For each function, find f(-1), f(1), and f(3)<br> f(x)=3x-4

Anna [14]

Answer:

f(x)= 3x-4

f(-1)= 3*-1-4

f(-1)= 2-4

f(-1)= -2

f(x)= 3x-4

f(3)= 3*3-4

f(3)= 9-4

f(3)=5

f(x)= 3x-4

f(1)= 3*1-4

f(1)= 3-4

f(1)= -1

The number of nails of a given length is normally distributed with a mean length of 5 in and a standard deviation of 0.03 find t

umka2103 [35]

Answer:

19 nails

Step-by-step explanation:

Let's first determine the z-score by using the formula:

$z=\frac{x-\mu}{\sigma}$

Where x=5.03, μ=5, σ=0.03 and so:

$z=\frac{5.03-5}{0.03}=1$

We can now use a z-score table to determine that 1.00 is synonymous with 0.8413 meaning 84.13%. This means that 84.13% of the nails are less than or equal to 5.03 inches long. Therefore, since we know 100% = 1 in decimals we can determine that the length greater than 5.03 inches is 1-0.8413=0.1587. This means that 15.87% of the 120 nails are greater than 5.03 inches long.

Finally, we can determine how many nails are greater than 5.03 by determining what is 15.87% of 120 which is:

$120 \times 0.1587 \approx 19$

And so 19 out of the 120 nails are greater than 5.03 inches long.

22=2(w+7)-4w<br> What is w?

SOVA2 [1]

Solve for w by simplifying both sides of the equation, then isolating the variable.

w=−4

Let's solve your equation step-by-step.

22=2(w+7)−4w

Step 1: Simplify both sides of the equation.

22=2(w+7)−4w

22=(2)(w)+(2)(7)+−4w (Distribute)

22=2w+14+−4w

22=(2w+−4w)+(14) (Combine Like Terms)

22=−2w+14

22=−2w+14

Step 2: Flip the equation.

−2w+14=22

Step 3: Subtract 14 from both sides.

−2w+14−14=22−14

−2w=8

Step 4: Divide both sides by -2.

−2w /−2 = 8 /−2

Answer:

w=−4

A 100-gram sample of a radioactive isotope decays at a rate of 6% every week. How much of the sample will be left one year from

Dvinal [7]

4 grams sample will be left after 1 year

Step-by-step explanation:

The decay function for percentage decay is given by:

$y =a (1-r)^x$

Here,

a is the initial value

r is the rate

x is the number of time periods

Given

Initial value = 100 grams

Rate = 6% = 0.06

Time = 1 year = 52 weeks

Putting the values in the formula

$y = 100 (1-0.06)^{52}\\y = 100(0.94)^{52}\\y = 4.00\ grams$

Hence,

4 grams sample will be left after 1 year
