cricket20 [7]

Step-by-step explanation:

step 1. please write it f(x) = 3x^2 - 7x -32

step 2. f(-4) = 3(-4)^2 -7(-4) - 32

step 3. f(-4) = 48 + 28 - 32

step 4. f(-4) = 44.

For each problem below put the lettered measures in order for greatest to the least

Len [333]

Angles can be used to estimate the side lengths of a shape.

The letters in order of greatest to least are (a), (b) and (c)

The sum of angles at side (a) is:

$a = 30 + 50$

$a = 80$

The sum of angles at side (c) is:

$c = 50 + 90$

$c = 140$

The sum of angles at side (b) is:

$b = 40 + 90$

$b = 130$

So, we have:

$a = 80$

$b = 130$

$c = 140$

The smaller the base angles, the longer the side.

Hence, the letters in order of greatest to least are (a), (b) and (c)

Use the interactive number line to help complete each exercise. Place points at -1 and -4. Complete the inequality: -1 -4. Place

Sliva [168]

Question might not be complete

Answer and explanation:

The signs -1 and -4 lie on the negative side of the number line, left of zero(positive right of zero).

The opposites for each number would be +1 and +4 which would all be on the right side of zero on the number line

Inequality signs or statements to represent greater and lesser number on the number line using the numbers above as examples would be:

-1<+1

-4<-1

+1>-1

+1<4

-1-4<1+4

Numbers that don't have signs attached to them are automatically positive numbers

Use the Normal model N(98,15) for the IQs of sample participants. What IQ represents the 17th percentile? Use the appropriate

maxonik [38]

Answer:

=NORM.INV(0.17,98,15)

Step-by-step explanation:

Consider X represents the IQs of sample participants.

Then X follows the Normal Distribution with mean 98 and standard deviation 15.

That is,

$X \sim N(98,15)$

The probability value is 17th percentile (that is 0.17)

To find the value of X using Excel, the<em> Inverse Normal Distribution </em>is used.

The Excel function =NORM.INV(0.22,105,17) is used to find the IQs of sample participants.
