Decide if each pair of triangles below is similar. If the triangles are similar, justify your conclusion by stating the similarity condition you used. Part 1
Answers
Answer:
a. AA
b. no (sides are not proportional)
Step-by-step explanation:
a. Two angles are marked as congruent. The triangles are similar by the AA postulate.
__
b. The side ratios 6 : 8 : 11 and 15 : 20 : 33 are both in reduced form. They are clearly not identical, so sides are not proportional. The triangles are not similar.

x = 12 − y
2x + 3y = 29
Answers
Bring the variables to one side and the constants to the other side of the equal sign. Remember if you bring anything to the other side it’s sign has to change:
x + y = 12
2x + 3y = 29
Now multiply a variable on the top equation so that it will be equal with the variable on the second:
3x + 3y = 36
2x + 3y = 29
Now subtract the equations which gets you:
x = 7
So we know what the x is, now we have to substitute the x in an equation we created; we’ll go with x + y = 12:
x + y = 12
= 7 + y = 12
Now bring the variable to one side and constants to the other like we did before (remember, the sign must change if the constant or variable is moved to different sides of the equal sign):
y = 12 - 7, which would equal y = 5.
So our answer would be:
( x, y ) = ( 7, 5 )
Hope this helps have an awesome day!

The weight of oranges growing in an orchard is normally distributed with a mean weight of 5.5 oz. and a standard deviation of 1 oz. Using the empirical rule, determine what interval would represent weights of the middle 68% of all oranges from this orchard.
pleaseeee help me now, im taking a test and it's timed
Answers
This is bevause 1 standard deviation contains 34% of the sample in a normal distribution, so 1 standard deviation on either side is 68% and so you +\- 1 oz from the mean.

If 20% of a school was made up of out-of-district students last year, but the number of out-of-district students increased by 50% this year, without any change in total enrollment, what percent of the students is out-of-district this year?
Answers
Answer:
30% is enrolled out-of-district.Step-by-step explanation:
According to the word problem, the number is increased by 50%.
To increase a number by a percent, multiply the number and the percent.
We can do this by changing both percents to decimals.
To change a percent to a decimal, divide it by 100.
[tex]20/100 = 0.2[/tex]
[tex]50/100=0.5[/tex]
The number is INCREASED by 50% so 0.5 would become 1.5.
[tex]0.2 * 1.5=0.3[/tex]
0.3 = 30%.The store had 520 customers this week and 780 customers last week. What is the percent of change for the 2 weeks and was it an increase or a decrease?

Find a polynomial f(x) of degree 5 that has the following zeros. 1, 8, -7, 5, -4. Leave your answer in factored form
Answers
Answer:
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)
Step-by-step explanation:
The zeros of the function are written in the form
f(x) = (x-a)(x-b)..... where the a,b are the zeros
f(x) = (x-1) (x-8) (x - -7)(x-5) ( x--4)
Rewriting
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)

A watercolor painting is 25 inches long by 12 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 3 inches to each side of the length and the width. What is the area of the mat?
Answers
Answer:
the area of the mat = total area added minus the original area of the water color painting.
Step-by-step explanation:
length of the mat is:L = 20 in + 1 in + 1 in because 1 in is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in
Area mat = (22 in x 11 in) - ( 20 in x 9 in)
area mat = 62 sq in is the area of the mat

x=-2 y=7
Step-by-step explanation:
Multiple -5 for the second equation to get -5x-20y=-130. Adding -5x-20y=-130 to 5x+y=-3 should get you -19y=-133. Divide both sides by -19 to get y=7. Subsitute 7 in for y for the first equation. Subtract 7 on both sides to get 5x=-10. Divide both sides by 5 to get x=-2. So, x=-2 and y=7.
Evaluating probability: A particular type of mouse's weights are normally distributed, with a mean of 726 grams and a standard deviation of 23 grams. If you pick one mouse at random, find the following: (round all probabilities to four decimal places) a) What is the probability that the mouse weighs less than 722 grams
Answers
Answer:
0.4325 = 43.25% probability that the mouse weighs less than 722 grams
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 of 726 grams and a standard deviation of 23 grams.
This means that [tex]\mu = 726, \sigma = 23[/tex]
a) What is the probability that the mouse weighs less than 722 grams
This is the p-value of Z when X = 722. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{722 - 726}{23}[/tex]
[tex]Z = -0.17[/tex]
[tex]Z = -0.17[/tex] has a p-value of 0.4325
0.4325 = 43.25% probability that the mouse weighs less than 722 grams
