X= 51 is the answer you need to remember that since they share a straight line you add the together to get 180 which is half a circle
Answer:
91+c
Step-by-step explanation:
The equation to find the perimeter of the triagle is every side added together. We know 2 sides which means we add them to get 91. Then we know we don't know the next number but we add it so we just put the c where the next number to be added would go.
Answer:
the number of grams of zinc contain is 78
Step-by-step explanation:
The computation of the number of grams of zinc contain is shown below:
Given that the ratio of zinc to copper is 3:16
And, the jar of the chemical has 416 grams copper
So, the number of zinc grams would be
here we assume the zinc grams be x
Now the equation would be
3 ÷ 16 = x ÷ 416
Now applied the cross multiplication
16x = 416 × 3
x = (416 × 3) ÷ 16
= 78
Therefore the number of grams of zinc contain is 78
Answer:
The procedure does results in a binomial distribution.
Step-by-step explanation:
For a binomial probability distribution to be applicable, certain conditions have to be met which are :
There must be a fixed number of observations ; here the number of observations are : 79
All observations must be independent ; the observations are independent ; odd or even
Observations must fall into one of two categories : success category or failure. Here, observations can be odd or even
The probability of success must be equally likely for each observation.
Hence, the procedure results in a binomial probability distribution.
Step-by-step explanation:
slope of the segment through (-9, -8) and (-5, 6) is (-9-(-5))/(-8-6)=-(-4)/(-14)=2/7
this means the slope of the perpendicular is -7/2.
the midpoint of the segment is (-7, -1)
so the line is y+1=(-7/2)(x+7).
