Keiko sold 3 less than three-fourths of his sister's sales. Which expression represents what Keiko sold?
lisov135 [29]

Answer: 3/4x - 3

Step-by-step explanation:

Let his sister's sale be represented by x.

Since we are informed that Keiko sold 3 less than three-fourths of his sister's sales, the expression that represents what Keiko sold will be:

= (3/4 × x) - 3

= 3/4x - 3

The relative frequency for the class with lower class limit 31 is 8.57%.

<h3>How to calculate the frequency?</h3>

It should be noted that the lowrr class frequency is 31 in this case.

Therefore, the relative frequency for the class with lower class limit 31 will be:

= 3/(6+4+4+9+3+9) × 100

= 3/35 × 100

= 8.57%

Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.

An orange is shot up into the air with a catapult. The function given by h(t)+20+60t-16t² models the oranges height in feet, t s
Ganezh [65]

Answer:

  C, E

Step-by-step explanation:

As a rule, these ballistic motion equations are only applicable for heights above the final resting place. Usually, that is the ground (h=0). Time is always measured as a non-negative quantity beginning at the time of launch.

The function is meaningless after the time the object comes to rest on the ground, so the domain of the function extends from 0 until that time.

These considerations allow us to evaluate the offered statements.

  A. The domain never includes negative values. (A is not a true statement)

  B. The heights are the same at times that are symmetrical around the time of the maximum height. Here, that time is about 1.9 seconds, not 1.5 seconds, so the heights will be different at 1 and 2 seconds after launch. (B is not a true statement)

  C. The graph of the function shows the height reaches 0 at about 4.06 seconds, a little after 4 seconds. (C is true)

  D. Based on our answer to C, we know t=10 is outside the domain of the function. (D is not a true statement)

  E. The value of the function is 20 when t=0, so the function tells us the orange is 20 feet above the ground when it is launched. (E is true)

The true statements are C and E.

Beth gets a sum of 5 when she rolls two fair number cubes. What is the probability that one of the fair number cubes is a 1?
ira [324]

Using it's concept, it is found that there is a 0.5 = 50% probability that one of the fair number cubes is a 1.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The outcomes of the pair of cubes that result in a sum of 5 are as follows:

(1,4), (2,3), (3,2), (4,1).

Of those 4 outcomes, 2 involve a number 1, hence the probability is given by:

p = 2/4 = 0.5.
