IrinaVladis [17]
Out of your $67 for the day, $40 of it goes to the rental before you even drive it out of the lot.  That leaves you $27 a day for mileage.

$27 / $0.18 per mile = <u>150 miles</u> per day, tops.

It is known that 60% of customers will need additional maintenance on their vehicle when coming in for an oil change. A random s
inn [45]

Answer:

the probability that more than 70% of customers in the sample will need additional maintenance is 0.0371

Step-by-step explanation:

From the information given:

we are to determine the probability that more than 70% of customers in the sample will need additional maintenance

In order to achieve that, let X be the random variable that follows a binomial distribution.

Then X \sim Bin(48, 0.6)

However 70% of 48 samples is

= 0.7 × 48 = 33.6 \simeq 34

Therefore, the required probability is:

= P(X> 34)

= \sum \limits ^{48}_{x=34} (^{48}_{x}) (0.6)^x(1 - 0.6)^{48-x}

= \dfrac{48!}{34!(48-34)!} (0.6)^{34} (0.4)^{48-34}

= 4.823206232 \times 10^{11} (0.60)^{34}(0.4)^{14}

= 0.03709524328

\simeq 0.0371

A right triangle has side lengths AC = 7 inches, BC = 24
Nady [450]

Therefore, the measures of the angles in triangle ABC is as follows:

  • m∠A 73.7°, m∠B = 16.3°, m∠C = 90°

<h3>How to find angles of right triangle?</h3>

The measure of the angles in the right triangle can be found as follows:

Using trigonometric ratios,

sin ∅ = opposite / hypotenuse

sin ∅ = 7 / 25

∅ = sin ⁻¹ 0.28

∅ = 16.2602047083

∅ = 16.3°

Hence,

m∠B = 16.3°

m∠C = 90°

m∠A = 180 - 90 - 16.3 = 73.7°
