Answer:
- B. The probability that the student received a grade better than C is 0.45
Step-by-step explanation:
<u>Total number of students:</u>
- 15 + 30 + 35 + 16 + 4 = 100
<h3>Statements</h3>
A.
- p(<D) = 4/100 = 0.04
- 0.04 ≠ 0.2
- Incorrect
B.
- p(>C) = (30 + 15)/100 = 45/100 = 0.45
- 0.45 = 0.45
- Correct
C.
- p(not A or B) = (100 - 15 - 30)/100 = 55/100 = 0.55
- 0.55 ≠ 0.45
- Incorrect
D.
- p(B or C) = (30 + 35)/100 = 65/100 = 0.65
- 0.65 ≠ 0.35
- Incorrect
Answer:
−7b−9k+6
Step-by-step explanation:
−4b+(−3b)=−7b
+(−9k)=−9k
12−6=6

<u><em>Step-by-step explanation:</em></u>
- Since the triangle is right use the tangent ratio to solve for x

- Multiply both sides by
x ×
( divide both sides by
)
x = ≈ ( nearest tenth )
The best answer I believe is t - 2
Answer:
C) . y=(1/10)x+3
Step-by-step explanation:
Given the equation of the line is y=-10x+8
It is in the form of y=mx+c where m is the slope of the line. Now on comparision we get m1=-10.
We knoew that two lines are perpendicular iff the product of their slopes is equal to -1.

the slope of the recquired line =
=
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept
Given the y intercept of the recquired line (b)=3
The recquired line is
y=mx+b
y=(1/10)x+3
