Bananas FOR $1.00 Oranges - 6 FOR $1.50 Peaches - 4 for $1.28 Frankie mother tells Him that they need 5 Bananas 15 Oranges. And 10 peaches For the Salad. Determine the total cost of the amount of fruit that " FRAnkie needs.
Answers
Answer:
Mizuki is here to help! The answer will be $11.95
Step-by-step explanation:
Ok so... Frankie wants 5 bananas, 15 oranges, and 10 peaches for the salad right?
First, let's find the price of the 5 bananas. We multiply 1 by 5 and get 5, so $5 is the cost for the bananas he is going to spend.
Next, let's find the price for 15 oranges. First, we will divide 15 by 6, which will end up with 2.5. Then, we multiply 1.5 by 2.5 which will be 3.75. The price for the oranges he is going to buy is $3.75.
Then, let's find the price of the 10 peaches. The step is similar from the way we solved the price of oranges. We divide 10 by 4 and get 2.5. Next, we will multiply 1.28 by 2.5 and get 3.2. The price for peaches is $3.2.
Finally, let's add up 5, 3.75, and 3.2! The total should be 11.95! That will be your answer!

Fran is training for her first marathon, and she wants to know if there is a significant difference between the mean number of miles run each week by group runners and individual runners who are training for marathons. She interviews 38 randomly selected people who train in groups, and finds that they run a mean of 49.5 miles per week. Assume that the population standard deviation for group runners is known to be 1.1 miles per week. She also interviews a random sample of 33 people who train on their own and finds that they run a mean of 48.5 miles per week. Assume that the population standard deviation for people who run by themselves is 2.6 miles per week. Test the claim at the 0.01 level of significance. Let group runners training for marathons be Population 1 and let individual runners training for marathons be Population 2.
Required:
Draw a conclusion and interpret the decision.
Answers
Answer:
conclude that there is no significant evidence to support the claim that difference exists between the mean number of miles run by the two groups.
Step-by-step explanation:
H0 : μ1 = μ2
H0 : μ1 ≠ μ2
The test statistic :
(x1 - x2) / √(s1²/n1) + (s2²/n2)
(49.5 - 48.5) / √(1.1²/38) + (2.6²/33)
1 / √0.2366905
Test statistic = 2.055
Using the Pvalue from Tstatistic calculator :
df = (smaller sample - 1) = 33 - 1 = 32
Pvalue from Test score calculator = 0.048
Pvalue > α ; Fail to reject the null ;
Hence, conclude that there is no significant evidence to support the claim that difference exists between the mean number of miles run by the two groups.

12 pounds of corn cost Marcus $15.60. How much would five pounds of corn
cost at the same unit rate?
Answers
Answer:
$6.30
Step-by-step explanation:
Alright, so, to find the unit rate (how much 1 pound of corn would cost) you would divide $15.60 by 12 which would get you $1.30.
Cost of 1 pound of corn = $1.30
So the unit rate = $1.30
Now that you know the unit rate, or how much 1 pound would cost, you can find out how much 5 pounds would cost:
$1.30 x 5 = $6.50
Steps:
1. $15.60/12 = $1.30
2. $1.30 x 5 = $6.50
Five pounds of corn costs $6.50 at a unit rate of $1.30.

Draw a diagram of x + 2 and a separate diagram of 3x when x is 2.
Answers
The graph of the equation x + 2 would be a straight line that starts at the point (-2, 0) and goes up 2 units on the y-axis. So, the line would pass through the point (0,2) and would be parallel to the x-axis.
The graph of the equation 3x when x is 2 would be a straight line that starts at the point (0,0) and goes up 6 units on the y-axis for each 1 unit on the x-axis. So, the line would pass through the point (2,6) and would have a slope of 3.

Given ΔRST with:
sin ∠T = 1/5m ∠R = 30°r = 15t = ?Solution
We know t is opposite ∠T and r is opposite ∠R.
Use the law of sines to find the missing value of t.
r / sin ∠R = t / sin ∠TSubstitute the known values and solve for t:
15 / sin (30°) = t / (1/5)15 / (1/2) = 5t30 = 5tt = 30/5t = 6Answer:

(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Given:

[tex]\implies \sf \dfrac{r}{\sin R}=\dfrac{s}{\sin S}=\dfrac{t}{\sin T}[/tex]
[tex]\implies \sf \dfrac{15}{\sin 30^{\circ}}=\dfrac{t}{\frac{1}{5}}[/tex]

