Answer:
Step-by-step explanation:
#6
a n
---- = ---- Solve for a. Note that if we multiply both sides of this equation by
m p n
m, we get a = m * ----
p
m*n
and this simplifies to a = mn/p or a = ---------
#7 Solve mx = np for x. We want to isolate x on the left side. Dividing
both sides by m isolates x on the left and adds the divisor m on the right:
np
mx = np => x = ------
m
#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:
-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c
Answer:
B. The two lines are neither parallel nor perpendicular.
Step-by-step explanation:
First, put both lines into the same format. In this example, we're going to use y=mx+b format.
x - 4y = -9
-4y = -x + -9
y = (-x + -9) / -4
y = (x+9)/-4
y = (-1/4)x + (-9/4)
y = 3x - 7
If two lines are parallel, they have the same slope. (ie 4 and 4)
If two lines are perpendicular, one line's slope is the negative reciprocal of the other. (ie 4 and -1/4)
Neither is true here.
Answer: The mean of the data is 433.75, variance of the data is 99667.19 and the standard deviation of the data is 315.7011.
Explanation:
The given data is 900, 35, 500 and 300.
The number of observation is 4.
Formula of mean is,
The formula of variance is given below,
The variance of the data is 99667.19
The standard deviation of the data is 315.7011.
The other information or values of given chart is shown in the attached table.
8 sandwiches cut into 4 pieces each gives you 32 pieces.
32 pieces divided into 2 plates equals 16 on each plate.
8×4 = 32
32/2=16
Answer:
45 is the answer
Step-by-step explanation:
first you have to know the sum of interior angle of that pentagon (540)
then add the all angle.
148 + x + 112 + 90 + 3x + 10 = 540.
or, 360 + 4x = 540
or, 4x = 540 - 360
or, 4x = 180
or, x = 180/4
or, x = 45
hope it will help you☺✌
