Susan needs to buy apples and oranges to make fruit salad. She needs 15 fruits in all. Apples cost $3 per piece, and oranges cost $2 per piece. Let m represent the number of apples. Identify an expression that represents the amount Susan spent on the fruits. Then identify the amount she spent if she bought 6 apples. 30 + 5m; $36 30 + m; $36 30 + 5m; $24 30 + m; $24
Answer:
m + 30 ; $36
Step-by-step explanation:
Given that:
Total fruits needed = 15
Fruits needed :
Apple (m) ; cost = $3 per piece
Oranges (o) ; cost = $2 per piece
Amount spent on fruits :
[(cost of apple * number of apples) + (cost of orange *(total fruits - number of apples)]
3m + 2(15 - m)
3m + 30 - 2m
3m - 2m + 30
m + 30
Amount spent if 6 apples is purchased :
m = 6
m + 30
6 + 30 = $36

Explain how to estimate the product of 12/3/8 times 6/7/8.
Answer:
210 approximately.
Step-by-step explanation:
12/3/8 = 12*8/3 = 32
6/7/8 = 6*8/7 = 48/7 = 7 approximately
So the product is approximately 30*7 = 210.
Denise is going to shop with the $250.00 that she earned from doing chores. She wants to save
20% of her money to put into a savings account. She buys a pair of jeans for $75.00 and a new
leather coat for $110.00, with 5% sales tax on both items. Does Denise still have the amount of
money she planned to put into her savings account?
Yes she does.
I just answered the question.
Three assembly lines Alpha, Beta, and Gamma make the same power transistor. Each of the assembly lines has its own level of efficiency. Resulting in inventory having 20% of the transistors from Alpha, 50% from Beta, and the remaining 30% from Gamma. Further the probability a transistor from Alpha will be defective is 0.02, a transistor from Beta will be defective is 0.06, and a transistor from Gamma will be defective is 0.04. If a random transistor from inventory is defective, what is the probability it came from Bet
Answer:
P [ β / Def] = 0,6521 or 65,21 %
Step-by-step explanation:
Tree diagram:
0,20 (α) Defective 0,02
0,50 (β) defective 0,06
0,30 (γ) defective 0,04
According to Baye´s Theorem
P [ A/B] = P[A] * P [ B/A] / P[B]
if we call
β = A and Defective = B then P[β] = P[A] and P[Defective] = P[B]
we get :
P [ β / Def] = P[β] * P [ def./β] / P[def]
Then
P[β] = 0,5
P[def/β] = 0,06
P [Defective] = 0,02* 0,2 + 0,06*0,5 + 0,04*0,3
P [Defective] = 0,004 + 0,03 + 0,012
P [Defective] = 0,046
P [ β / Def] = 0,5 * 0,06 / 0,046
P [ β / Def] = 0,6521 or 65,21 %

Answer:
[tex]y = \frac{1}{3}x +2[/tex]
Step-by-step explanation:
Given
Equation:
[tex]y = \frac{1}{3}x + 4[/tex]
[tex]Point: (-3,1)[/tex]
Required
Determine the equation of the point parallel to the given equation
First, we need to determine the slope of: [tex]y = \frac{1}{3}x + 4[/tex] using
[tex]y = mx + b[/tex]
Where m represents slope.
By comparison
[tex]m = \frac{1}{3}[/tex]
The equation of the point is calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
Where [tex](x_1,y_1) = (-3,1)[/tex]
So, we have:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = \frac{1}{3}(x - (-3))[/tex]
[tex]y - 1 = \frac{1}{3}(x +3)[/tex]
[tex]y - 1 = \frac{1}{3}x +1[/tex]
Solve for y
[tex]y = \frac{1}{3}x +1 +1[/tex]
[tex]y = \frac{1}{3}x +2[/tex]
What are the two decisions that you can make from performing a hypothesis test? Select all that apply.
A.
accept the alternative hypothesis
B.
fail to reject the alternative hypothesis
C.
accept the null hypothesis
D.
fail to reject the null hypothesis
E.
reject the null hypothesis
F.
reject the alternative hypothesis
G.
make a type II error
H.
make a type I error
Answer:
reject the null hypothesis or fail to reject the null hypothesis.
The two decisions that perform the hypothesis test includes fail to deny the null hypothesis, and deny the null hypothesis.
Hypothesis testing refers to the testing that can give access to the reliability of the hypothesis via sample data.
There are two types of decisions that are considered to be wrong while performing the hypothesis test is:
In the case when the hypothesis is true but i.e. rejected. This is known as a type I error.In the case when the hypothesis is false, but it is failed to reject it. This is known as a type II error.So, the decisions that should not be considered while performing the hypothesis test is:
Acceptance of the alternative hypothesis.Acceptance of the null hypothesis.Fail to deny the alternative hypothesis.Deny the alternative hypothesis.Making of type I error.Making of type II error.Therefore we can conclude that options D and option E are considered from performing a hypothesis test.

