F(-12) if f(x) = 2x + 15

Mathematics
1 answer:
Alenkinab [10]4 years ago
8 0

Answer: f(-12)=-9

Step-by-step explanation:

We have the following function:

f(x)=2x+15

And we have to evaluate it when x=-12, this means we have to substitute x by -12:

f(-12)=2(-12)+15

Solving:

f(-12)=-24+15

Finally:

f(-12)=-9

a cell phone company charges a monthly fee plus a 0.35 for text messages sent they charge 25.00 monthly fee and your bill is 58.
riadik2000 [5.3K]
Hey,

So first we are told that they charg a fixed fee of 25:00 right?That means even if you didn’t send any text messages you still have to pay 25:00.

So first we have to subtract that 25:00 form 58.25 right?This means the rest of the bill is for text messages OK?
So he spent 33.25(this is the answer to the subtraction) on the text messages right?
And for every text he sent he was charged 0.35 right? So we have to divide 33.25 by 0.35 right?
And that gets us 95.

Now we can double check the answer by multiplieng 95 by 0.35 and adding 25.

So th answer is 95

Hope this helps !!

What is the value of X
maw [93]

Answer:

x = 30

Step-by-step explanation:

The two angles add to a right angle which is 90 degrees

30 +2x = 90

Subtract 30 from each side

30 +2x - 30 =90-30

2x= 60

Divide each side by 2

2x/2 = 60/2

x = 30

Find m&lt;1 <br> Please please
enyata [817]

Answer:

it should equal 68 degrees.

Step-by-step explanation:

if you are looking for the value of m<1, you would first need to find the value of the missing angle on the left triangle. the angles in triangles are equal to 180 degrees, so the equation would be 180 = 50 + 80 + x, and x = 50.

Then move to the middle triangle. The angle you solved for has an angle "connected" to it, its vertical pair, which also equals 50. Then you solve for the last angle, the angle on the right. 180 = 50 + 62 + x, and x = 68.

m<1 is equal to its vertical angle, which is the angle you just solved for. its value should be 68 degrees.

if that wasn't what you were looking for, sorry. hope this helped :)

Suppose Z has a standard normal distribution with a mean of 0 and standard deviation of 1. 27% of the possible Z values are grea
inessss [21]

Answer:

27% of the possible Z values are greater than 0.613

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 0, \sigma = 1

27% of the possible Z values are greater than

The 100 - 27 = 73rd percentile, which is X when Z has a pvalue of 0.73. So X when the z-score is 0.613.

Z = \frac{X - \mu}{\sigma}

0.613 = \frac{X - 0}{1}

X = 0.613

27% of the possible Z values are greater than 0.613
