Answer:
Deondra can buy 2 outfits.
Step-by-step explanation:
Since Deondra has $ 420 to spend at a bicycle store for some new gear and biking outfits, and she buys a new bicycle for $ 236.31, 2 bicycle reflectors for $ 3.07 each and a pair of bike gloves for $ 34.75, and she plans to spend some or all of the money she has left to buy new biking outfits for $ 59.50 each, to determine the number of outfits Deondra can purchase while staying within her budget the following calculation must be performed:
(420 - (236.31 + 2 x 3.07 + 34.75)) / 59.5 = X
(420 - (236.31 + 6.14 + 34.75)) / 59.5 = X
(420 - 277.2) / 59.5 = X
142.8 / 59.5 = X
2.4 = X
Therefore, Deondra can buy 2 outfits.

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

How much work is done lifting a 35 pound object from the ground to the top of a 25 foot building if the cable used weighs 2.5 pounds per foot
Answer:
3400 ft-lbs
Step-by-step explanation:
The Workdone in lifting the rope :
Number of feet = x
Distance = 25 feets
2.5x + 35
Taking the integral :
∫2.5x + 35 dx at x = 40
Integrating, we have :
1/2(2.5x² ) + 35x at x = 40
1/2(2.5(40)²) + 35(40)
1/2(4000) + 1400
2000 + 1400
= 3400
Hence, Workdone in lifting the rope = 3400 ft-lbs

The number line (d) represents the values of x that makes -3x + 1 < 7 to be true
How to determine the number line?The inequality is given as:
-3x + 1 < 7
Subtract 1 from both sides
-3x < 6
Divide both sides by -3
x > -2
This means that the number line must show an inequality that is greater than -2
From the list of options, the number line that represents x > -2 is (d)
Hence, the number line (d) represents the values of x that makes -3x + 1 < 7 to be true

A survey of 200 families showed that
75 had a dog;
58 had a cat;
25 had a dog and a cat;
77 had neither a cat nor a dog nor a parakeet;
5 had a cat and dog and a parakeet.
How many had a parakeet only?
Answer:
15 is the answer , the total people who has dogs , cats , parakeets and none is equals to 185 then from 200 you minus 185 which is 15 so 15 people had parakeets only

m = -28
m = -26
m = 26
m = 28
Answer:
[tex]m = - 28[/tex]
Step-by-step explanation:
[tex] \frac{ - 3}{7} m = 12[/tex]
[tex] \frac{ - 7}{3} ( \frac{ - 3}{7})m = \frac{ - 7}{3} \times 12[/tex]

[tex] - 1( - 1)m = \frac{ - 7}{3} \times 12[/tex]
[tex]1 \times m = \frac{ - 7}{3} \times 12[/tex]
[tex]m = \frac{ - 7}{3} \times 12[/tex]
[tex]m = \frac{ - 7}{3} \times 12[/tex]

Hope it is helpful....A bakery sells cakes, cookies, and pastries. They wonder if customers are equally likely to buy each product. They take a sample of 200 recent purchases and record what was purchased (they are willing to treat this as a random sample). Here are the results
Product Cakes Cookies Pastries
Observed purchases 65 68 67
They want to perform a x^2 goodness-of-fit test to determine if these results suggest that one type of product is more popular than the others. What is the expected count of cake purchases?
Answer:
66.667 cakes
Step-by-step explanation:
The expected count or value in a goodness of fit test is the product of the expected percentage and the total count or sample size.
Since the samples are being treated as a random sample, hence, the expected percentage of each of cake, pastries and cookies is the same.
The expected count of cakes is :
100/3 % * sample size
33.3333% * 200
= 66.667 cakes

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of bolts. The sample mean bolt length was centimeters. The population standard deviation is known to be centimeters.
What is the test statistic z?What is the p-value?Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of α=0.1?
Answer:
There is sufficient evidence. A further explanation is provided below.
Step-by-step explanation:
According to the question,
The alternative as well as null hypothesis will be:
[tex]H_0:\mu = 16[/tex]
[tex]H_a:\mu>16[/tex]
The test statistics will be:
⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]
By putting the values, we get
⇒ [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]
⇒ [tex]=2.45[/tex]
Or,
The p-value will be:
= 0.0071
i.e.,
⇒ [tex]p-value< \alpha[/tex]
Thus the above is the correct answer.

Answer:
6 1/4
Step-by-step explanation:
When you look at the bar graph at the top, you will see that there are 5 of 1 1/4.
If you multiply 5 by 5/4 (which is 1 1/4 converted to an improper fraction), you get 25/4. To convert that to a mixed number, divide 25 by 4 and put the remainder over 4. The final answer should be 6 1/4.
For the X's, just count how many of each number is in the graph above. For example, there should be 2 X's over 1, 5 X's over 1 1/4, 2 X's over 1 1/2, and 2 X's over 1 3/4.
