Select the correct answer from each drop-down menu. What types of insurance should Selina purchase given her situation? Selina wants to cover the loss of potential damages to her house in case of a natural calamity, such as a tornado. So, she should purchase a ___ insurance policy. She is also quite concerned about her dog’s health. To be on the safe side, she should also buy a ___ insurance policy.
1.
a. Homeowners
b. Disability
c. Automobile
2.
a. Pet
b. Life
c. Health
Answer:
1. Homeowners insurance policy
2. Pet insurance policy
Step-by-step explanation:
Homeowners' insurance policy is an insurance policy that covers the damages made to an insured place of residence. The insurance company takes care of damages that occur inside, and outside the house. Damaged furnishing as well as accidents that occur within the house are also catered to by the insurance company. The policyholder pays a deductible out of the total amount of money for the claims of damages while the insurance company takes care of the additional cost. So Selina would resort to a homeowners' insurance policy for her house so as to cover the loss in case of a natural calamity.
The Pet insurance policy also takes care of the veterinary costs of pets just in case they fall ill or suffer any other accidents. Selina would buy a pet insurance policy to take care of this potential problem.
Answer:
Selina wants to cover the loss of potential damages to her house in case of a natural calamity, such as a tornado. So, she should purchase a 1. homeowners insurance policy. She is also quite concerned about her dog’s health. To be on the safe side, she should also buy a 2. pet insurance policy.What is the y-coordinate of point D after a translation of
(x, y) - (x + 6,7 - 4)?
Hey There!!
Your answer will be 1.
Step-by-step explanation:
If the coordinates of the point D' are (x, y), then, after translation, it will be
D(x + 6, y - 4).
that is 6 units right and 4 units down
It is given that the point before translation is D'(3, 5).
So, x + 6 = 3 + 6 = 9 and
y - 4 = 5 - 4 = 1
So, the y coordinate of point D after translation is 1.

Priscilla has three cups of apples left. She wants to use them in another fruit salad.
How would she find out how much of the other fruits she needs to use up the
remaining apples?
Answer:
To use up the remaining 3cups of apples, she would need 3cups of oranges, 12cups of strawberries, 6cups of cherry and 9 cups of grape.
Step-by-step explanation:
This is a continuation of the question on the recipe for making salad. The initial recipe from her grandmother is stated below (found on brainly, ID 6786167).
The fruit salad recipe calls for one part apple, one part orange, four parts strawberry, two parts cherry, and three parts grape.
Priscilla uses the same measuring cup to measure all of the fruit, so one part is equal to one cup of diced fruit.
Number of cups required for each fruit in the original recipe:
apple = 1 cup , orange = 1 cup, strawberry = 4cups, cherry = 2cups, grape = 3cups
Original ratios of the cup of fruit respectively = 1:1:4:2:3
Total number of cups required in the original recipe: 1+1+4+2+3 = 11 cups
Now for this question, 3 cups of apples are remaining. And we want to find number of other fruits she needs in order to use up the remaining apples.
To do this we would use the ratios of the cup of fruit.
When we had 1 apple, the ratio was = 1
Now we have 3apples, the new ratio = 3×original ratio
=3×1 = 3
This means we would multiply each of the fruit ratios by 3
For orange, new ratio = 3×1 = 3
For strawberries, new ratio = 3×4 = 12
For cherry, new ratio = 3×2 = 6
For grape, new ratio = 3×3 = 9
To use up the remaining 3cups of apples, she would need 3cups of oranges, 12cups of strawberries, 6cups of cherry and 9 cups of grape.
Answer:
Priscilla uses one part orange, four parts strawberry, two parts cherry, and three parts grape for every one part apple. So, to use three times the quantity of apples, she will have to use three times the quantity of the other fruits as well. She needs three parts orange, twelve parts strawberry, six parts cherry, and nine parts grape for three parts apple.

Instructions: Find the measurement of the angle indicated in the following parallelogram.
Orion is working with a data set that compares the outside temperature, in degrees Celsius, to the number of gallons of ice cream sold per day at a local grocery store.
The data has a line of best fit modeled by the function f(x) = 3x + 4 . Orion determines that when the temperature is 25∘C, the store should sell about 79 gallons of ice cream. The correlation coefficient of the data is 0.39.
Explain how accurate Orion expects the prediction to be.
Answer: kindly check Explanation.
Step-by-step explanation:
The function f(x) = 3x + 4 is a linear regression model. Orion's prediction was obtained by Substituting 25 for x to obtain the predicted variable
f(25) = 3(25) + 4 = 75 + 4 = 79.
However, with a correlation Coefficient of 0.39, which is a numerical value of range - 1 to +1 and is used to measure the statistical relationship between the dependent variable (number of gallons of ice-cream sold per day) and the independent variable (temperature).
The closer the correlation Coefficient (r) value is to +1 or - 1, the stronger the degree of correlation. Positive r values depicts positive relationship while negative r values depicts negative relationship. The closer the r value is to 0. The weaker the relationship and a r value of means there is no Relationship exists between the two variables.
With a correlation Coefficient of 0.39, we can Infer that that only a moderate positive relationship exists between temperature and gallons of ice cream sold per day.

