Answer:

The x-intercepts of the continuous function in the table are:

(-4,0) and (4,0).

Step-by-step explanation:

We are given a table of values of the continuous functions as:

(0, 8) (–4, 0) (–4, 0), (4, 0)

The x-intercept of a function is a point on the x-axis i.e. where y=0. (i.e. The x-intercept is where a line crosses the x-axis ).

Here y=f(x).

Hence from the given set of values we have:

f(x)=0 when x= -4 and x=4.

Since we are given the points as (-4,0) and (4,0).

Hence, the x-intercepts of the function f(x) is: (-4,0) and (4,0).

Geometry!! help me!!!

Tems11 [23]

Answer:

1. a=85.8 c=89.2

2. x=29.7 8x=2937. 3

Step-by-step explanation:

2. 8x+x+27°+66°=360°

8x+x=360°-66°-27°

9x=267 >Then divide both sides with 9

x=29,666666...

=8X

=8 (29,66666...)

=237,333...

1. 6X+4X+32°=180°

10X=180°-32

10X=148° >divide both sides with 10

X=14.8

A=6x c=4x+32

=6(14.8) =4(14.8)+32

= 88.8 =91.2

The scores on a psychology exam were normally distributed with a mean of 57

olya-2409 [2.1K]

Answer:

Cutoff for a failing score is 49 and 2.28% students failed.

Step-by-step explanation:

We have been given that scores on a psychology exam were normally distributed with a mean of 57 and a standard deviation of 4.

2 standard deviation below mean would be,

$57-2(4) =57-8= 49$

Therefore,Cutoff far a failing score is 49.

Now let us find out the z-score for our given values,

$z=\frac{x-\mu}{\sigma}$

$z=\frac{49-57}{4}=\frac{-8}{4} =-2$

Now let us look up the probability from normal distribution table.

$P(z$

Therefore, percentage of students failed is 2.28%.
