Answer:

strange phrasing of a question

If one assumes that the "observation" was from 3:00 pm - 5:00 pm (2 hours)

and the ball was ONLY "bounced" 10 times (3+7)

we can can say that the rate was 10 bounces/2 hours or 5 b.p.h. (bounces per hour)

Papessa [141]

Answer: 60 hours.

Step-by-step explanation:

Let be "x" the amount of hours Nick practice in March and "y" the amount of hours Nick plans to practice in April.

Set up a system of equations:

$\left \{ {{x=42} \atop {y=x+18}} \right.$

Applying the Substitution Method, we can substitute the first equation into the second equation in order to find the value of "y". Therefore you get this result:

$y=x+18\\\\y=(42)+18\\\\y=60$

39 percent of all customers who enter a store will make a purchase. Suppose that 6 customers enter the store and that these cust

aleksklad [387]

Answer:the probability that exactly five customers make a purchase is 0.033

Step-by-step explanation:

The formula for binomial distribution is expressed as

P(x = r) = nCr × q^(n - r) × p^r

Where

p = probability of success

q= probability of failure

n = number of sample

From the information given,

39 percent of all customers who enter a store will make a purchase. It means that the probability of success, p = 39/100 = 0.39

The probability of failure q, would be 1 - p = 1 - 0.39 = 0.61

n = 6

The probability that exactly five customers make a purchase is expressed as

P(x = 5) = 6C5 × 0.61^(6 - 5) × 0.39^5

P(x = 5) = 6 × 0.61× 0.39^5 = 0.033

In triangle ABC, angle bisectors line AD, line BE, and line CF meet at I. If DI = 3, BD = 4, and BI = 5, then compute the area o

Nikitich [7]

The area of triangle ABC is the amount of space on the triangle

The area of the triangle is 54.84 square units

<h3>How to determine the area of triangle ABC</h3>

Start by drawing the triangle (see attachment)

Next, calculate the measure of angle B using the following tangent ratio

$\tan(B/2) = \frac 34$

This gives

$\tan(B/2) = 0.75$

Take the arc tan of both sides

$B/2 = 36.87$

Multiply by 2

$B = 73.74$

Next, calculate the length of side AD using the following equation

$AD = \tan(B) * BD$

This gives

$AD = \tan(73.74) * 4$

$AD =13.71$

The area of the triangle is then calculated as:

$Area = AD * BD$

This gives

$Area = 13.71 * 4$

$Area = 54.84$

Hence, the area of the triangle is 54.84 square units
