A linear function has the following format
y=mx + b
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Function f has two points, (-6,36) and (-4,26).
The slope is given by the change in y divided by the change in x, thus:
\(m= \frac{-26-(-36)}{-4-(-6)}=\frac{10}{2} = 5\)
therefore, f(x) =5x+ b
Point (-6, -36) means that when x= -6, y = -36, and this is used to find b.
-36 = 5*(-6) + b
b = -36 +30 = -6
so, f(x) = 5x - 6
Now, function g has two points, (-6, 15) and (-4, -11), and the slope is:
\(m= \frac{11-15}{-4-(-6)} = \frac{-4}{2} =-2\)
therefore, g(x)= -2x+b
Applying point (-6, 15):
15 = -2*(-6) + b
b = 15-12 = 3
so, g(x) = -2x + 3
The subtraction (f-g)(x) is:
(f-g)(x)= f(x)- g(x) = 5x - 6 -(-2x + 3)
5x - 6 + 2x - 3
7x - 9
Thus, the y-intercept is 7x-9

is the integer k divisible by 4 ? (1) 8k is divisible by 16. (2) 9k is divisible by 12.
Yes , the integer k is divisible by 4 and statement (1) alone is sufficient to determine that k is divisible by 4.
Given data ,
Let the equation be represented as A
Now , the value of A is
a)
To determine if the integer k is divisible by 4, let's analyze the given statements:
Statement (1): 8k is divisible by 16.
This means that 8k is a multiple of 16. Since 16 is divisible by 4, we can conclude that k must be divisible by 4 as well. Therefore, statement (1) alone is sufficient to determine that k is divisible by 4.
8k = 16
k = 2
b)
This statement does not provide direct information about the divisibility of k by 4. While 12 is divisible by 4, the fact that 9k is divisible by 12 does not guarantee that k itself is divisible by 4.
9k = 12
k = 12/9
k = 4/3
So , it is not an integer
In conclusion, statement (1) alone is sufficient to determine that k is divisible by 4. Statement (2) is not sufficient on its own.

some iq tests are standardized to a normal model with a mean of 100 and standard deviation of 16. what percent of iqs would be over 80?
Answer:
The percentage of IQs that would be over 80 is 68%.
Step-by-step explanation:
The percentage of IQs that would be over 80 is 68%.
This is because 68% of the population falls within one standard deviation of the mean on a normal distribution. In this case, the mean is 100 and the standard deviation is 16, so 68% of the population has an IQ between 84 and 116.
The remaining 32% of the population falls outside of one standard deviation of the mean. 16% of the population has an IQ below 84 and 16% of the population has an IQ above 116.
The mean is represented by the dotted line in the center of the graph. The standard deviation is represented by the two dotted lines on either side of the mean. The shaded area represents the 68% of the population that has an IQ between 84 and 116.

the owners of a supermarket chain are looking into the effectiveness of the supermarket's loyalty card program. specifically, they would like to know if the percentage of shoppers in their stores who use the loyalty card has changed from 63% in 2014. chloe works in the marketing department of the chain and is assigned to answer the owners' inquiry. she randomly selects 196 customers from various stores in the chain and finds that 114 use the loyalty card. what are the null and alternative hypotheses for this hypothesis test?
The null and different hypotheses for hypothesis test are
\(H_{0}\) : P =0.63 against \(H_{1}\) p \(\neq\) 0.63
Null hypotheses
Null hypothesis is usually what researchers or scientists try and confute, and if the null hypothesis is accepted, we have a tendency should modification our opinion, i.e., we have a tendency should modification our original opinion or statement so as to match the null hypothesis. H0 denotes the null hypothesis.Given that:
sample size (η)= 196
sample proposition (p^) = 114/196
Let p denote the population proportion of people who use a loyalty card.
The percentage of shoppers use loyalty cards in their stores has remittent from sixty-three in 2014. [That is, whether or not the proportion has shifted from zero to 1] .63]
Hence, the null and alternative hypothesis are
\(H_{0}\) : P =0.63 against \(H_{1}\) p \(\neq\) 0.63

Answer: Hey! The answer is 68.48 (rounded)
Step-by-step explanation:
These figures are similar. The perimeter and area of one are given. The perimeter of the other is also given. Find its area and round to the nearest tenth.
Perimeter= 20m
Area=19.6m^2
Perimeter=34m
What is the Area=
The area of the larger figure that is similar to the smaller one is: 28.2 m².
How to Find the Area of Similar Figures?Where A and B represent the areas of two similar figures, and a and b are their corresponding side lengths, respectively, the formula that relates their areas and side lengths is:
Area of figure A / Area of figure B = a²/b².
Given that the two figures are similar as shown in the image above, find each of their respective side lengths if we are given the following:
Perimeter of smaller figure = 20 m
Area of smaller figure = 19.6 m²
Perimeter of larger figure = 34m
Area of larger figure = x
Therefore:
20/34 = a/b
Simplify:
10/17 = a/b.
Find the area (x) of the larger figure using the formula given above:
10²/12² = 19.6/x
100/144 = 19.6/x
100x = 2,822.4
x = 2,822.4/100
x ≈ 28.2 m²

the approximate z-score that corresponds to a right tail area of is
The approximate z-score that corresponds to a right tail area of is standard normal distribution
In a right-tailed scenario, we are interested in finding the z-score that corresponds to a specific area or probability in the right tail of the standard normal distribution. This area represents the probability of obtaining a z-score greater than a certain value.
To determine the z-score corresponding to a right tail area, we can use either a z-table or statistical software. A z-table lists the cumulative probabilities or areas under the standard normal distribution curve. These tables provide the area to the left of a given z-score. However, since we are interested in the right tail, we need to find the complementary area or subtract the given area from 1.
For example, if the right tail area is 0.05, we need to find the z-score that corresponds to an area of 0.95 (1 - 0.05). We can use a z-table to find the z-score that has an area of 0.95 to its left. By looking up this area in the z-table, we can find the corresponding z-score.
Alternatively, statistical software or online calculators can also provide us with the z-score for a given right tail area. These tools allow you to input the area or probability directly and retrieve the corresponding z-score.
It's important to note that finding the exact z-score can be challenging because z-tables usually provide values rounded to two decimal places. However, these approximations are typically sufficient for most practical purposes.
