So they’re supplementary angles which means that they add up to 180°… The equation would be: 5w+1+7w-7=180
5w+1+7w-7=180 (combine like terms)
12w-6=180
+6 +6
12w=186
w=15.5
Im not sure what they’re asking for but if they’re asking for w, your answer is 15.5, if they’re asking for the angle measure on the left, your answer is 78.5° & if they’re asking for the angle measure on the right, your answer is 101.5° :) hope this helps
Here are 3= 7:1 28:4 56:8
Answer:
47 13/21
Step-by-step explanation:
Given
11 1/9 x 4 2/7
First change the fractions to improper fractions.
We have ,
100/9 x 30/7
Multiply through
3000/63
Divide the numerator and denominator by 3
1000/21
47 13/21
Answer:
True
Step-by-step explanation:
Point estimation of a population parameter provides an estimate of a single value calculated from the sample that is likely to be close to its value to the unknown parameter. Itis to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.
For example, in estimation, we may estimate the mean and the variance of a population by computing the mean and the variance of the sample drawn from a population.