Consider the function f (x) = x.What effect does subtracting 2 from the input have on the graph of the function?
Answers
The effect of subtracting 2 from the input on the graph of the function is a translation of 2 units to the right.
What effect does subtracting 2 from the input?For any function f(x), we define a horizontal translation of N units as:
g(x) = f(x + N)
And what this does, is translate the graph N units horizontally.
if N > 0, then the translation is to the left.
if N < 0, then the translation is to the right.
Here we want to subtract 2 from the input, so we will get:

Match each expression with its given value.
Answers
The rate of change of surface area is 524.02 square kilometers per minutes.
what is surface area of square prism?The total space occupied by a three-dimensional square prism is called surface area.
What is the rate of change of surface area of the prism?
Given, the decreasing rate of the base side with respect to time, ds/dt = 7 km/min
the increasing rate of height with respect to time, dh/dt = 10 km/min
At a time, t, base side, s = 4 km
and height, h = 9 km
we need to determine the rate of change of surface area with respect to time, d A/dt
from the differentiation chain rule, d A/ dt = d A /dt × ds /ds
d A /dt = d A/ ds × ds /dt ... equation 1
we know that the surface area for prism, A = 2s² + 4sh
if we differentiate with respect to s then we find d A /ds
d/ds (A) = d/ ds (2s² + 4sh)
d A /ds = 4s + 4h +4s dh/ds ...... equation 2
now dh /ds = dh /ds × dt /dt [ using differentiation chain rule]
dh/ds = dh/ dt× dt/ds
d h/ ds = dh/dt × 1/ ds/dt
it stated earlier that dh/ dt = 10 and ds /dt = 7
dh / ds = 10/7
putting this value in equation 2, we get
d A /ds = 4s +4h + 4s ×10/7
as we know at time t, s= 4 and h = 9
d A /ds = 4 × 4 + 4 ×9 +4×4 ×10 /7
d A /ds = 74.86
putting the value d A /ds in equation 1, we get
d A /dt = d A /ds × ds/ dt
d A/ dt = 74.86 × 7
d A /dt = 524.02 km² / min
hence, the rate of change of surface area = 524.02 square kilometers per minutes

David is saving $250 to buy a bicycle. He saved $8 each week for 12 weeks. He wants to buy the bicycle in 7 more weeks. How much does David need to save each week?
Answers
Answer:
He would need to save $22 dollars each week to pay for the bike in 7 weeks.
Step-by-step explanation:
We can figure out how many he has saved up already by multiplying the number of weeks (12) by how much he saved each week ($8) which equals $96. Now we have to subtract $96 from $250 which equals $154. Now we need divide this amount by the remaining weeks until he wants to purchase his bike (7), so 154/7 which equals $22.
So he needs to pay 22 dollars each week to pay off the bike in seven weeks

Step-by-step explanation:
Given: 10, 8, 12, 15, 13, 11, 6, 5
c = 95%
a. The point estimate of the population mean is the sample mean. The mean is the sum of all values divided by the number of values:
x = 10 + 8 + 12 + 15 + 13 + 11 + 6 + 5 /8
= 80/8
= 10
b. The point estimate of the population standard deviation is the sample standard deviation. The variance is the sum of squared deviations from the mean divided by n - 1. The standard deviation is the square root of the variance:
s = /(10 – 10)^2 +.... + (5– 10)^2/8 – 1
s = 3.4641
c. Determine the t-value by looking in the row starting with degrees of freedom df = n-1 = 8 –1 = 7 and in the column with = (1 – c)/2 = 0.025 in table :
t_/2 = 2.365
The margin of error is then:

Bookerville has a record of 12 inches of rain in 5 days. How much will it have to rain on Friday to beat the record by one tenth of an inch
Answers
The amount of rain required would be 2.5 inches.
What is the addition?
Addition is a mathematical operation that represents the process of combining two or more numbers together. The result of this operation is called the sum. The addition operation is often represented using the symbol "+", and it can be used to add any two or more numbers together.
To beat the record by one-tenth of an inch, an additional 0.1 inches of rain must fall.
Currently, the average amount of rain per day is 12 inches / 5 days = 2.4 inches per day.
So, the amount of rain that must fall on Friday to beat the record by one-tenth of an inch is 2.4 inches + 0.1 inches = 2.5 inches
Hence, the amount of rain required would be 2.5 inches.
