Step-by-step explanation:
d = √(x2-x1)²+(y2-y1)²
d = √(-3-(-3))²+(-7-(-5))²
d = √ 0+(-2)²

~ N(,)
What is the probability that the average of 35 numbers will be less than 7.9?
Answer:
22.5
Step-by-step explanation:
The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.
(a) Distribution of X is uniform distribution X to U(4,11).
(b) Sample size (n) = 35, distribution of mean would be moderate with value = (4+11)/2 = 7.5
Standard deviation = √ [(11-4)^2/(12*35] = 0.3415
Now
x to N (7.5, 0.3415)
(c) We have to find probability that the average of 35 numbers will be less than 7.9.
P(x < 7.9) = P(x < 7.9; 7.5; 0.3415)
Z = (7.9 -7.5)/0.3415
Z = 1.1713
P(x< 7.9)= P(Z < 1.1713)= 0.87932.
Thus, The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.

Can someone help me find m
Answer:
69 degrees
Step-by-step explanation:
m is a point, if your trying to find lkh, is 69
lkm=111, and jkl=180, so 180-111=jkm
jkm=69
angles that are diagonal from each other are the same degree
lkh=69
hope this helps, if not see me in the commnets
HOPE THIS HELPS, BRAINLIEST PLEASE
Answer:
m < LKH = 69°
Step-by-step explanation:
Given that m < LKM = 111° and that:
<LKM and <LKH are adjacent angles as they share the same vertex, point K, and same ray between them, KL:
Then we can assume that m < LKM and m < LKH are supplementary angles whose sum = 180°.
Therefore, we can establish the following equation:
m < LKM + m < LKH = 180°
111° + m <LKH = 180°
Subtract 111° from both sides to solve for m < LKH:
111° - 111° + m <LKH = 180° - 111°
m < LKH = 69°
Therefore, the measure of < LKH is 69°.

a cylindrical tank with radius 7 m is being filled with water at a rate of 4 m3/min. how fast is the height of the water increasing?
Answer:
0.026 m / min.
Step-by-step explanation:
Volume V = π7^2h
V = 49πh
dV/dh = 49π
Rate that the volume is increasing is 4 m3/min.
So dV/dt = 4
dV/dt = dh/dt * dV/dh
4 = dh/dt * 49π
dh/dt = 4/49π
= 0.026 m / min.
The required height of the water increase is given as 0.026 m/min.
Given that,
A cylindrical tank with a radius of 7 m is being filled with water at a rate of 4 m3/min, how fast is the height of the water increasing is to be determined
Volume is defined as the ratio of the mass of an object to its density.
Here,
The volume of the cylinder =πr²h
Substitute the value in the above formula
Volume V = π7²h
V = 49πh
V/h = 49π - - - - - - - (1)
Rate of the filling the tank is given,
V/t = 4
V = 4t
Substitute this in equation 1
4t / h = 49π
h / t = 0.026 m/s.
Thus, the required height of the water increase is given as 0.026 m/min.

Please explain how you got the answer.
9514 1404 393
Answer:
(x +6)(3x +4)
Step-by-step explanation:
The usual approach to this is to look for factors of the product 3·24 that have a sum of 22.
72 = 1·72 = 2·36 = 3·24 = 4·18 = 6·12 = 8·9
Sums of these factor pairs are 73, 38, 27, 22, 18, 17.
Now, you can rewrite the expression splitting the middle term into two parts:
3x² +4x +18x +24
x(3x +4) +6(3x +4) . . . . . . factor by grouping
(x +6)(3x +4) . . . . . . . . . . your factored form
_____
Additional comment
I find this method easiest to explain and to do without error. There are various "X" methods in which you write the product at the top (3·24) and the sum at the bottom (22), then fill in the sides with the factors having that product and sum (4, 18). When the leading coefficient is not 1, there are methods added to this that get you to the correct factors.
One such method is to use the leading coefficient inside parentheses: (3x+4)(3x+18) Then divide that product by the leading coefficient:
(3x +4)(3x +18)/3 = (3x +4)(x +6).
In some cases, each of the binomials needs to be divided by part of the leading coefficient; not the whole thing, as here.

You borrow $450 from a friend the first week and pay the friend back $10 each week thereafter. Write the first six terms in the sequence Explain what the sixth term means in the context of the situation
Write the first six terms in the sequence. Explain what the sixth term means in the context of the situation.
Using an arithmetic sequence, we have that:
The first six terms of the sequence are: 450, 440, 430, 420, 410 and 400.The 6th term of 400 means that after 6 weeks, the amount you owe your friend is of $400.What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, we have that:
On the first week, you owe the friend $450, hence the first term is [tex]a_1 = 450[/tex].Each week, you pay back $10, hence the amount you owe is reduced by 10, and the common difference is of d = 10.Hence, considering the common difference, each term is the previous term subtracted by 10, and:
The first six terms of the sequence are: 450, 440, 430, 420, 410 and 400.The 6th term of 400 means that after 6 weeks, the amount you owe your friend is of $400.More can be learned about arithmetic sequences at https://brainly.com/question/6561461
