I think it should be 50, really sorry if it wasn't multiplying.

I would guess 50. Simple multiplication.

What does it mean to evaluate an expression in 5th grade

MrRa [10]

Answer:

Usually it means to solve it. Sometimes they give you values to substitute in for variables (letters) in the math sentence/equation/expression.

Does that make sense?

At a particular garage, 60% of the customers require an oil change, 20% require tire rotation, and 75% of customers require at l

ZanzabumX [31]

Answer:

a. 5%

b. 55%

c. 70%

Step-by-step explanation:

a. The probability of customer wanting both services (P(O&T)) is:

$P(O)+P(T)+P(O\&T) = 0.75\\P(O)+P(O\&T) =0.60\\P(T)+P(O\&T) = 0.20\\P(O)+P(T)+P(O\&T) -[P(O)+P(T)+2P(O\&T)]=0.75 -(0.60-0.20)\\P(O\&T)=0.05=5\%$

The probability is 5%

b. The probability that the customer will need an oil change, but not a tire rotation (P(O)) is :

$P(O)+P(O\&T) = 0.60\\P(O\&T) = 0.05\\P(O) =0.60-0.05 = 0.55 = 55\%$

The probability is 55%

c. The probability that the customer will want exactly one of these two services (P(O)+P(T)) is:

$P(O)+P(T)+P(O\&T) = 0.75\\P(O\&T) = 0.05\\P(O)+P(T) =0.75-0.05 = 0.70 = 70\%$

The probability is 70%

Help me find answer to this

Debora [2.8K]

Answer:

$\angle B=41.81^\circ$

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

$\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}$

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

$\displaystyle \sin \angle B=\frac{2}{3}=0.667$

Calculating the inverse sine function:

$\angle B=\arcsin (0.667)$

$\boxed{\angle B=41.81^\circ}$

What is the equation of a line that passes through (1,5) and (3,11)? Show work please.

jekas [21]

First, find the gradient/slope:
Use slope formula:
m=(y2-y1)/(x2-x1)
=(11-5)/(3-1)
=6/2
=3
Then use the line equation formula:
y=mx+c
You can substitute (1,5) if you like, also must substitute the slope as well!
5=3x1+c
c=2
Then find the full equation, which gives you the answer:
y=3x+2
