Answer:- $\frac{3\pi}{10},60^{\circ},\frac{\pi}{2},\frac{2\pi}{3},255^{\circ}$

Explanation:-

Substitute $\pi=180^{\circ}$ , we get

1. Correct.

$\frac{3\pi}{10},60^{\circ},\frac{\pi}{2},\frac{2\pi}{3},255^{\circ}$

=54°,60°,90°,120°,255°

2. Not correct.

255° is not less than 60.°

3. Not correct.

$\frac{\pi}{2}$ =90° which is not less than 60°.

4. Not correct

255° is not less than 60°.

I rent a gym for $150.00 for 30 students. Another time I rent the gym for $270.00 for 70 students. I need to find a fixed rate.

masha68 [24]

Answer: y = 3x + 60

Step-by-step explanation:

Set up two equations and solve the system:

270 = 70x + b

- (150 = 30x + b)

120 = 40x

3 = x

Input "x" into one of the equations and solve for "b":

150 = 30x + b

150 = 30(3) + b

150 = 90 + b

60 = b

Equation: y = 3x + 60

This means that there is a flat fee of $60 plus a rate of $3 per student

A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue, and the rest are orange.Let B = t

pentagon [3]

Answer:

$P(R\ and\ B) = 0.0256$

Step-by-step explanation:

Given

$Red = 22$

$Yellow = 38$

$Green = 20$

$Purple = 28$

$Blue = 26$

$Orange = 16$

Required

Determine the probability of red then blue jelly? i.e. P(R and B)

From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean

So, we have:

$P(R\ and\ B) = P(R)\ and\ P(B)$

This is then solved further as:

$P(R\ and\ B) = P(R)\ *\ P(B)$

$P(R\ and\ B) = \frac{n(R)}{Total}\ *\frac{n(B)}{Total - 1}$

The probability has a denominator of Total - 1 because the number of jelly beans reduced by 1 after the picking of the red jelly bean

The equation becomes:

$P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{150- 1}$

$P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{149}$

$P(R\ and\ B) = \frac{22*26}{150*149}$

$P(R\ and\ B) = \frac{572}{22350}$

$P(R\ and\ B) = 0.02559284116$

$P(R\ and\ B) = 0.0256$
