Pavlova-9 [17]1 year ago
4 0

Answer:

x = 7

Step-by-step explanation:

<u>Distribute </u>-

12x − 66 + 15 = 3x + 12

<u>Combine Numbers and Variables</u> -

12x - 51 = 3x +12

<u>Get x on one side (isolate x)</u> -

9x - 51 = 12

9x = 63

<u>Divide 9</u> -

x =7

SOLUTION

TO DETERMINE

The degree of the polynomial

CONCEPT TO BE IMPLEMENTED

POLYNOMIAL

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

DEGREE OF A POLYNOMIAL

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.

EVALUATION

Here the given polynomial is

In the above polynomial variable is z

The highest power of its variable ( z ) that appears with nonzero coefficient is 5

Hence the degree of the polynomial is 5

FINAL ANSWER

The degree of the polynomial is 5

Times for an ambulance to respond to a medical emergency in a certain town are normally distributed with a mean of 450 seconds a
Gnoma [55]

Answer:

(D)109

Step-by-step explanation:

Mean = 450 seconds

Standard deviation = 50

First, we determine the probability that the expected response time is between 400 seconds and 500 seconds, P(400<x<500)

Using the Z-Score,

P(\frac{x-\mu}{\sigma}

From the Z-Score table

P(-1<x<1) = 0.68269  

The probability that the expected response time is between 400 seconds and 500 seconds is 0.68269.

Since there are 160 Emergencies

Number whose expected time is between 400 seconds and 500 seconds

=160 X 0.68269 \approx 109

Isolate x; you must get all the constants on one side of the equation and the variables on the other side. Use subtraction/addition to do this. Reply to me once you've done that if you still need help.

iren2701 [21]

Answer:

It would take them 6 minutes to paint the wall and 12 to paint the other half : 18 minutes

Step-by-step explanation:

Say that the student who can paint a wall in 12 minutes is painting half of the wall it would take them 6 minutes

As the other student who can paint the same wall in 24 minutes also paints half of a wall it would take that person 12 minutes.
