Answer:
x=62
Step-by-step explanation:
The sum of x ,28, and 90 is 180 since it forms a straight line
x+28+90 = 180
Combine like terms
x+118 =180
Subtract 118 from each side
x+118-118 =180-118
x= 62
Answer:
1.20
Step-by-step explanation:
Let mean be represented by M and standard deviation by d. The score will be x and sample number of games be n
To get the test statistic, t for Fernanda's test, we use the formula

Substituting 156 for mean, M then 150 for score x and 30 for standard deviation while 36 for n then

t=1.20 when put in two decimal place
15y -8y + 12 = -3
7y = - 15
y = -15/7
or
y = 2.1
Answer:
(10, -9)
Step-by-step explanation:
Xs = 5 -(0-5) = 5+5 = 10
Ys = -2 -(5-(-2)) = -2 - 7 = -9
so, the coordinates of point S => (10, -9)
Answer:
It is the second one.
Step-by-step explanation:
a and e are equal because they are mirrored. d and b are equal because they are on the same line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.
