Based on data from a car bumper sticker study, when a car is randomly selected, the number of bumper stickers and the corresponding probabilities are as shown below. complete parts (a) through (d)

Yes

The mean is equal to 0.6. The standard deviation is equal to 1.5

The maximum usual value is 3.5.

max: μ + 2σ = 0.578 + 2(1.462161414) = 3.502322828

The minimum usual value is 0.

min: μ – 2σ = 0.578 – 2(1.462161414) = -2.346322828

No, because the probability of having more than one bumper sticker is equal to 0.120 that is greater that 0.05

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
