The line plot shows the amount of grass seed that a landscaper needs for each of her jobs. What is the total amount of grass seed that the landscape needs?
Answer:
[tex]Total = 18\frac{1}{4}[/tex]
Step-by-step explanation:
Given
The attached line plot
Required
The total
To do this, we simply multiply each grass seed by the frequency (i.e. number of dots), then add up the results.
So, we have:
[tex]Total = \frac{1}{4} * 2 + \frac{1}{2} * 3 + \frac{3}{4} * 1 + 1 * 2 + 1\frac{1}{4} * 1 + 1\frac{1}{2} * 3 + 1\frac{3}{4} * 1 + 2 * 3[/tex]
[tex]Total = \frac{1}{2} + \frac{3}{2}+ \frac{3}{4} + 2 + 1\frac{1}{4} * 1 + 1\frac{1}{2} * 3 + 1\frac{3}{4} * 1 + 2 * 3[/tex]
Convert fractions to improper fraction
[tex]Total = \frac{1}{2} + \frac{3}{2}+ \frac{3}{4} + 2 + \frac{5}{4} * 1 + \frac{3}{2} * 3 + \frac{7}{4} * 1 + 6[/tex]
[tex]Total = \frac{1}{2} + \frac{3}{2}+ \frac{3}{4} + 2 + \frac{5}{4} + \frac{9}{2} + \frac{7}{4} + 6[/tex]
Add fractions
[tex]Total = 18\frac{1}{4}[/tex]
Hence, the total amount is: [tex]18\frac{1}{4}\b[/tex] pounds

Answer:
yes
Step-by-step explanation:
7.8 x c + 3.4 = 19
7.8c + 3.4 = 19
7.8c = 19 - 3.4
7.8c = 15.6 (now divide both sides by 7.8)

A father is questioning the probability his daughter will receive a scholarship. She is a finalist for two different scholarships. The awarding of these scholarships is independent. For the first scholarship (Scholarship A) there are 5 finalists and two scholarships will be awarded. For the second scholarship (Scholarship B) there are also five finalists and one scholarship will be awarded.
1. What is the probability that she will receive Scholarship A and Scholarship B?
2. What is the probability that she will receive at least one scholarship, Scholarship A or Scholarship B?
3. Should she apply for both scholarships or one of the scholarships? If just one, which one? Why?
Solution :
According to the question, let
A : winning first scholarship
B : winning second scholarship
So for the first scholarship, there are five finalist and only two scholarship will be awarded. And for the second scholarship there are five finalist and only one scholarship will be awarded.
Therefore,
[tex]$P(A)=\frac{2}{5}$[/tex] and [tex]$P(B)=\frac{1}{5}$[/tex]
1. So, [tex]$P(A \cap B ) = P(A) P(B)$[/tex]
[tex]$=\frac{2}{5} \times \frac{1}{5}$[/tex]
[tex]$=\frac{2}{25}$[/tex]
2. [tex]$P(A \cup B) = P(A)+P(B)-P(A)P(B)$[/tex]
[tex]$=\frac{2}{5}+\frac{1}{5}-\frac{2}{25}$[/tex]
[tex]$=\frac{13}{25}$[/tex]
3. She should apply to both the scholarships, so as to have a maximum chances of winning at least one scholarship.

What is the area of the triangle?
Z - ( -7 ) < 5 it’s solving inequalities. Help. Also 8(3g - 2) <= 12(2g + 1) pls ;-;
Answer:
z < -2
g is indeterminate
Step-by-step explanation:
For the inequality Z - ( -7 ) < 5
open the parenthesis
z+7 < 5
Subtract 7 from both sides
z+7-7 < 5-7
z < -2
For 8(3g - 2) <= 12(2g + 1)
Expand
24g -16 ≤ 24g + 12
24g - 24g ≤ 12+18
0g≤ 28
g ≤ 28/0
Hence g is indeterminate
What is the probability of rolling the following number situation with a fair number cube (1-6)?
Odd number
Answer:
1/2, or 50%
Step-by-step explanation:
out of the six possibilities, there are 3 odd numbers: 1, 3, 5
3 out of 6 is 1/2, therefore the probability is 1/2, or 50%

below are two parallel lines with a third line intersecting them
Answer:
x = 122
Step-by-step explanation:
x = 122 because of alternate interior angles
Answer:
x = 122°
Step-by-step explanation:
Two parallel lines with a third line intersecting them are called a transversal.
The two angles shown in the picture, x and 122° are alternate interior angles.
Alternate angles are a pair of angles that are on the inner side of each of the two lines but are on opposite sides of a transversal.
These are really similar to vertically opposite angles!
All alternate angles have the same value, thus x = 122°.
You can also see that alternate angles are like corresponding angles and vertically opposite angles combined!

Answer:
Least value: s + r
Greatest value: s - r
Closest to zero: s
Step-by-step explanation:
Here, we can approximate r as -6 and s as 2.
If we calculate each possibility using our approximations above:
s - r = 2 - (-6) = 8
s = 2
s + r = 2 - 6 = -4
Using these numbers, we can conclude:
Least value: s + r
Greatest value: s - r
Closest to zero: s
Answer:
Least value: s + r
Greatest value: s - r
Closest to zero: s

Suppose that you work for Chick-fil-A and your manager has asked you to look at the wait times in the Drive-Thru. Supposing that wait times are normally distributed with a mean wait time of 30 seconds and a population standard deviation of 5 seconds. What is the probability that a randomly selected person will wait more than 42 seconds
Answer:
0.0082 = 0.82% probability that a randomly selected person will wait more than 42 seconds.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean wait time of 30 seconds and a population standard deviation of 5 seconds.
This means that [tex]\mu = 30, \sigma = 5[/tex]
What is the probability that a randomly selected person will wait more than 42 seconds?
This is 1 subtracted by the pvalue of Z when X = 42. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{42 - 30}{5}[/tex]
[tex]Z = 2.4[/tex]
[tex]Z = 2.4[/tex] has a pvalue of 0.9918
1 - 0.9918 = 0.0082
0.0082 = 0.82% probability that a randomly selected person will wait more than 42 seconds.
