A store is having a sale on jelly beans and almonds. For 5 pounds of jelly beans and 3 pounds of almonds, the total cost is $13. For 2 pounds of jelly beans and 6 pounds of almonds, the total cost is $16. Find the cost for each pound of jelly beans and each pound of almonds.
Answer:
The cost for each pound of jelly beans and each pound of almonds is $1.25 and $2.25 respectively.
Step-by-step explanation:
Let the cost for each pound of jelly beans and each pound of almonds be x and y respectively.
ATQ,
For 5 pounds of jelly beans and 3 pounds of almonds, the total cost is $13.
5x+3y = 13 ...(1)
For 2 pounds of jelly beans and 6 pounds of almonds, the total cost is $16.
2x+6y = 16
x + 3y = 8 ....(2)
Subtract equation (2) from (1)
5x+3y-(x + 3y)= 13-8
4x = 5
x = 5/4
x = $1.25
Put the value of x in equation (2) as follows :
1.25 + 3y = 8
3y = 8-1.25
y =$2.25
Hence, the cost for each pound of jelly beans and each pound of almonds is $1.25 and $2.25 respectively.

A golfer wants to determine if the type of driver she uses each year can be used to predict the amount of improvement in her game. Which variable would be the explanatory variable?a. The type of driverb. The number of holes she playsc. The rating of the golferd. The improvement in her game
Answer:
The type of driver
Step-by-step explanation:
The term known as '' response variable'' is use in describing a variable that changes when you alter an examination or a test. Just like its name implies, it is the ''response'' that one gets when the other variable that is the Explanatory Variable are being altered.
In this question, the golfer will have to be changing the type of drivers that she is using in order to be able to know whether these changes in drivers will increase her game performance. Hence, the Explanatory Variable is the type of driver in which the golfer changes which is being use to define the performance of the golfer.
Find the center and radius of
x2 + y2 + 2x – 10y + 10 = 0
x^2 + y^2 + 2x – 10y + 10 = 0
x^2 + 2x + y^2 - 10y = 0
We must complete the square in x and y.
(x^2 + 2x + 1) + (y^2 -10y + 25) = 4 + 25
(x + 1)^2 + (y - 5)^2 = 29
The radius r is found solving r^2 = 29 for y.
(x + 1)^2 + (y - 5)^2 = sqrt{29}
See picture for the center and radius.

Answer:
101.6 feet
Step-by-step explanation:
First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2
The perimeter of the four other windows: (3.6+4.8)*2=16.8
The total number of feet needed for the first two windows:
17.2*2 = 34.4 feet
The total number of feet needed for the four windows:
16.8*4 = 67.2 feet
The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.

Santa gave kittens to 13 boys and girls. What is the ratio of kitten ears to kitten tails?
Answer:
[tex]Ratio = 2 : 1[/tex]
Step-by-step explanation:
Given
[tex]Population = 13[/tex] --- Boys & Girls
Required
Determine the ratio of the kitten ears to the tails
A kitten has 1 tail and 2 ears.
Assume each individual got 1 kitten each
This implies that,
[tex]Number\ of\ tails= 1 * 13[/tex]
[tex]Number\ of\ tails= 13[/tex]
[tex]Number\ of\ ears= 2* 13[/tex]
[tex]Number\ of\ ears= 26[/tex]
The ratio of ears to tail is then calculated as follows:
Ratio = Number of ears : Number of tails
This gives
[tex]Ratio = 26 : 13[/tex]
Divide by 13
[tex]Ratio = 26/13 : 13/13[/tex]
[tex]Ratio = 2 : 1[/tex]
Determine whether a triangle can be formed with side lengths 8,11,5?
Answer:
Yes, a triangle can be formed
Step-by-step explanation:
Look
a=5
b=8
c=11
The rule is U need to add the 2 smallest sides
a+b>c
if a+b=c then this is not a triangle
Now look
5+8=13
13 is greater than 11
13>11 so this is a triangle
2 smallest sides are greater than biggest side

Answer:
[tex]f(0) = 14[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \left \{ {{|x - 8| + 6 \ x<4} \atop {15\ x\ge 4}} \right.[/tex]
Required
Find f(0)
From the piecewise function, we have the following as values of f(x):
[tex]f(x) = |x - 8| + 6[/tex]
If [tex]x < 4[/tex]
[tex]f(x) = 15[/tex]
If [tex]x \ge 4\\[/tex]
f(0) implies that [tex]x =0[/tex] and [tex]0<4[/tex]
So, we make use of the first function, which is:
[tex]f(x) = |x - 8| + 6[/tex]
Substitute 0 for x in [tex]f(x) = |x - 8| + 6[/tex]
[tex]f(0) = |0 - 8| + 6[/tex]
[tex]f(0) = |- 8| + 6[/tex]
[tex]|-8| = 8[/tex]
So, the expression becomes
[tex]f(0) = 8 + 6[/tex]
[tex]f(0) = 14[/tex]
Hence, the value of f(0) is 14

