Answer:

Mauricio's score for each event is 7.

Step-by-step explanation:

Mauricio scored a total of 34.42 points in five gymnastic events.

We can round off his score as 35.

To find Mauricio's score for each event, divide total score and no of events as follows :

$n=\dfrac{35}{5}\\\\=7$

Hence, Mauricio's score for each event is 7.

Answer:

$- 4 {x}^{2} - 11x + 13$

Step-by-step explanation:

$( - {x}^{2} + 9) + ( - 3 {x}^{2} - 11x + 4)$

$- {x}^{2} + 9 - 3 {x}^{2} - 11x + 4$

$- 4 {x}^{2} - 11x + 13$

Add an intersection the red light times normally distributed by the mean of three minutes and a standard deviation of .25 minute

Soloha48 [4]

95% of red lights last between 2.5 and 3.5 minutes.

<u>Step-by-step explanation:</u>

In this case,

The mean M is 3 and
The standard deviation SD is given as 0.25

Assume the bell shaped graph of normal distribution,

The center of the graph is mean which is 3 minutes.

We move one space to the right side of mean ⇒ M + SD

⇒ 3+0.25 = 3.25 minutes.

Again we move one more space to the right of mean ⇒ M + 2SD

⇒ 3 + (0.25×2) = 3.5 minutes.

Similarly,

Move one space to the left side of mean ⇒ M - SD

⇒ 3-0.25 = 2.75 minutes.

Again we move one more space to the left of mean ⇒ M - 2SD

⇒ 3 - (0.25×2) =2.5 minutes.

The questions asks to approximately what percent of red lights last between 2.5 and 3.5 minutes.

Notice 2.5 and 3.5 fall within 2 standard deviations, and that 95% of the data is within 2 standard deviations. (Refer to bell-shaped graph)

Therefore, the percent of red lights that last between 2.5 and 3.5 minutes is 95%

1. Solve the system of equations by graphing:

rjkz [21]

Answer:

Step-by-step explanation:

y = -3x - 3

m = -3_______

b = -3________

y = 2x + 2

m = 2_______

b = _2_______

SOLVE NOW : -3x - 3 = 2x + 2

- 5x = 5

x = -1

subst in y : y = 2(-1)+2 = 0

the solution is : ( - 1 , 0 )

y = -3x- 3 an equation for the line 'red'

y = 2x+2 an equation for the line 'bleus'