2y-5y=-10.
what are the x and y intercepts
Answer:
The y intercept is (0,2) and the x intercept is (5,0)
Step-by-step explanation:
Find the y-intercept by letting x = 0
2(0) + 5y = 10
5y = 10
y = 2 Therefore, the y-intercept is (0, 2)
Find the x-intercept by letting y = 0
2x + 5(0) = 10
2x = 10
x = 5 Therefore, the x-intercept is (5, 0)

The cost of parking a motor home in a state park includes a one time fee of $180, plus a daily rate of $55 per day. Anthony prepaid for his stay and paid the state park commission a fee of $565. This paid for the one time fee as well as for a number of days. How many days of parking did Anthony pay for? Group of answer choices
Answer:
Anthony paid for 7 days of parking.
Step-by-step explanation:
From the information given, the cost of parking a motor home in a state park would be equal to the one time fee plus the result of multiplying the daily rate for the number of days:
c=180+55x, where c is the cost of parking the motor home and x is the number of days.
Now, you can replace c with 565 that is the amount Anthony prepaid and you can solve for x to be able to find the number of days he paid for:
565=180+55x
565-180=55x
385=55x
x=385/55
x=7
According to this, Anthony paid for 7 days of parking.

No. He multiplied the denominators instead of finding a common denominator.
No. He multiplied with the reciprocal of the dividend instead of with the reciprocal of the divisor.
Answer:
(d) No. He multiplied with the reciprocal of the dividend instead of with the reciprocal of the divisor.

Angela earns $11.50 per hour. If she works more than 40 hours a week she earns double time. This week she worked a total of 48 hours. How much was her total weekly paycheck?
Answer:
11.50 x 40 regular hours is $460
double time is 11.50 x 2 = $23 an hour
She makes $23 an hour for 8 hours = $184
$460 + $184 = $644 paycheck

-2/3x^2-1=17 can y'all help me please !!!
The answer is ±3[tex]\sqrt{3\\}[/tex]
First, you should make one side of the quadratic 0. You can do this by subtracting 17 from both sides, making the equation
2/3x^2 - 18 = 0
To make everything an integer, you can multiply both sides by 3/2, making the equation
x^2 - 27 = 0
By adding 27 to both sides, you get
x^2 = 27
Now you are practically done! By taking the square root of both sides, you get
x = ±3[tex]\sqrt{3\\}[/tex]

The GCF of two numbers is equal to the lesser of the numbers? Always,sometimes, or never true
Answer:
Sometimes
Step-by-step explanation:
To answer this question, I'll make use of the following illustrations:
GCF of 4 and 10
[tex]4 = 1 * 2 * 2[/tex]
[tex]10 = 1 * 2 * 5[/tex]
Hence:
The GCF is
[tex]GCF = 1 * 2[/tex]
[tex]GCF = 2[/tex]
GCF of 5 and 10
[tex]5 = 1 * 5[/tex]
[tex]10 = 1 * 2 * 5[/tex]
[tex]GCF = 1 * 5[/tex]
[tex]GCF = 5[/tex]
In the first scenario, the GCF is lesser than the smallest number.
In the second, the GCF is equal to the smaller number.
Hence:
The option that completes the question is "sometimes"
