Answer:

d.)

Step-by-step explanation:

2w-4 is the length and the width is 3x that so:

3(2w-4)=6w-12

thats one side so the equation would be

2(2w-4)+2(6w-12)

we have the 2's in front of the parenthesis because theres two sides with length and two sides with width

Answer:

D) $\displaystyle 2(6w - 12) + 2(2w - 4)$

Step-by-step explanation:

$\displaystyle 3[2w - 4] = w → 6w - 12 = w$

Now, according to the Perimeter Formula [for rectangles ONLY], $\displaystyle 2w + 2l = P,$ there are twos factored outside each binomial because in a rectangle, there are two sets of parallel sides, therefore our answer is D).

A company manager for a tire manufacturer is in charge of making sure there is the least amount of defective tires. If the tire

Anestetic [448]

Answer:

0.347% of the total tires will be rejected as underweight.

Step-by-step explanation:

For a standard normal distribution, (with mean 0 and standard deviation 1), the lower and upper quartiles are located at -0.67448 and +0.67448 respectively. Thus the interquartile range (IQR) is 1.34896.

And the manager decides to reject a tire as underweight if it falls more than 1.5 interquartile ranges below the lower quartile of the specified shipment of tires.

1.5 of the Interquartile range = 1.5 × 1.34896 = 2.02344

1.5 of the interquartile range below the lower quartile = (lower quartile) - (1.5 of Interquartile range) = -0.67448 - 2.02344 = -2.69792

The proportion of tires that will fall 1.5 of the interquartile range below the lower quartile = P(x < -2.69792) ≈ P(x < -2.70)

Using data from the normal distribution table

P(x < -2.70) = 0.00347 = 0.347% of the total tires will be rejected as underweight

Hope this Helps!!!

I need help with this math question :(

Ray Of Light [21]

Answer:

k = 5,

y = 5x

Step-by-step explanation:

If y is proportional to x,

y ∝ x

Then the equation will be

y = kx

Her k = proportionality constant.

Now we choose a point from the given table.

Let the point is (2, 10).

By putting the values of x and y in the equation,

10 = 2×k

k = $\frac{10}{2}$

k = 5

This will be true for any point we choose from the table.

And the equation will be y = 5x

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul

VARVARA [1.3K]

Answer:

B. An increase in i, the interest rate, will create an increase in P, the monthly payment.

Step-by-step explanation:

We have the formula for the monthly payment as,

$P=\frac{i \times PV}{1-(1+i)^{-n} }$ ,

where P = monthly payment, i = rate of interest, PV = present value and n = time period.

Now, as i increase we get that (1+i) increases and so $(1+i)^{n}$ increases.

This gives us that, $\frac{1}{(1+i)^{n} }$ decreases and so $1-\frac{1}{(1+i)^{n}}$ decreases

Therefore, $\frac{1}{1-(1+i)^{-n} }$ increases.

So, we get that as i increases , the value of P will increase.

Hence, option B is correct.

romanna [79]

Given that:

f(x) = -2x²-2x+10

f(2) = -2(2)²-2(2)+10

= -2(2*2) - 4 + 10

= -2(4) - 4 + 10

= -8 - 4 + 10

= -12 + 10

= -2 Ans.
