You add 3+3+5=11 parts
132 divided by 11 =12
12 X 3 = 36kg
12 X 3 = 36kg
12 X 5 = 60kg
To make sure add them up to see if it totals to 132 so 36 + 36 + 60 = 132
Answer:
m∠T = 68°
m∠U = 95°
m∠V = 112°
m∠W = 85°
Step-by-step explanation:
m<V = (14z - 7)°
m<W = 10z°
m<T = 8z°
Recall that the sum of the opposite angles of a cyclic quadrilateral equals 180°.
Therefore:
(14z - 7)° + 8z° = 180°
Find z
14z - 7 + 8z = 180
22z - 7 = 180
22z = 180 + 7
22z = 187
22z/22 = 187/22
z = 8.5
Answer:
6
Step-by-step explanation:
|-10+4| = |-6|= 6
inside the | | the equation is done normally. that's why it has a negative at first. then, once getting rid of the bars, you change the number to a positive
Answer:
2.51 < σ < 3.92
Step-by-step explanation:
We will use Chi-Square distribution to create the interval. We have the following information:
n = 41
Level of Confidence : 95%,
This corresponds to Chi-Square values of:
24.433 for the left tail and 59.342 for the right tail
We need to calculate the sample Variance. This is done on attached photo 1 (the shortcut formula for finding variance was used)
We get s = 9.3866.
See the construction of the confidence interval on the second attached photo
