Answer:

Step-by-step explanation:

To solve for d, isolate it on one side of the equation.

|d+4|>10

<u>First, you have to subtract by 4 from both sides.</u>

$\sf{d+4-4 < -10-4}$

<u>Solve.</u>

<u />

<u>Add or subtract the numbers from left to right.</u>

-10-4=-14

$\Longrightarrow: \boxed{\sf{{d < -14}}}$

<u>Subtract by 4 from both sides.</u>

$\sf{d+4-4 > 10-4}$

<u>Solve.</u>

<u />

<u>Subtract the numbers from left to right.</u>

10-4=6

$\Longrightarrow: \boxed{\sf{d > 6}}$

<u>Therefore, the correct answer is "D. d<-14 or d>6".</u>

I hope this helps. Let me know if you have any questions.

The sale bin in a clothing store contains an assortment of t-shirts in different sizes. There are 7 small, 8 medium, and 4 large

umka21 [38]

Answer:

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

Step-by-step explanation:

We have 7 small shirts, 8 medium shirts and 4 large shirts

Total number of shirts = 7 + 8 + 4 = 19 shirts

The probability that at least one of the first four shirts he checks is a large is given by

P(at least 1 large) = 1 - P(no large)

So first we need to find the probability that the none of the first four shirts he checks are large.

For the first check, there are 15 small and medium shirts and total 19 shirts so,

15/19

For the second check, there are 14 small and medium shirts and total 18 shirts left so,

14/18

For the third check, there are 13 small and medium shirts and total 17 shirts left so,

13/17

For the forth check, there are 12 small and medium shirts and total 16 shirts left so,

12/16

the probability of not finding the large shirt is,

P(no large) = 15/19*14/18*13/17*12/16

P(no large) = 0.352

Therefore, the probability of finding at least one large shirt is,

P(at least 1 large) = 1 - P(no large)

P(at least 1 large) = 1 - 0.352

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

A bicycle wheel travels 321 in for each revolution. What is the radius of the wheel

Sliva [168]

Answer:

51.1 ≈ r

Step-by-step explanation:

"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.

C = 2· π· r

What is the radius of the wheel ?

321 = 2· π· r, divide both sides of the equation by 2 π

(321/2·π) = r , use calculator, solve and round the answer

51.1 ≈ r

Is b. 840,000 or am I wrong? Correct gets BRAINLIEST! :)

bazaltina [42]

Answer: y=4,728,779,608,739,020,800

Step-by-step explanation: based on the values you have for m & b it would be...

y=4,200 x $2^{50}$

y=4,200 x 1,125,899,906,842,624

y=4,728,779,608,739,020,800
