which of these is an example of a discrete random variable 1) hours worked at job, weight of a child, number of siblings, length of a fish

Answer:

hours worked at job, number of siblings are examples of discrete random variable.

Step-by-step explanation:

Discrete random variable has values that can be counted. It has finite data that does not change continuously.

Hours worked at a job can be counted at the end of the day.

The weight of a child keeps changing continuously therefore it is not a discrete random variable.

Number of siblings can be counted.

The length of a fish can keep changing day by day therefore it is not a discrete random variable.

A 30°–60°–90° triangle has a shorter leg with a length of 3 units. What is the length of the hypotenuse of the triangle?

The hypotenuse is 6. 30-60-90 triangles have a ration of x, x, and 2x, respectively. So since you have the value for the 30º side, then you just double it to get the hypotenuse's value.

Find the 11th partial sum of the summation of negative 7i plus 22, from i equals 1 to infinity. -220

400

550

-700

The answer is -220

What you do is take -7 and multiply that by (1+2+3+4+5+6+7+8+9+10+11) and then after that add 11 again and multiply it by 22. It would look like this.

-7 x (1+2+3+4+5+6+7+8+9+10+11) +11 x 22

Simplify that to -7 x 66 +11 x 22

now multiply -7 and 66 to get -462

-462 +11 x 22

multiply 11 and 22

-462 + 242

and your final answer will be -220

Dining sets are on sale for 25% off the original price (d), which can be expressed with the function p(d) = 0.75d. Local taxes are an additional 14% of the discounted price, which can be expressed with the function c(p) = 1.14p. Using this information, which of the following represents the final price of a dining set with the discount and taxes applied? c(p) ⋅ p(d) = 0.855pd

c(p) + p(d) = 1.89d

c[p(d)] = 0.855d

d[c(p)] = 1.89p

We will solve the problem step by step to find the final equation that models the problem.

We have:

Step 1:

Dining sets are on sale for 25% off the original price (d)

p (d) = 0.75d

Step 2:

Local taxes are an additional 14% of the discounted price

c (p) = 1.14p

We observe that it is a problem of composition of functions:

the composite function of p with c is

(c (o) p) (d) = c [p (d)] = c (0.75d) = 1.14 (0.75d) = 0.855 d

answer

c [p (d)] = 0.855d

We have:

Step 1:

Dining sets are on sale for 25% off the original price (d)

p (d) = 0.75d

Step 2:

Local taxes are an additional 14% of the discounted price

c (p) = 1.14p

We observe that it is a problem of composition of functions:

the composite function of p with c is

(c (o) p) (d) = c [p (d)] = c (0.75d) = 1.14 (0.75d) = 0.855 d

answer

c [p (d)] = 0.855d

Which measurement is the best estimate for the length of a clothespin? 9 mm 9 cm 9 m 9 km?

The answer would 9 cm. All of the given choices are wrong since the measurement maybe too big or too small. Like for 9 millimeter, it would be too small for a clothespin. While 9km is too big for a clothespin, there is no such thing as a 9km clothespin. While 9 m is also too big. The approximate size of a clothespin is 3 inches, when we convert it to cm, it will be 7 cm. So 9 cm is a best approximate.
