Which description best summarizes the correlation between the calls made and the texts sent
Mm
Answer:
Weak positive
Step-by-step explanation:
From. Visual inspection of the scatter plot, the line of best fit will have a positive slope has values of x tends to increase with a corresponding increase in the value of y.
However, the points are scattered across the plotting area meaning that most of the points will be a bit farther away from the regression line. This means a weak correlation between the x and y variables will be obtained. Since the slope is positive, theb the relationship between the variables based on the scatterplot interpretation is a weak positive correlation.

You would burn about 200 calories by walking for 1 hour. About how many calories would you burn if you walk for 15 minutes? PLS HELP ME!!!
Answer:
50
Step-by-step explanation:
So first just sort the times, and the number of calories:
200 calories -> 1hr
x -> 15 mins
So an hour is 4 times the amount of 15 mins, so all you need to do is divide 200 by 4. The answer is 50

What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Solution to this system will give us the solution to the considered equation.
Solution to an equation is finding values of the variable included in the considered equation for which the equation considered evaluates to be true.
The system of equations with the solution (2, 1, 0) is;
2x + y - z = 5

the height. If the rectangle's diagonal measurement is 36
inches, find the height.
Give your answer rounded to 1 decimal place.
inches
Answer:
[tex]length = l\\width = 5 + l\\Diagonal = 36\\diagonal^2 = (5+l)^2 + l^2\\36^2 = 25 + l^2 +10l + l^2\\1296 = 2l^2 +10l +25 \\2l^2 +10l=1271\\\\l_1=\frac{-10+2\sqrt{2567}}{2\cdot \:2},\:l_2=\frac{-10-2\sqrt{2567}}{2\cdot \:2}[/tex]
[tex]l_1=\frac{-5+\sqrt{2567}}{2},\:l_2=\frac{-5-\sqrt{2567}}{2}[/tex]

A group of students were asked how many sisters they have visited in their lifetime. Below is a lot plot of their responses. How many observants are in this data set?
For a given day, temperature can be recorded as hot, mild and cold while weather can be sunny or cloudy. The probability that the temperature is hot, mild and cold are .15, .55 and .30, respectively. Probability that the weather is sunny if the temperature is hot is .67, if the temperature is recorded mild is.36, and if the temperature is cold is.33. Show all the steps including identification of what formulas/properties you used. Points will be deducted from answers if only the final answer is provided.
(a) List all probabilities given in this problem, expressed in terms of events that you define.
(b) What is the probability that it is a sunny day?
(c) Given that the weather is sunny, what is the probability that the temperature is hot? mild? cold?
(d) Given that the weather is cloudy, what is the probability that the temperature is hot? mild? cold?
(e) Is the cloudy weather independent of hot weather?
Answer:
a) p(H) = 0.15
, p(M) = 0.55
, p(C) = 0.30,
p(S | H) i.e. sunny and hot = 0.67
P(c | H) i.e. cloudy and hot = 1 - 0.67 = 0.33
P( S | M) i.e. sunny and mild = 0.36
P(c | M) i.e. cloudy and mild = 1 - 0.36 = 0.64
P( S | C )i.e. sunny and cold = 0.33
P( c | C) = 1 - 0.33 = 0.67
b) ≈ 0.40
c) P ( H | S ) = 0.2513
P( M | S ) = 0.495
P(C | S) = 0.2475
d) P( H I c ) = 0.0825
Probability of mild and cloudy= 0.587
Probability of cold and cloudy = 0.335
e) No
Step-by-step explanation:
a) List All probabilities given in this problem
lets represent each condition with the first letter
Temperature : Hot ( H ) , mild ( M ) , cold ( C )
weather : Sunny ( S ) and cloudy ( c )
hence the probabilities are ;
p(H) = 0.15, p(M) = 0.55, p(C) = 0.30,
p(S | H) i.e. sunny and hot = 0.67
P(c | H) i.e. cloudy and hot = 1 - 0.67 = 0.33
P( S | M) i.e. sunny and mild = 0.36
P(c | M) i.e. cloudy and mild = 1 - 0.36 = 0.64
P( S | C )i.e. sunny and cold = 0.33
P( c | C) i.e. cloudy and cold = 1 - 0.33 = 0.67
b) probability of a sunny day
P ( s ) = P( H ) * P( S | H ) + P( M ) * P( S | M ) + P(C) * P( S | C)
= (0.15 * 0.67) + ( 0.55 * 0.36 ) + ( 0.30 * 0.33 )
= 0.3975 ≈ 0.40
c) Given the weather is sunny ( application of Bayes theorem = P(A and B) / P(B) )
P ( H | S ) = ( 0.15* 0.67 ) / 0.4
= 0.2513
P( M | S ) = 0.55 * 0.36 / 0.3975
= 0.198 / 0.4
= 0.495
P(C | S) = 0.3 * 0.33 / 0.4
= 0.099 = 0.2475
D) Given that the weather is cloudy
P( c ) = 1 - 0.4 = 0.6
P( H I c ) = ( 0.15*0.33) / 0.6
= 0.0825
Probability of mild and cloudy = (0.55*0.64) / 0.6 = 0.587
Probability of cold and cloudy = ( 0.30 * 0.67) / 0.6 = 0.335
e) The cloudy weather ( c ) is not Independent of the hot weather
because condition for independency ( P(c) x P( H ) = P( c and H) ) is not fulfilled.
Which statement best describes the association between variable X and variable Y?
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.
The width of a rectangle measures (4d – 8) centimeters, and its length measures
(7d – 3) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
Answer:
(22d-22) cm
Step-by-step explanation:
perimeter= 2×(4d-8+7d-3)
= 2× (11d-11)
(22d - 22) cm
Answer:
(22d-22)cm
Step-by-step explanation:
Perimeter = 2 x (width + Length)
= 2 x [(4d – 8) + (7d – 3)]
= 2 x (11d-11)
= (22d-22)cm

Answer:
7 · 2 + 14k = 28
Step-by-step explanation:
Why your selected answer was incorrect:
So we are given that j is equal to 2 so lets put it in the equation we're given
7*2 + 14k = 28 This is one of the answers given so this must be the right answer14 + 14k = 28
14 - 14 + 14k = 28 - 14
14k/14 = 14/14
k ≠ 2 k = 1

Problem: How many cubic yards of concrete must be ordered to pour the section
below?
1 ft
18 ft
1.5 ft
Answer:
0.9 yd³
Step-by-step explanation:
Information given:
Length = 18 ft
Width = 1.5 ft
Height = 1 ft
What to find/do:
First, convert the measurement from feet to yards. (3 ft = 1 yard)
Length = 18 ft = 6 yd
Width = 1.5 ft = 0.5 yd
Height = 1 ft = 0.3 yd
Next, find the volume of the shape given. The volume would give us the amount of concrete to use in yards.
Formula for volume = L*W*H
Plug in the values into the formula
V = 6*0.5*0.3 = 0.9 yd³
0.9 cubic yard of concrete must be ordered to pour on the given section.
Area of the volume
