The zeros of a function are the values of for which the function is equal to zero. Enter a number in each blank to make true statements about the function ()=(2−6)(−4).
Answer:
Here we want to complete the blank to make the equality true:
( ) = (2 - 6)*(-4)
The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:
x = (2 - 6)*(-4)
We just need to find the value of x.
Then let's solve the right side:
x = (2 - 6)*(-4) = (-4)*(-4)
Remember the rule of signs:
(-)*(-) = (+)
x = (-4)*(-4) = 4*4 = 16
Then we need to complete the blank with the number 16
(16) = (2 - 6)*(-4)
Describe the trend/correlation
shown in the scatter plot below
Answer:
Negative correlation.
Step-by-step explanation:
Negative correlation means that as x increases, y decreases
Positive correlation means that as x increases, y also increases.
No correlation means that neither of the two above cases happens.
In the graph, we can see that on the right (when x is negative) the general y values are larger.
As x increases, the y-values decrease.
(Particularly, we could adjust these data with a linear equation with a negative slope)
Then this is a negative correlation.

some patients participated in a clinical trial for a new drug to treat osteoporosis. A patient is selected at random. The probability that the patient had no change in his bone mass density is 7/13, the probability that he had a slight reduction in his bone mass density is 1/k and the probability that he had a significant reduction in his bone mass density is 1/2k. Find the value of k
Answer:
k = 3.9
Step-by-step explanation:
Since the three possible outcomes are given. Therefore, the sum of all the probabilities of the three possible outcomes will be equal to one:
[tex]\frac{7}{13} +\frac{1}{k}+ \frac{1}{2k} = 1 \\\\\frac{1}{k} \frac{1}{2k} =1-\frac{7}{13}\\\\\frac{3}{2k} \frac{5}{13}\\\\2k = \frac{(13)(3)}{5}\\\\k = \frac{39}{(5)(2)}\\[/tex]
k = 3.9

What is the formula to find the probability of an event?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favourable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Now, probability = 55/340 =11/68
Therefore, the probability that a randomly selected senior voted for an eagle mascot is 11/68.

Calculate x
Answer:
x = 31
Step-by-step explanation:
The two triangles are similar, so [tex]\triangle{NPO} \sim \triangle{YZO}[/tex].
Vertex N matches up with vertex Y.
Vertex P matches up with vertex Z.
Vertex[tex]\frac{NO}{YO}=\frac{1}{4}\\\\\frac{x}{124}=\frac{1}{4}\\\\4x=124\\\\x=31[/tex] O matches up with itself.
Corresponding sides are in proportion. To find the proportion between the two triangles, you use known sides from each.
[tex]\frac{NP}{YZ}=\frac{23}{92}=\frac{1}{4}[/tex] meaning the small triangle is 1/4 the size of the large one.
To find x , notice that it is side NO which corresponds to side YO from the large triangle.
The price of a snowsuit is reduced by $28.38.
This is a discount of 33%.
a) What is the regular price of the snowsuit?
b) What is the sale price of the snowsuit, including taxes?
Answer:
(a) s = the original price = $28.38 / 0.67 = $42.36
Step-by-step explanation:
Let s represent the original price of the snowsuit.
If $28.38 is a discount of 33% from the original price, then (1.00 - 0.33)s = $28.38, or 0.67s = $28.38.
(a) s = the original price = $28.38 / 0.67 = $42.36
(b) if taxes are 7% then the sale price is (1.07)($42.36) = $45.32.
Of course, if the tax rate is other than 7%, the total sale price will be different.

A field has a length of 260 meters and a width of 500 meters. Part of the field, 50 meters by 200 meters, is paved for a parking lot. How much of the area remains unpaved?
Answer: 120,000 meters²
Step-by-step explanation:
First find the area of all the land both paved and unpaved:
= Length * Width
= 260 * 500
= 130,000 meters²
The find the area paved:
= 50 * 200
= 10,000 meters²
The area left unpaved:
= Total area - Paved area
= 130,000 - 10,000
= 120,000 meters²
