Answer:
472 in²
Step-by-step explanation:
This net is made up of 3 identical rectangles and 2 identical triangles.
Area of a rectangle = width x length
Area of a triangle = 1/2 x base x height
<u>Rectangle</u>
- width = 8 in
- length = 19 in
<u>Triangle</u>
<u>Surface Area</u>
SA = 3(8 x 19) + 2(0.5 x 8 x 2)
⇒ SA = 456 + 16
⇒ SA = 472 in²
Answer:
a. Discrete
b. Discrete
c. Not a random variable
d. Continuous
e. Discrete
f. Continuous
Step-by-step explanation:
The discrete random variable is countable while continuous random variable is measurable.
a. The number of fish caught is a discrete random variable because these are countable.
b. The number of text book authors are also countable so it is a discrete random variable.
c. The political party affiliation of adults is not a random variable because the political party affiliation depends on person's interest and it cannot be randomly assigned to person. Also random variable is the numerical outcome of random experiment whereas political affiliation is the categorical variable that results in non numerical responses such as Democrat, Republicans etc.
d. The square footage of a house is measurable and so it is a continuous random variable.
e. The number of free dash throw attempts are countable so it is a discrete random variable
f. The weight of Upper T dash bone steak is measurable and so it is a continuous random variable.
Answer:
x-intercept: (2,0)
y-intercept: (0,4)
Step-by-step explanation:
x-intercept: when y = 0
y = -2x + 4
0 = -2x + 4
x = 2
y-intercept: when x = 0
y = -2x + 4
y = -2(0) + 4
y = 4
Answer:
Please check the explanation.
Step-by-step explanation:
Given
P(Z > 1.96)
To determine
What probability expression is equivalent to P(Z > 1.96)
Suppose Z is a standard normal variable.
Therefore,
P(Z > 1.96) = 1 - P(Z ≤ 1.96)
solving
= 1 - Ф(1.96)
= 1 - 0.9750
= 0.0250
