Answer:

C. x = 6

Step-by-step explanation:

2*6 + 4 = 16

Answer: c six less than twice is the same as two times a number minus six

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

"Twice a number" means a variable/mystery number times 2; aka 2x.

"Six less than" means minus/subtract six.

So, therefore it's 2x - 6.

Answer: just multiply the same sides that same number and that add the answers all together

given:20%

solution,

=20/100

=2/10

=1/5

First get the average passing yards:

(3,832 + 3,779 + 3,655 + 3,642 + 3,579) / 5 = 3,697.4

Now get the squared residuals for each quarterback's passing yards. That is, compute the difference between each data and the average, then square the result. For example,

(3,832 - 3,697.4)^2 = 134.6^2 = 18,117.2

For the others, you should get squared residuals of

6,658.56

1,797.76

3,069.16

14,018.6

Take the sum of the squared residuals, then - since this is a sample, and not a population of all quarterbacks - divide the sum by 5 - 1 = 4 to get the variance:

(18,117.2 + 6,658.56 + 1,797.76 + 3,069.16 + 14,018.6)/4 = 10,915.3

The standard deviation is just the square root of the variance:

√(10,915.3) ≈ 104.48

the answer is 3697.4

Answer:

7.039

Step-by-step explanation:

7 + 3/100 + 9/1000

7 + 0.03 + 0.009

7.039

Answer:

7.039

Step-by-step explanation:

7 = 7

3/100 = .03

9/1000 = .009

therefore

7 + 3/100 + 9/1000 = 7 + .03 + .009

Answer:

1 km = 100000 cm

Solution :

Mean time for an automobile to run a 5000 mile check and service = 1.4 hours

Standard deviation = 0.7 hours

Maximum average service time = 1.6 hours for one automobile

The z - score for 1.6 hours = [tex]$\frac{1.6-1.4}{0.7 / \sqrt{50}}$[/tex]

                                           = 2.02

Now checking a normal curve table the percentage of z score over 2.02 is 0.0217

Therefore the overtime that will have to be worked on only 0.217 or 2.017% of all days.

Answer:

B. x = 0.14

Step-by-step explanation:

Inx = -2

x = e^(-2)

x = 0.135

x = 0.14 (to two d.p)

The solution of the equation ln x =-2 is 0.14

The correct option is (D)

Logarithms are the inverse of exponents.

Given that:

ln x =-2

Shifting the log on the right side, it will become exponential

x = [tex]e^{-2}[/tex]

x = 0.135

x = 0.14 (two decimal places)

Answer:

238 times

Step-by-step explanation:

Given

[tex]a = 175[/tex] -- first week

[tex]r = 16.5\%[/tex]--- growth per week

[tex]t = 2[/tex] --- time

Required

The number of times it was downloaded in 2 weeks

An exponential growth is represented as:

[tex]y = a(1 + r)^t[/tex]

So, we have:

[tex]y = 175 * (1 + 16.5\%)^2[/tex]

[tex]y = 175 * (1.165)^2[/tex]

[tex]y = 175 * 1.357225[/tex]

[tex]y = 237.514375[/tex]

[tex]y = 238[/tex] -- approximated

Answer:

AB = 16

Step-by-step explanation:

The radius of the circle = 10

From the center of the circle to B = 10 (radius)

Since a right angle is formed at point E, we can apply Pythagorean theorem to find EB.

Thus:

EB² = 10² - 6²

EB² = 100 - 36

EB² = 64

EB = √64

EB = 8

EB = AE = 8

therefore,

AB = AE + EB = 8 + 8

AB = 16

Answer:ab=16

Step-by-step explanation:

5/8 * 1/5 = 1/8 or .125

Answer:

B

Step-by-step explanation:

You can read this as "find g of f of 2"

Also written as g(f(2)).

What we're doing is is looking at the function f and getting the value when you input 2. f(2)

Since the function f is the curved one, you will find the coordinate where the input is 2. At input 2 or x=2, we get the value of 0.

Now back to g(f(2)) -- Because we have found the value of f when it is 2, we can replace this equation with:

g(0)

Now we find the value we get from g when we put 0 as the input. When 0 is our input, or when our x is 0, we see the point of g is (0,2) so our output is 2.

Answer:

$168

Step-by-step explanation:

Divide $56 by $2

$56 ÷ $2 = 28

Thus $2 was donated 28 times

He donated $2 every time $6 was spent, then

money spent = 28 × $6 = $168

Answer:

$168

Step-by-step explanation:

We have the following ratio

Spent at shop : donated to charity

6:2

we know that

x:56

To solve this we just mulitply 6 by 28 (28 because this is what we mulitplied the two in our original ratio to reach 56)

6*28=168
