Hey there!
“x – 3 < 2”
Let’s change your current question into a(n) equation to make it EASIER to solve (this is for temporary purposes ONLY)
• Temporary question
x – 3 = 2
• First: ADD BOTH SIDES by 3
x – 3 + 3 = 2 + 3
• CANCEL: –3 + 3 because that gives you 0
• KEEP: 2 + 3 because that helps solve for x
• New temporary question: 2 + 3 = x
2 + 3 = 5
The temporary question answer is: x = 5 ✅
NOW LETS SOLVE FOR YOUR ACTUAL EQUATION (just saying it REQUIRES the SAME steps as the temporary question just a TAD bit differently!)
x – 3 < 2
• FIRST: ADD both SIDES BY 3
x – 3 + 3 < 2 + 3
• CANCEL: –3 + 3 because that gives you 0
• KEEP: 2 + 3 because that helps us compare the answer with x
• New equation: x < 2 + 3
2 + 3 = 5
x < 5
Answer to your given question is: x < 5 ☑️

Answer:
15 units
Step-by-step explanation:
UW is the midsegment of ΔVXY,
By midsegment theorem of a triangle,
"Segment joining the midpoints of two sides of a triangle is parallel to the third side and measure of midsegment is half of the length of the third side."
UW = [tex]\frac{1}{2}(XY)[/tex]
Since, XY = 30 units
UW = [tex]\frac{1}{2}(30)[/tex]
= 15 units
Therefore, length of the midsegment UW = 15 units will be the answer.

Customers arrive at a movie theater at the advertised movie time only to find that they have to sit through several previews and prepreview ads before the movie starts. Many complain that the time devoted to previews is too long. A preliminary sample conducted by The Wall Street Journal showed that the standard deviation of the amount of time devoted to previews was five minutes. Use that as a planning value for the standard deviation in answering the following questions.a. If we want to estimate the population mean time for previews at movie theaters with a margin of error of 78 seconds, what sample size should be used
Answer:
57
Step-by-step explanation:
Given that :
Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds
Margin of Error, E = 78
Assume a confidence interval of 95%;
Using the relation :
((Zα/2 * σ) / E)²
(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025
Z0.025 = 1.96
Sample size = ((1.96 * 300) / 78)²
Sample size = (588 / 78)^2
Sample size = 7.5384615^2
Sample size = 56.828
= 57 samples
The amount of time needed for a certain machine to process a job is a random variable with mean EXi = 10 minutes and Var(Xi)=2 minutes2. The times needed for different jobs are independent from each other. Find the probability that the machine processes less than or equal to 40jobs in 7hours.
Answer:
0.98732
Step-by-step explanation:
Given that :
Mean = 10 minutes
Variance = 2 minutes
For less than equal 40 jobs
Mean (m) = 40 * 10 = 400 minutes
Variance = 2 * 40 = 80 minutes
Standard deviation (s) = √variance = √80
Converting hours to minutes
X = 60 * 7 = 420 minutes
P(X≤ 420) :
Z = (x - m) / s
P(X≤ 420) :
Z = (420 - 400) / √80
Z = 20 / √80 = 20 / 8.9442 = 2.236
P(Z ≤ 2.236) = 0.98732
The probability that the machine processes less than or equal should be 0.98732
Calculation of the probability:
Since
Mean = 10 minutes
Variance = 2 minutes
For less than equal 40 jobs
Mean (m) = 40 ( 10) = 400 minutes
Variance = 2 (40) = 80 minutes
Now
Standard deviation (s) = √variance = √80
Now here we Converting hours to minutes
So,
X = 60 (7) = 420 minutes
Now
P(X≤ 420) :
Z = (x - m) / s
Z = (420 - 400) / √80
Z = 20 / √80
= 20 / 8.9442
= 2.236
Now finally
P(Z ≤ 2.236)
= 0.98732
Hence, The probability that the machine processes less than or equal should be 0.98732

the sum of allmultiples of 6 between 10 & 87 is equal to
The sum of all multiples of 6 between 12 and 87 is equal to 624.
How to get the sum?
The multiples of 6 are of the form: 6*n
Where n is an integer.
The multiples between 10 and 87 are:
6*2 = 12
6*3 = 13
...
6*14 = 84
Then the sum of all these multiples can be written as:
[tex]6*2 + 6*3 + 6*4 + ... + 6*14\\\\= 6*(2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14) = 624[/tex]

How many ways are there to choose five doughnuts if there are eight varieties (and only the type of each doughnut matters)?
Answer:
There are 56 ways to choose 5 from 8 varieties.
Step-by-step explanation:
a) Choosing 5 out of 8
This is a combination problem, given by the formula below:
C(n,r)=?
C(n,r)=C(8,5)
=8!/(5!(8−5)!)
= 56
b) A combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed. The result of this combination of 5 out of 8 varieties shows that there 56 ways one can choose. The formula is given by 8 factorial divided by (5 factorial by 3 factorial).
7. The ratio of strawberries to grapes in the fruit salad is 3:9. The ratios of strawberries to honeydew is 6:14. If there 36 grapes, how peony strawberries. Match the fractions that are equivalent to each other
Answer:
12 strawberries
Step-by-step explanation:
Let
[tex]S = Strawberry[/tex]
[tex]G = Grape[/tex]
[tex]H = honeydew[/tex]
Given
[tex]S : G = 3 : 9[/tex]
S : H = 6 : 14
Required
Solve for S when G = 36
To do this, we make use of the first ratio
[tex]S : G = 3 : 9[/tex]
Substitute 36 for G
[tex]S : 36 = 3 : 9[/tex]
Convert ratio to fractions
[tex]\frac{S}{36} = \frac{3}{9}[/tex]
[tex]\frac{S}{36} = \frac{1}{3}[/tex]
Cross Multiply
[tex]S * 3 = 36 * 1[/tex]
[tex]3S = 36[/tex]
Divide through by 3
[tex]\frac{3S}{3} = \frac{36}{3}[/tex]
[tex]S = \frac{36}{3}[/tex]
[tex]S = 12[/tex]
The (b) part of the question can not be solved with the given details.
However, some equivalent fractions are:

[tex]\frac{5}{15} = \frac{10}{30}[/tex] --- 0.33
[tex]\frac{4}{7} = \frac{8}{14}[/tex] --- 0.57
To get the equivalent fractions, you have to convert the fractions to decimal and then make comparison.
