Answer:
slope of AB=2
AB(distance)=4√5
Step-by-step explanation:
slope of AB=6-(-2)/-4-(-8)
=2
AB=√(-8-(-4))^(2+(-2-6)^(2
=4√5 or 8.94427
next time pls type clearly ur question, because actually I don't know what kind of answer that u want to know. sorry
For a 95% confidence interval, the corresponding z-score is 1.96. Therefore the deviation will by 1.96*0.5 lbs = 0.98 lbs. Therefore, the confidence interval will be (5 - 0.98, 5 + 0.98), which is (4.02, 5.98). The weight range is from 4.02 lbs to 5.98 lbs.
Answer:
the numbers who's difference is 16 and the product is 720 is
36 &20
Explanation:
to finding numbers you have to express the equation in a quadratic equation then Factor it.
since the two numbers have a difference of 16 you can say that the first number is x and the second number is x -16 then their product is 720.
x(x-16)=720
x²-16x=720
x²-16x-720=0
(x-36)(x+20)
there are two possible value of x but since you are looking for the positive value of x, choose the positive value of x the first number is 20.
To find the second number
x-16=20
x=20+16
x=36
the second number is 36
<u>Now </u><u>to </u><u>check</u>
<u>3</u><u>6</u><u>-</u><u>2</u><u>0</u><u>=</u><u>1</u><u>6</u>
<u>2</u><u>0</u><u>*</u><u>3</u><u>6</u><u>=</u><u>7</u><u>2</u><u>0</u>
Make an equation.
Also, convert 3 weeks into days ⇒ 3 · 7 = 21 days.
x + 2x + 4x = 21
x is Jared.
2x is Max (because half of 4 is 2).
4x is Wesley.
Now solve the equation.
7x = 21
x = 3
Jared = x
Max = 2x
Wesley = 4x
Jared = 3 days
Max = 2(3) = 6 days
Wesley = 4(3) = 12 days
