The total money that will be cost for Mrs. Herrera to purchase candy for her is $10.9889
Given, Number of students that 100% attendance in the class is √196 -1 that is equal to
14-1 = 13.
So, number of students is 13.
Cost of one candy = $0.79+7%(tax)
Cost of one candy = $0.79 + (7% of 0.79)
Cost of one candy = $ 0.79 + 0.0553
Cost of one candy = $0.8453
So , total cost that Mrs. Herrera to purchase candy will be
Total cost = Number of student X Cost of one candy
Total cost = 13 X $0.8453
Total cost = $ 10.9889
Hence, The total cost for Mrs. Herrera to purchase candy for her is $10.9889

An appliance store is having a liquidation where everything in the store is 70% off the regular price. what is the price of a dishwasher that is regularly $519.89? a. $36.39 b. $70.00 c. $155.97 d. $363.92 please select the best answer from the choices provided a b c d
With 70% off the regular price, a dishwasher, regularly priced at $519.89, will be $155.97 only. The answer is C.
Discount is the deduction in the price of a good or service. When this reduced price is expressed in percentage then we call it a discount rate.
If the discount is given in percent, then the amount of discount can be found by using the formula:
Amount of Discount = Regular Price × Rate of Discount
If the regular price of a dishwasher is $519.89, and the discount rate is 70%, using the formula, solve for the discount value.
Amount of Discount = $519.89 x 70%
Amount of Discount = $519.89 × 0.70
Amount of Discount = $363.92
To get the final price of the dishwasher, subtract the discount value from the original or regular price.
price = $519.89 - $363.92
price = $155.97

S
Ox=8
Ox=6
O x = 2
Ox=4
If line PQ bisects line ST at point R and SR=3x+3 and ST=30 then the value of x = 4.
As given in the question,
Line PQ bisects ST at point R
SR=3x+3
ST=30
R is the midpoint of ST as PQ bisects ST this implies
Line SR=1/2 of line (ST)
⇒SR=ST/2
Substitute the value of SR and ST in the given condition
3x+3=30/2
⇒3x+3=15
Subtract 3 from both the sides
⇒3x=12
Divide both the side by 3
⇒3x/3=12/3

Which graph represents the equation y=34x−3?
Answer:
The graph in the top right hand corner.
Hope this helps :)
Step-by-step explanation:
The formula y = mx + b
shows that m is the slope and b is the y-intercept.
m = 34
b = - 3
So to find the equation of the graph I looked at the y-intercept which is -3 and the graph in the right hand corner has a y-inyercept of -3 so that graph represents the equation y = 34x - 3
Reason:
The equation is y = (3/4)x - 3 which is in y = mx+b form
m = slope = 3/4
b = -3 = y intercept
The y intercept of -3 means the point (0,-3) is on the line. Start at this point and go up 3, then to the right 4 to arrive at (4,0) which is the x intercept. The motion "up 3, right 4" is directly from the slope 3/4
slope = rise/run = 3/4
rise = 3 = go up 3
run = 4 = go right 4

given the zeros x = a and x = b then the corresponding factors are
(x - a) and (x - b)
then f(x) is the product of these factors
given zeros x = 6 and x = - 4 then the factors are
(x - 6) and (x - (- 4)) , that is (x - 6 and (x + 4) , then
f(x) = (x - 6)(x + 4)

Answer:
x = 64
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees, so the missing angle in the triangle on the right has an angle measurement of 180 - 47 - 81 = 52 degrees.
Since the angle and the rightmost angle in the triangle on the right are vertical angles. They are congruent.
Finally, since the triangle on the left is an isosceles triangle and the base angles, the angles on the top left and bottom left, are congruent and therefore their angle measures are both x degrees. So, 2x + 52 = 180 and x = 64.
The maximum of a function is the highest point on a graph (identified as an ordered pair). For the function below, what is the x-value of its maximum.
For the graphed parabola we can see that the maximum is at (3, 2), then the x-value is x = 3.
What is the x-value of the maximum?For a function f(x), we define the maximum as a value y = f(x₀), such that:
f(x₀) ≥ f(x) for every value in the domain.
In the case of the graph is really easy to identify the maximum, in this case, it is in the vertex of the parabola.
We can see that the maximum is on the point (3, 2)
Then it is at x = 3, y = 2, from that, we can see that the x-value of the graphed function is x = 3.

Please find me the value of x
Answer:
x = 60°
Step-by-step explanation:
See picture below. When two parallel lines are cut by a transversal there are some special relationships.
Answer:
x = 60°
Step-by-step explanation:
∠ ABO and ∠ CBO are a linear pair and sum to 180° , that is
∠ ABO + ∠ CBO = 180°
150° + ∠ CBO = 180° ( subtract 150° from both sides )
∠ CBO = 30°
∠ XYO and ∠ CBO are alternate angles and are congruent , so
∠ XYO = 30°
∠ XOY and ∠ COY are a linear pair and sum to 180° , then
∠ XOY + ∠ COY = 180°
∠ XOY + 90° = 180° ( subtract 90° from both sides )
∠ XOY = 90°
the sum of the 3 angles in Δ XOY = 180° , that is
x + 90° + 30° = 180°
x + 120° = 180° ( subtract 120° from both sides )
x = 60°

c. the amount of money spent and the number of shirts bought
are have the positive associations.
Positive associations:
Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase.
Given,
Here we have the following relationships,
a. the distance traveled on a trip and the travel time
b. the distance remaining on a trip and the travel time
c. the amount of money spent and the number of shirts bought
d. the height of an eighth- grade student and the time to complete a puzzle
e. the amount of money owed on a computer and the time making payments
We need to find the positive associations in it.
Based on the definition of positive association,
The options (a) and (c) are the relationships that are in positive association.
Because while we look into the option (a),
When the traveling distance is increased then the time taken for it also increased.
Similarly in option (c),
While we increase the amount then the number of shirt we brought will also be increased.
The other options are not fit in this case.

Answer:
7/8
Step-by-step explanation:
This is a counting exercise. Think of the 200 persons that you have to separate into two groups:
1) A group that satisfies the condition of the question
2) A group that does not satisfy the condition
Then, count how many persons are in group 1, and divide that by the total (200). That is your probability.
For (i), you will find 175 persons in group 1. Even though there are many persons with not blue AND not fair hair, they are only in the group once, so don't count them double.
Then 175/200 = 7/8
In fact, you could reverse the question by counting how many people do not satisfy the condition. That group are the persons that have both blue eyes and fair hair. That is the only way to not satisfy the condition. That amount is 25, you can read it from the table.
The chance of being in that group is 25/200 = 1/8.
P(group 1) + P(group 2) = 1
So you now have two ways of getting your answer.
P(group 1) = 1 - 1/8 = 7/8.
