Can someone help me find this arc, please.

alexira [117]

Answer:

Arc AC = 90°

Step-by-step explanation:

Postulate:

The measure of an arc will ALWAYS be equal to the measure of the central angle of the circle.

The angle of arc AC is marked with a square.

That square mark means it is 90°.

So the arc would also measure 90°.

A used car dealer has 30 cars and 10 of them are lemons (i.e.~ mechanically faulty used cars), and you don't know which is which

Triss [41]

Answer: Hence, the probability that he will get at least one lemon is 0.70.

Step-by-step explanation:

Since we have given that

Number of cars = 30

Number of lemon cars = 10

Number of other than lemon cars = 30-10 = 20

According to question, he bought 3 cars,

we need to find the probability that you will get at least one lemon.

So, P(X≤1)=1-P(X=0)=1-P(no lemon)

Here, P(no lemon ) is given by

$\dfrac{20}{30}\times \dfrac{20}{30}\times \dfrac{20}{30}=(\dfrac{20}{30})^3$

so, it becomes,

$P(X\geq 1)=1-(\dfrac{20}{30})^3=1-(0.67)^3=0.70$

Hence, the probability that he will get at least one lemon is 0.70.

Please help me with this question!!

Bess [88]

Answer:

$x=16 * cos(46)$

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

$cos (46^{o} ) = \frac{x}{16}$ (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

$x=16 * cos(46)$

Hope this helps!

Andrew walks 3/4 mile in 10 minutes. Jill walked 4/5 mile in 15 minutes. What was the difference in their speeds, in miles per h

andreyandreev [35.5K]

The difference of their speeds is 1.3 mph because Andrew was walking 4.5 mph and Jill was walking 3.2mph.