A researcher records the repair cost for 27 randomly selected refrigerators. A sample mean of $60.52 and standard deviation of $23.29 are subsequently computed. Determine the 90% confidence interval for the mean repair cost for the refrigerators. Assume the population is approximately normal.
Answer:
53.15≤x≤67.89
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar±(z×s/√n)
xbar is the sample mean
z is the z score at 90% CI
s is the standard deviation
n is the sample size
Given
xbar = $60.52
s = $23.29
n = 27
z = 1.645
Substitute into the formula
CI = xbar±(z×s/√n)
CI = 60.52±(1.645×23.29/√27)
CI = 60.52±(1.645×23.29/5.196)
CI = 60.52±(1.645×4.482)
CI = 60.52±7.373
CI = [60.52-7.373, 60.52+7.373]
CI = [53.15, 67.89]
Hence the 90% confidence interval for the mean repair cost for the refrigerators is 53.15≤x≤67.89

As the PR director you have a $65,000 annual budget. It's the end of June, and you have steadily spent 1/12 of the budget each month so far. But you just had to spend an extra $6,000 in June on crisis management. For the last six months of the year, what will be your adjusted monthly PR budget?
Answer:
$4,417
Step-by-step explanation:
$4,417
The adjusted monthly PR budget for last six months of the year is $4417.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Annual budget of PR director = $65,000
Monthly spent = [tex]\frac{65000}{12}[/tex]
⇒ [tex]5416.66[/tex] ≈ [tex]\$5417[/tex]
Last month had to spend an extra amount = $6,000
Thus adjusted monthly PR budget for last 6 months is
⇒ [tex]5417-\frac{6000}{6}[/tex]
⇒ [tex]5417-1000[/tex]
⇒ [tex]\$4417[/tex]
Hence we can conclude that the adjusted monthly PR budget for last six months of the year is $4417.

The results of a test that follows a normal distribution have a mean value of 10.0 and a standard deviation of 1.
Find the probability that a single reading is between 8 and 10
Answer:
The value is [tex]P(8 < X < 10 ) = 0.8186[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 10 .0[/tex]
The standard deviation is [tex]\sigma = 1[/tex]
Generally the probability that a single reading is between 8 and 10 is mathematically represented as
[tex]P(8 < X < 10 ) = P( \frac{8 - 10 }{ 1} < \frac{X - \mu }{ \sigma } < \frac{10 - 10 }{1} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(8 < X < 10 ) = P( -2 < Z< 1 )[/tex]
=> [tex]P(8 < X < 10 ) = P( Z< 1 ) - P( Z < -2 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1 and -2 is
[tex]P( Z< 1 ) = 0.84134[/tex]
and
[tex]P( Z < -2 ) = 0.02275[/tex]
=> [tex]P(8 < X < 10 ) = 0.84134 - 0.02275[/tex]
=> [tex]P(8 < X < 10 ) = 0.8186[/tex]

Brain enjoys hang gliding on his last flight, he jumped off a cliff 520 high he landed 450 from the base of the cliff how far did brain travel?
Answer:
Brain travelled 687.68 from the cliff.
Step-by-step explanation:
Given that:
Height of the cliff = 520
Base of the cliff = 450
The distance will form the hypotenuse of right angled triangle.
Pythagorean theorem states square of hypotenuse of right angled triangle is equal to the sum of squares of base and height of triangle.
Using pythagorean theorem;
a = 520, b=450, c = hypotenuse
[tex]a^2+b^2=c^2\\(520)^2+(450)^2=c^2\\270400+202500=c^2\\472900=c^2\\c^2=472900[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{472900}\\c=687.68[/tex]
Hence,
Brain travelled 687.68 from the cliff.

A researcher's measure of species diversity is made from water samples taken from two independent locations. The research finds the 95% confidence interval for the difference between species diversity in the two locations to be 0.223 space less than space mu subscript 1 minus mu subscript 2 less than 1.361. Based on part the researcher's confidence interval, is it reasonable to conclude that species diversity in location 1 is greater than species diversity in location 2
Answer:
It is reasonable to conclude that species diversity in location 1 is greater than species diversity in location 2.
Step-by-step explanation:
From the question we are told that
The 95% confidence interval for the difference between species diversity in the two locations is [tex]0.223 < \mu_1 - \mu_2 < 1.361[/tex]
Now this 95% confidence interval tell us that there a 95% confidence that the true difference between species diversity in the two locations is within the interval
For the value of the 95% confidence interval given we see that both the upper limit and the lower limit is greater than zero which tell us that the true difference will also be greater than zero
Hence
it is reasonable to conclude that species diversity in location 1 is greater than species diversity in location 2