help i need to submits this quickly
============================================================
Explanation:
Pick two points on this diagonal line where (x,y) has whole number coordinates. Two such points that fit the description are (-3,2) and (1,-1)
Use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-1-2)/(1-(-3))
m = (-1-2)/(1+3)
m = -3/4 is the slope
-------------------------
Extra info:
It doesn't matter which two points you pick as you'll always get the same slope value. Of course, the points must be on the diagonal line.
The negative slope indicates the line goes downhill as you move from left to right.
slope = rise/run = -3/4
rise = -3, a negative rise means we go down 3 units
run = 4, we go to the right 4 units
so we go down 3 and over to the right 4. This will move us from (-3,2) to (1,-1)

You are remodeling your kitchen. You've contacted two tiling companies who
gladly told you how long it took their workers to tile a floor of a similar size.
Jim completed half the floor in 12 hours. Pete completed the other half of the
floor in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what
equation would you use to find the rate that Jim can lay tiles? Let x represent
Jim's rate.
Answer:
12x=10(25+x)
Step-by-step explanation:
Jim's rate=x
Pete's rate=y
Jim and Pete lays the same number of tiles.
So we have,
12x=10y
Pete's can lay 25 more tiles than Jim per hour
We have
y=25+x
Substitute y=25+x into 12x=10y
12x=10y
12x=10(25+x)
12x=250+10x
12x-10x=250
2x=250
x=250/2
=125
x=125
12x=10(25+x) is the equation used to find the rate that Jim can lay tiles

The roots of the function y = 4x² + 2x - 30 are -3, 5/2 after using the zero product property.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
y = 4x² + 2x - 30
To find the roots of the quadratic equation plug y = 0
4x² + 2x - 30 = 0
4x² + 12x - 10x - 30 = 0
4x(x + 3) - 10(x + 3) = 0
(x + 3)(4x -10) = 0
x + 3 = 0 or 4x - 10 = 0
x = -3 or x = 10/4 = 5/2
Thus, the roots of the function y = 4x² + 2x - 30 are -3, 5/2 after using the zero product property.

Question 20

Three security cameras were mounted at the corners of a triangular parking lot. Camera 1
was 260 ft from Camera 2, which was 210 ft from Camera 3. Cameras 1 and 3 were 234 ft
apart. Which camera had to cover the greatest angle?
Answer:
The camera had to cover the greatest angle is CAMERA 3 because it had the largest angle of 71.47°
Step-by-step explanation:
From the above question,
We have:
Camera 1 = Angle A
Camera 2= Angle B
Camera 3 = Angle C
A = 210ft
B = 234ft
C = 260ft
We need to find Angle A( angle of camera 1) using the cosine rule
A=(B² + C² - 2BCCosA)
210² = 234² + 260² - 2 × 234 × 260 × CosA
210² = 122356 - 121680CosA
Square both sides
210² = 122356 - 121680CosA
44100 = 122356 - 121680CosA
121680CosA = 122356 - 44100
121680CosA = 78256
Cos A = 78256/121680
Cos A = 0.6431295201
A = arc cos (0.6431295201)
A = 49.974422249°
Angle A approximately = 49.97°
Using the Sine rule to find the Angle B
A/Sine A = B/Sine B
210ft/Sine 49.97° = 234ft/Sine B
210ft × Sine B = 49.97° × 234ft
Sine B =( Sine 49.97° × 234ft)/210ft
B = arc sin (0.8532172354)
Angle B = 58.56334
Approximately = 58.56°
Angle C = 180 - (49.97 + 58.56)°
Angle C = 71.47°
Therefore, the camera had to cover the greatest angle is Camera 3 because it had the largest angle of 71.47°
Answer:
Camera. 3

one row three column
==========================================================
Explanation:
We have a 1x3 matrix multiplied with a 3x3 matrix. This is a valid operation since the number of columns in the first matrix matches with the number of rows in the second matrix.
The resulting answer matrix will be 1x3 as it takes the number of rows of matrix A and the number of columns from matrix B, helping forming the answer matrix C.
The answer matrix looks like
[tex]C = \begin{bmatrix}x & y & z\end{bmatrix}[/tex]
where x, y and z are placeholders for actual numbers.
To get the value of x, we apply the dot product of the left matrix with the first column of the right matrix
x = (-1)(3)+(2)(2)+4(0) = -3+4+0 = 1
We'll do a similar set of steps to find y
Apply the dot product on the second column this time
y = (-1)(6)+2(4)+4(6) = -6+8+24 = 26
and the third column as well
z = (-1)(1)+2(0)+4(2) = -1+0+8 = 7
Since x = 1, y = 26 and z = 7, we can say
[tex]C = \begin{bmatrix}x & y & z\end{bmatrix}[/tex]
becomes
[tex]C = \begin{bmatrix}1 & 26 & 7\end{bmatrix}[/tex]
How many ways are possible to choose 3 days out of February? NOTE: Use 28 days for the number of days in February. A) 3276 B) 378 C) 20475 D) 2925
Answer:
A) 3,276 ways.
Step-by-step explanation:
In this case, choosing February 1, February 12, and February 20 would be the same thing as choosing February 12, February 1, and February 20. So, since order does not matter, we will use a combination to solve the question.
The formula for combinations is...
n! / [r!(n - r)!], where n = the number of days in February (28) and r = the number of days you are choosing (3).
28! / [3! * (28 - 3)!]
= 28! / (6 * 25!)
= (28 * 27 * 26) / 6
= (14 * 9 * 26) / 1
= 14 * 9 * 26
= 126 * 26
= A) 3,276.
