Goals scored by a hockey team in successive matches are 5,7,4,2,4,0,5,5 and 3. What is the number of goals, the team must score

Stels [109]

Answer:

Step-by-step explanation:

Total goals /total no. of matches = 4

5+7+4+2+4+0+5+5+3+x / 10 = 4

35 + x = 4 × 10

x = 40 - 35

x = 5

So, the team must score 5 inorder to get the average of 4 goals per match.

I don't understand how to solve this can you me solve this please? n-10= 5/6n - 7 - 1/3n

expeople1 [14]

Answer:

n = 6

Step-by-step explanation:

n - 10= 5/6n - 7 - 1/3n

n - 10 = 15/18n - 7 - 6/18n

n - 10 = 9/18n - 7

18/18n - 10 = 9/18n - 7

9/18n = 3

1/2n = 3

n = 6

In Exercise,find the horizontal asymptote of the graph of the function.<br> f(x) = 7/1+5x

S_A_V [24]

You compare the degrees of the numerator and the denominator.

The numerator has a degree of 0 and the denominator has a degree of 1.

Since the numerator < denominator the degree is 0.

The average 30- to 39-year old man is 69.5 inches tall, with a standard deviation of 2.7 inches, while the average 30- to 39-yea

andre [41]

Answer:

b) LeBron is relatively taller because he has a larger z-score.

Step-by-step explanation:

Z-score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

LeBron James:

Height of 81 inches, while the average 30- to 39-year old man is 69.5 inches tall, with a standard deviation of 2.7 inches, which means that we have to find Z when $X = 81, \mu = 69.5, \sigma = 2.7$

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{81 - 69.5}{2.7}$

$Z = 4.26$

Candace Parker:

Height of 76 inches, while the average 30- to 39-year old woman is 64.2 inches tall, with a standard deviation of 3.2 inches. This means that we have to find Z when $X = 76, \mu = 64.2, \sigma = 3.2$

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{76 - 64.2}{3.2}$

$Z = 3.69$

Who is relatively taller?

Due to the higher z-score, LeBron James, and thus, the correct answer is given by option b.
