Answer:
y = 5/2x + 4Step-by-step explanation:
Midpoint of JK:
x = (-12 + 8)/2 = -4/2 = -2y = (3 - 5)/2 = -2/2 = -1Slope of the line JK:
m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5Perpendicular lines have negative reciprocal slopes.
So the line r has a slope 5/2 and passes through the point (-2, -1)
Equation of r:
y = 5/2x + b-1 = 5/2(-2) + b-1 = -5 + bb = 5 - 1b = 4So the equation is:
y = 5/2x + 4jordan can jog 1/3 of a mile in 1/6 of an hour.what is his speed in miles per hour
Answer:
The answer is 2 miles per hour
Step-by-step explanation:
Given
distance = 1/3 miles
time taken = 1/6 hour
Required,
The speed with which Jorgan Jogs
Step two:
We know that the formula for the situation is
Speed= distance/time
Speed= 1/3/1/6
Speed= 1/3*6/1
multiply the numerator by the inverse of the denominator
Speed=6/3
Speed= 2 miles per hour

If the probability is 0.65 that a marriage will end in divorce within 20 years, what is the probability that out of 7 couples just married in the next 20 years
(A) None will be divorced?
(B) All will be divorced?
(C) Exactly 6 will be divorced?
(D) At least 6 will be divorced?
Answer:
0.00064
0.049
0.185
0.234
Step-by-step explanation:
Using binomial distribution formula :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
p = 0.65
1 - p = 1 - 0.65 = 0.35
n = 7
(A) None will be divorced?
P(x = 0) : 7C0 * 0.65^0 * 0.35^7
= 1 * 1 * 0.00064339296875
= 0.00064
(B) All will be divorced?
P(x = 7) : 7C7 * 0.65^7 * 0.35^0
1 * 0.04902227890625 * 1
= 0.049
(C) Exactly 6 will be divorced?
P(x = 6) : 7C6 * 0.65^6 * 0.35^1
7 * 0.075418890625 * 0.35
= 0.18477628203125
= 0.185
(D) At least 6 will be divorced?
P(x ≥ 6) = p(6) + p(7)
P(6) = 0.185
P(7) = 0.049
P(x ≥ 6) = 0.185 + 0.049 = 0.234
A plane takes off from an airport on the bearing S 29°W. It continues for 20 minutes then changes to bearing S 52°W and flies for 2 hours 20 minutes on this course then lands at a second airport. If the plane's speed is 420 mph, how far from the first airport is the second airport? Round to the nearest mile.
A. 1011 mi
B. 1111 mi
C. 1010 mi
D. 1110 mi
Answer: 1110 miles
Step-by-step explanation:
Given that :
Speed (V) = 420 mph
t1 = 20 minutes = 20/60 = 0.3333 hour
t2 = 2 hours 20 minutes = 2.333 hours
Distance = speed * time
d1 = 420 * 0.333 = 140 miles
d2 = 420 * 2.33333 = 979.98 = 980 miles
Using cosine rule :
x = sqrt(d1² + d2² - 2(d1 * d2) cos 157
x = sqrt(140^2 + 980^2 - 2(140 * 980) cos157
x = sqrt(1232586.5)
x = 1110.2191
x = 1110 miles

I- I would help but- o meh lord
please help me with this math!
Answer:
Please check the explanation.
Step-by-step explanation:
Given the polynomial function
[tex]f\left(x\right)\:=x^3+2x^2-16x-32[/tex]
Let us determine the factors by solving
[tex]\:\left0\right\:=x^3+2x^2-16x-32\:[/tex]
[tex]\left(x+2\right)\left(x+4\right)\left(x-4\right)=0[/tex]
Using the zero factor principle:
if [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
[tex]x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0[/tex]
Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.
Therefore,
YES
(x+2)(x+4)(x-4)And (x-2) (x+6) are not the factors of the polynomial function.
Therefore,
YES

You have a coupon for 20% off the shoes. Will the cost of the shoes be: MORE THAN $65.95 or LESS THAN $65.95 EXPLAIN
Answer:
take $65.95 times (0.0825) for the sales tax = 5.44
then, add the tax of $5.44 to the original amount of $65.95 = $75.39
Step-by-step explanation:
Answer: less than $65.95
Step-by-step explanation: because its taking 20% away from $65.95
$65.95 - 20% = $52.76

0-4-9 = -13 or -4-9 = -13
Explanation:
Basically it starts at 0, then it moves to the left of the number line meaning it subtracts. It moves to the left by 4, so it is subtracting 4 from 0. Then it moves to the left again by 9, so you subtract 9 from 0-4
In the end, it is 0-4-9 or you can remove the 0 and be -4-9

Which statement about Jackson’s claim is true?Jackson is correct because he used the length of each decimal to compare the different costs. For example, 0.149 < 0.1457 < 0.05625.Jackson is correct because he compared values in equal place values to compare only the decimals with the same length. For example, 0.0561 < 0.0564 < 0.05625.Jackson is incorrect because he should compare the values in equal place values to compare all the decimals, not just those of the same length. For example, 0.0561 < 0.05625 < 0.0564.Jackson is incorrect because the case of 24 oz bottles is less per ounce than the 59 oz bottle and the 89 oz bottle. For example, 0.1457 < 0.0561 < 0.0564.

If the fraction 414/x-10 is equivalent to -23 , find the value of x. Show your work. Use reasoning to find x.
Answer:
x = -8
Step-by-step explanation:
Solve for x by getting rid of the fraction.
414/(x-10) = -23
414 = -23(x-10)
414 = -23x + 230
184 = -23x
-8 = x
The starting salaries of individuals with an undergraduate degree from UC Riverside are normally distributed with a mean of $40,000 and a standard deviation of $5,000. What is the probability that a randomly selected individual with an undergraduate degree from UC Riverside will have a starting salary of $34,000 to $46,000?
Answer:
The probability that a randomly selected individual with an undergraduate degree from UC Riverside will have a starting salary of $34,000 to $46,000 is 0.7699.
Step-by-step explanation:
Let X denote the starting salaries of individuals with an undergraduate degree from UC Riverside.
It is provided that, [tex]X\sim N(\$40,000,\ \$5,000^{2})[/tex]
Compute the value of P (34000 < X < 46000) as follows:
[tex]P (34000 < X < 46000)=P(\frac{34000-40000}{5000}<\frac{X-\mu}{\sigma}<\frac{46000-40000}{5000})\\\\=P(-1.2<Z<1.2)\\\\=P(Z<1.2)-P(Z<-1.2)\\\\=0.88493-0.11507\\\\=0.76986\\\\\approx 0.7699[/tex]
Thus, the probability that a randomly selected individual with an undergraduate degree from UC Riverside will have a starting salary of $34,000 to $46,000 is 0.7699.

It took a car 4 days to travel 3036 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answer:
31.625 rounded up is 32mph
Step-by-step explanation:
if you take how many days it took to travel then there are 24 hours in a day so you would do 24 times 4 which gives you 96.
then you take 3036 and divide that by 96 and you get your answer.
