What numbers go in the boxes?

Answer:

the answer is around 1.87 cents

Answer:

$7

Step-by-step explanation:

25x4=100

156-100=56

56/4=14

14 spent on earrings each earring was $7

If Four friends each brought matching necklaces and two pairs of earrings. The necklaces were priced at $25.00.If the total bill for all 4 friends was $156.00. Then 28 is the price of one pair of earrings

Two or more expressions with an Equal sign is called as Equation.

Based on the conditions formulate

Four friends each brought matching necklaces

Cost of each necklace is 25

25x4=100

So for four necklaces it is 100.

Now with remaining amount they purchased two pairs of ear rings

156-100=56

With 56 they purchased earrings

56/2=28

Cost of one pair of ear rings is 28.

Hence price of one pair of ear ring is 28

Answer:

#4= 1

#5= A=9,216

B=360

Step-by-step explanation:

number five x equals 9 and y = 1,024 so it's asking us that if x = 81 what would y = and to get 81 you need to multiply 9 by 9 so all you have to do is multiply 1024 by 9 to get 9,216 so y = 9,216 and the same thing goes for B

Answer:

10 hours

Step-by-step explanation:

For about 10 hours.

6 times 10 = 60

60+16= 76

Answer:

D. 49

Step-by-step explanation:

To complete the square, you have to take half of the value next to x, 14 in this case, and square that.

1/2 of  14 is 7

7 squared is 49

so, the final equation is x²+14x+49

Given: The Table of Values

To Find: The least-squares regression line for the data set in the table by using the desmos graphing calculator.

SolutionThe general form of least-squares regression line is: y = mx + b Where, m is the slope and b is the y-intercept.

Where, m is the slope and b is the y-intercept.By using the desmos graphing calculator, we get

m 2.55 b -6.435 Substitute these Values

y = (2.55)x + (-6.435)

y = 2.55x - 6.435

Answer: A

The expression to generate the parameters and statistics is y tilde m x plus b, the correct option is C.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that;

x subscript 2 baseline y subscript 2 baseline;

1 2

2 9

3 7

4 12

Now,

To find the least-squares regression line for a data set using Desmos, you need to follow these steps:

Enter the data as a table in Desmos. For example, type {1, 2, 3, 4} in the x column and {2, 9, 7, 12} in the y column.

Type y tilde m x plus b in the expression box. This tells Desmos to find the values of m and b that minimize the sum of squared errors between y and y tilde (the predicted values).

Click on the wrench icon next to the expression to see the parameters and statistics. You should see something like this:

m = 2.8 b = -1.6 r² = 0.84

This means that the equation of the least-squares regression line is:

y tilde = 2.8 x - 1.6

And that the coefficient of determination (r²) is 0.84.

Therefore, by expression the answer will be y tilde m x plus b.

x:0.3=5:6-->x/0.3=5/6-->6×x=0.3×5-->6x=1.5-->x=1.5/6-->x=0.25Answer..

Answer:

x = -3, y = 24

Step-by-step explanation:

y=−7x+3;y=−8x

Step: Solve y=−7x+3 for y:

y=−7x+3

Step: Substitute−7x+3 for y in y=−8x:

y=−8x

−7x+3=−8x

−7x+3+8x=−8x+8x(Add 8x to both sides)

x+3=0

x+3+−3=0+−3(Add -3 to both sides)

x=−3

Step: Substitute−3 for x in y=−7x+3:

y=−7x+3

y=(−7)(−3)+3

y=24(Simplify both sides of the equation)

Answer: variable is distributed normally, then approximately two-thirds of the population will within plus or minus one standard deviation of the mean

Step-by-step explanation:

The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.
