Answer:
0.1994 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 166 pounds
Standard Deviation, σ = 5.3 pounds
Sample size, n = 20
We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(sample of 20 boxers is more than 167 pounds)
Calculation the value from standard normal z table, we have,
0.1994 is the probability that the mean weight of a random sample of 20 boxers is more than 167 pounds
H+6.9=1.4
H=1.4-6.9 -6.9 FOR BOTH SIDE
H=-5.5
Answer:
the answer is option A
Step-by-step explanation:
The measure of ∠4, ∠3 and ∠7 are 115°, 65° and 65° respectively.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
∠2 + ∠4 = 180° (sum of angles in a straight line)
∠4 + 65 = 180
∠4 = 115°
b) ∠2 = ∠3 (vertically opposite angles)
∠3 = 65°
c) ∠3 = ∠7 (corresponding angles)
∠7 = 65°
The measure of ∠4, ∠3 and ∠7 are 115°, 65° and 65° respectively.

Answer:
14.) y = 5/3x - 3
15.) y = -x + 3
16.) y = 2/5x + 1
17.) y = 3x
18.) y = -1/2x + 4
Step-by-step explanation:
Slope-intercept form:
y = mx + b
Where m is the slope and b is the y-intercept
Then, substitute with the given slope and y-intercept!
