Given f(x) = 2x – 6, find f( – 4).
Answer:
f(-4) = -14
Step-by-step explanation:
f(x) = 2x – 6
Let x = -4
f(-4) = 2*-4 -6
f(-4) = -8-6
f(-4) = -14
Answer:
The answer is -14
Step-by-step explanation:
f(-4) = 2(-4) - 6
= -8 - 6
= -14

A bag contains 5 blue, 4 red, 7 black and 2 white marbles. What is the probability of selecting a marble that is NOT white?
5+4+7+2=18
18-2=16
16/18
88% chance of selecting a marble that isnt white
Answer:
8/9
Step-by-step explanation:
P(white) = (2) ÷ (5+4+7+2) = (2)/(18) = 1/9
P(not white) = 1 - P(white) = 1 - 1/9 = 8/9

You saved $200 on your new laptop because you bought it online. If this was a 20% savings from the original price, find the original cost of the lapto
Answer:
$1000
Step-by-step explanation:
$200 was saved on a new laptop
This was 20% of the original price of the laptop
Therefote the original cost of the laptop can be calculated as follows
= 20/100x = 200
= 0.2x= 200
Divide both sides by the coefficient of x which is 0.2
x= 200/0.2
= 1000
Hence the original cost of the laptop is $1000

Answer:
Answer is 120/1
Step-by-step explanation:
Marsha can type 120 words per minute. Which ratio describes this relationship between her words typed and time?
Marsha an type in 1 minute = 120 words
The ratio can be described word types and time = 120 words per 1 min
= 120/1
Answer: D
Step-by-step explanation:
My answers correct becuase, A ratio is just the numbers put together put a : in between them. So if it is asking us words to the time all we have to do is put 120 and then a semicolone and 1. 120:1 And D is the one that has that answer so D is correct. Additonal Information: Also sometimes you would have to divide the number equally to get the ratio.

Find a degree measure of each angle in the triangle!
Answer:
B=19
C=42
D=119
Step-by-step explanation:
First, fine the value of x, than use that in each angle to find the measurement.
All angles together in the triangle equal 180
Set your formula up as
180=(x+2)+(3x-9)+7x
180=x+3x+7x+2-9
180-2+9=11x
187=11x
187/11=x
17=x
Angle B
B=x+2
B=17+2
B=19
Angle C
C=3x-9
C=3*17-9
C=42
Angle D
D=7x
D=7*17
D=119
Now add all 3 tougher to check your work
19+42+119 = 180
How many outcome sequences are possible when a die is rolled 4 times where we say for instance that the outcome is 3 4 3 1 if the first roll landed on 3 the second on 4 the third on 3 and the fourth on 1
Answer:
the possible outcome sequences when a die is rolled 4 times is 1296
Step-by-step explanation:
Given the data in the question;
a die is rolled 4 times
and outcomes are { 3, 4, 3, 1 }
we know that; possible number of outcomes on a die is n = 6{ 1,2,3,4,5,6 }
Now when we roll a die lets say, r times
then the total number of possible outcomes will be;
N = [tex]n^r[/tex]
given that; r = 4
Hence if we roll a die 4 times;
Total number of possible outcome N = 6⁴
N = 1296
Therefore, the possible outcome sequences when a die is rolled 4 times is 1296

A coffee vending machine fills 100 cups of coffee before it has to be refilled. On a Monday, the mean number of ounces filled in a cup of coffee was 7.5. The machine is known to have a standard deviation in filling volume of 0.25 ounces. Find a 99% confidence interval for the mean number of ounces dispensed by this machine.
Answer:
The 99% confidence interval for the mean number of ounces dispensed by this machine is (7.44, 7.56).
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.575\frac{0.25}{\sqrt{100}} = 0.06[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 7.5 - 0.06 = 7.44 ounces.
The upper end of the interval is the sample mean added to M. So it is 7.5 + 0.06 = 7.56 ounces.
The 99% confidence interval for the mean number of ounces dispensed by this machine is (7.44, 7.56).
