variable
X₁ = initial value of the variable.
In this case, we have the temperature, and we know that the initial temperature is 11°C, then:
T₁ = 11°C
While the final temperature is -19°C, then:
T₂ = -19°C
Then the change will be:
ΔT = ( -19°C - 11°C) = -30°C
This is the wanted expression.

Scott strikes out at bat 36% of the time. Find the probability that he strikes out no more than three times on his next eight times at bat.
Answer:
68.47%
Step-by-step explanation:
The answer is 68.47%
Solution -
We know that,
The binomial formula is -
P(x) = [tex]^{n}C_{x}p^{x}q^{n-x}[/tex]
where
n is the number of trials
x is the strike out number.
p is the probability of success
q is the probability of failure
Here,
n = 8
p = 36% = 0.36
q = 1 - 0.36 = 0.64
Now,
We want to find the probability that he strikes out no more than 3 times (i.e. <= 3.)
So,
We need to check the cases where x = 0, 1, 2 and 3.
Now,
For x = 0,
P(0) = [tex]^{8}C_{0}(0.36)^{0}(0.64)^{8-0}[/tex] = (0.64)⁸
P(1) = [tex]^{8}C_{1}(0.36)^{1}(0.64)^{8-1}[/tex] = 8×0.35×0.64⁷ .
P(2) = [tex]^{8}C_{2}(0.36)^{2}(0.64)^{8-2}[/tex] = 28×0.35² ×0.64⁶ .
P(3) = [tex]^{8}C_{3}(0.36)^{3}(0.64)^{8-3}[/tex] = 56×0.35³ ×0.64⁵ .
So,
Probability that he strikes out no more than three times = P(0) + P(1) + P(2) + P(3) = 68.47%

A number card numbered from 1 to 30
is drawn randomly.
What is the
probability of getting
a card having
the number divisible by 6 or 7?
Answer:
3/10
Step-by-step explanation:
We have to list out the numbers that are divisible by 6 and 7 that we can find between 1 and 30
so, we have this as;
6,7,12,14,18, 21, 24,28 and 30
The count we have here is 9
The total number we have is 30
So the probability is simply the count we have divided by 30
so we have this as ; 9/30 =
3/10

Answer:
x=4, y=-1. (4, -1).
Step-by-step explanation:
x+5y=-1
5x+15y=5
---------------
-5(x+5y)=-5(-1)
5x+15y=5
--------------------
-5x-25y=5
5x+15y=5
