a recent study showed that the average high school basketball team score 76 points a game with a standard deviation of 8.4 point

krok68 [10]

Answer: 0.0766

Step-by-step explanation:

Let x be the random team scores.

Given: Mean = 76

Standard deviation = 8.4

We assume that x follows normal distribution.

The probability that a random team scores less than 64 points = P(x<60)

$=P(\frac{x-\mu}{\sigma}$

Hence, the probability that a random team scores less than 64 points =0.0766

Please help me i will give brainlist to the correct answer

Answer:

<ABC = 27

< BAC = 126

Step-by-step explanation:

<C = <B since it is an isosceles triangle. We know this since AC - AB

<C = 27 so <ABC = 27

The sum of the angles of a triangle = 180

A + B+ C = 180

A + 27+27 = 180

A + 54 =180

A = 180-54

A =126

< BAC = 126

Sergeu [11.5K]

$l=2 \pi r$
r=0.25 miles
l=2× $\pi$ ×0.25
=0.5 × 3.14
=1.57

120(minutes)÷2(miles)=60(minutes per mile)
60×1.57=94.2 minutes
