ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions

EleoNora [17]

Answer:

<h3> X = 2 , X = -3</h3>

Option C is the correct option.

Step-by-step explanation:

$f(x) = a {x}^{2} + bx + c$

Discriminant = ${b}^{2} - 4ac$

Given d = 15

When discriminant D > 0 --> roots are real and distinct. ( unequal )

So , ${3}^{rd}$ option has real and distinct roots.

Hope this helps..

Best regards!!

Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current monthly rent. Let r r

Inessa05 [86]

Answer:

$r = 43.35$

Step-by-step explanation:

Given

$Current\ Rent = r$

$Increment = 15\%$

$New\ Rent = \$51$

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

$\%Increment = \frac{New\ Rent - Current\ Rent}{Current\ Rent}$

Substitute values in the above equation

$15\% = \frac{51 - r}{51}$

Cross Multiply

$51 - r = 15\% * 51$

Convert percentage to decimal

$51 - r = 0.15 * 51$

$51 - r = 7.65$

And the value of $r\ is\ calculated\ using:$

$r = 51 -7.65$

$r = 43.35$

Hence, Cody's current rent is $43.35 monthly

The graph shows the distribution of the number of text messages young adults send per day. The distribution is approximately Nor

erik [133]

The percentage of young adults send between 128 and 158 text messages per day is; 34%

<h3>How to find the percentage from z-score?</h3>

The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.

We are given;

Sample mean; x' = 158

Population mean; μ = 128

standard deviation; σ = 30

We want to find the area under the curve from x = 248 to x = 158.

where x is the number of text messages sent per day.

To find P(158 < x < 248), we will convert the score x = 158 to its corresponding z score as;

z = (x - μ)/σ

z = (158 - 128)/30

z = 30/30

z = 1

This tells us that the score x = 158 is exactly one standard deviation above the mean μ = 128.

From online p-value from z-score calculator, we have;

P-value = 0.34134 = 34%

Approximately 34% of the the population sends between 128 and 158 text messages per day.
