Answer: the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Step-by-step explanation:
Given data;
lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min
hence, height = 1 / ( 52.0 - 50.0) = 1 / 2
now the probability that the class length is between 50.8 and 51 min = ?
P( 50.8 < X < 51 ) = base × height
= ( 51 - 50.8) × 1/2
= 0.2 × 0.5
= 0.1 ≈ 10%
therefore the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%

PLEASE HELP!! WHAT IS x???
9514 1404 393
Answer:
x = 90 degrees
Step-by-step explanation:
There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.
arc DE = 2×∠DFE = 60°
arc EF = 2×∠ECF = 60°
arc CF = 2×∠CEF = 60°
Then arc DEC is ...
arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°
Angle DBC is half the measure of this arc, so is ...
∠DBC = 180°/2 = 90° = x

y=5x+25
Step-by-step explanation:
Since the y intercept for the scatterplot is 25, that means that the only equation that matches the graph is y=5x+25
y=5(0)+25
y=0+25
y=25
Identify the slope and y-intercept for the linear equation below.
y = 1/3x+7
Answer:
Slope is 1/3.
Y-intercept is 7.
Step-by-step explanation:
y = mx + b is the slope-intercept form.
m = slope
b = y-intercept
In the equation, y = 1/3x + 7
m = 1/3
b = 7
Therefore, slope is 1/3 and y-intercept is 7.
Hope this helped! <3
Answer:
Slope is 1/3 and the y- intercept is 7
Step-by-step explanation:
Since the equation is y = mx+b, we know that 1/3 is the slope since m represents the slope and b represent the y-intercept, meaning 7 is the answer.

Part B 1/2-5/8-7/9=7/9-5/8-1/2
Answer:
False
Step-by-step explanation:
1/2 - 5/8 - 7/9 = 7/9 - 5/8 - 1/2
Add 5/8 to both sides.
1/2 - 7/9 = 7/9 - 1/2
Factor -1 out of the right side.
1/2 - 7/9 = -1(-7/9 + 1/2)
1/2 - 7/9 = -1(1/2 - 7/9)
1/2 - 7/9 and 7/9 - 1/2 are opposites. Opposites are not equal unless they are both zero.

The person lost 13 lbs of weight.
What is weight?
Weight is the measure of how heavy an object is. Weight is measured in standard customary units. The mass of an object is the amount of material it contains.
Given that, the person weight=130 lbs and he lost 1/10 of his weight.
We need to find how much weight was lost.
Now, weight lost [tex]=\frac{1}{10} \times 130=13[/tex] lbs.

the area of rectangular plot of land fenced all round is 2000 sq. yards and the total length of fencing 180 yards. find the length and width of plot
9514 1404 393
Answer:
length: 50 ydwidth: 40 ydStep-by-step explanation:
The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...
x(90 -x) = 2000 . . . . where x is length or width
x^2 -90x +2000 = 0 . . . . rearrange to standard form
(x -40)(x -50) = 0 . . . . . . . factor
x = 40 or x = 50
The dimensions of the rectangular plot are 40 yards by 50 yards.
