Any one know how to do this ? 1 through 4
Answers
Answer:
1. U = 54 T = 72
2. M = 76 N = 76
3. F = 134 EF = 18
4. P = 60 Q = 60 R = 60
Step-by-step explanation:
1. the triangle given is an isosceles triangle. this means that the two angles that aren't connected with a congruent side, have the same measures. These angles are also called base angles
in this case, those two angles are S and U
since we know S is 54, U will also be 54
to find the third angle, add all your know angles, then subtract it from 180. We do this because all the angles in a triangle will always add up to 180.
180 - (54 + 54) = 72
U = 54
T = 72
2. In this case M and N are your base angles. We know that the base angles are equal, and that when you add them with L, you should get 180.
we can start by subtracting L from 180 to find the sum of M and N
180 - 28 = 152
now divide this by 2 to find the individual angles:
152 / 2 = 76
so: M = 76 and N = 76
3. For this one, we can do something similar to what we did in question 1 to find F. Just add the base angle, and subtract it from 180 to find the third angle:
180 - (23 + 23) = 134
In isosceles triangles, there are two lines that are congruent, these two lines are the lines that meet at the abnormal angle. In this case, GF and EF are those lines.
so if GF is 18, then EF is also 18
4. This triangle is an equilateral triangle. This means that all sides and angles are congruent. to find the angles, all we have to do is divide 180 by 3, since there are 3 equal angles.
180 / 3 = 60
every angle is 60
A sample of 14001400 computer chips revealed that 311% of the chips do not fail in the first 10001000 hours of their use. The company's promotional literature claimed that more than 28(% do not fail in the first 10001000 hours of their use. Is there sufficient evidence at the 0.050.05 level to support the company's claim
Answers
Answer:
There is sufficient evidence at 0.05 significant level to support company's claim.
Step-by-step explanation:
We have these informations from the question
n = 1400
P^ = 31% = 0.31
Alpha level = 5% = 0.05
Then we come up with the hypothesis
H0: P = 0.28
H1: P>0.28
From here we calculate the test statistic
z = p^ - p/√pq/n
P = 0.28
q = 1-0.28
= 0.72
z = 0.31-0.28/√(0.31*0.72)/1400
= 0.03/√0.0001594
= 0.03/0.012
= 2.5
Then we have a p value = 0.00621
The p value is less than significance level
0.00621<0.05
So the null hypothesis is rejected.
We conclude that There is sufficient evidence at 0.05 significant level to support company's claim.

The value of x is -2 and 2.
Step-by-step explanation:
When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :
x² - 3x - 1 = -3x + 3
x² - 3x - 1 + 3x - 3 = 0
x² - 4 = 0
Next, you have to factorize and solve it :
x² - 4 = 0
x² + 2x - 2x - 4 = 0
x(x + 2) - 2(x + 2) = 0
(x + 2)(x - 2) = 0
x + 2 = 0
x = -2
x - 2 = 0
x = 2

Answers
Complete question :
At a certain school, 25% of the students wear a watch and 30% wear a bracelet. 60% of the students wear neither a watch nor a bracelet.
a) One of the students is chosen at random. What is the probability that this student is wearing a watch or a bracelet?
b) What is the probability that this student is wearing both a watch and a bracelet?
Answer:
0.40 ; 0.15
Step-by-step explanation:
Let :
w = watch
b = bracelet
P(W) = 0.25
P(B) = 0.3
P(either a watch or a bracelet) = P(WuB)
P(neither a watch nor a bracelet) = 1 - P(WuB)
1 - P(WuB) = 0.6
a.) probability that student is wearing a watch or a bracelet = P(WuB)
P(neither a watch nor a bracelet) = 1 - P(WuB)
0.6 = 1 - P(WnB)
P(WnB) = 1 - 0.6
P(WnB) = 0.4
B.) probability that student is wearing both a watch and a bracelet : P(WnB)
Using the probability relation :
P(WuB) = P(W) + P(B) - P(WnB)
0.4 = 0.25 + 0.30 - P(WnB)
0.4 = 0.55 - P(WnB)
P(WnB) = 0.55 - 0.40
P(WnB) = 0.15

Answers
Hey there!
The answer to your question is D.) After coupons, the game is $2.25 cheaper at Techno Hut
First, we will solve for the price of Techno Hut's game. Let's find the amount of the discount:
0.10 x 40
4
Then, we take the discount off the price:
40 - 4 = 36
The price of the game at Techno Hut is $36
Next, we find the price of the game at Gamer World. Let's find the amount of the discount:
0.15 x 45
6.75
Then, we take the discount off the price:
45 - 6.75 = 38.25
The price of the game at Gamer World is 38.25
Therefore, Techno Hut is cheaper.
Hope it helps! Good luck and have a great day!
