Answers
The normal curve with a mean of 0 and standard deviation of 1 is called (D) the z-value.
What is a standard score (z-value)?The z-score value indicates how many standard deviations you are from the mean. A z-score of 0 indicates that the data is on the mean. A positive z-score indicates that the raw score exceeds the mean average. For example, a z-score of +1 indicates that it is one standard deviation above the mean. The number of standard deviations by which the value of a raw score (that is, an observed value or data point) is above or below the mean value of what is being observed or measured is referred to as the standard score in statistics. Raw scores that are higher than the mean have positive standard scores, while those that are lower than the mean have negative standard scores.Therefore, the normal curve with a mean of 0 and standard deviation of 1 is called (D) the z-value.

Answers
The matching between the expressions and their derivatives is as follows: a - 4, b - 1, c - 3, d - 2.
a. The expression "e + 1" corresponds to f(x) = e er + 1. To find its derivative, we differentiate the expression with respect to x. The derivative of f(x) is f'(x) = e er + 1. Therefore, the derivative matches with option 4, f'(2) = e er + 1.
b. The expression "e²" corresponds to f(x) = e². The derivative of f(x) is f'(x) = 0, as e² is a constant. Therefore, the derivative matches with option 1, f¹(e) = 0.
c. The expression "e" corresponds to f(x) = e. The derivative of f(x) is f'(x) = e. Therefore, the derivative matches with option 3, f'(2) = e.
d. The expression "e2x" corresponds to f(x) = e2x. To find its derivative, we differentiate the expression with respect to x. The derivative of f(x) is f'(x) = 2e2x. Therefore, the derivative matches with option 2, f'(2) = 2e2x.
In summary, the matching between the expressions and their derivatives is: a - 4, b - 1, c - 3, d - 2.

Answers
The solution to the system of equations is (1.6,-1.6).
What is the system of equations?
Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
Here, we have
Given equations:
y = 1.5x - 4....(1)
y = -x....(2)
Substitute y = -x in the first equation
-x = 1.5x - 4
Collect like terms
-1.5x - x = -4
This gives
-2.5x = -4
Divide both sides by -2.5
x = 1.6
Substitute x = 1.6 in y = -x
y = -1.6

can you help me?????
Answers
Answer:
Step-by-step explanation:
I don't do this question the way it is outlined. My way is a bit shorter.
The general equation is y = mx + b
You want the slope to be - 1/5 which you just read from the given equation.
So, so far you have y = -1/5x + b
Now for the point which is (5,-4)
x = 5
y = - 4
-4 = -1/5 * 5 + b
-4 = -1 + b
b = -4 + 1
b = - 3
the equation is y = -1/5 x - 3
===========================
Now let's do it your way.
y - y1 = m(x - x1)
x1 = 5
y1 = - 4
m = - 1/5
y - - 4 = -1/5(x - 5
y + 4 = -1/5x + 1 Take 4 from both sides
y = -1/5 x + 1 - 4
y = -1/5 x - 3

Given that angle B is in standard position, the terminal side is in quadrant III and sin B=-5/13, evaluate the following functions:
csc B = b) cot B = c) cos B = d) sec B = e) tan B =
Answers
Given that sin B = -5/13 and angle B is in quadrant III, we can use the Pythagorean identity to find the value of cos B:cos² B + sin² B = 1
cos² B + (-5/13)² = 1
cos² B = 1 - 25/169
cos² B = 144/169
cos B = -12/13 (since cos B is negative in quadrant III)a) To find csc B, we can use the reciprocal identity:
csc B = 1/sin B
csc B = 1/(-5/13)
csc B = -13/5b) To find cot B, we can use the quotient identity:
cot B = cos B/sin B
cot B = (-12/13)/(-5/13)
cot B = 12/5c) To find cos B, we have already calculated it above:
cos B = -12/13d) To find sec B, we can use the reciprocal identity:
sec B = 1/cos B
sec B = 1/(-12/13)
sec B = -13/12e) To find tan B, we can use the ratio identity:
tan B = sin B/cos B
tan B = (-5/13)/(-12/13)
tan B = 5/12Therefore, the values of the trigonometric functions for angle B in standard position with terminal side in quadrant III and sin B = -5/13 are:
a) csc B = -13/5
b) cot B = 12/5
c) cos B = -12/13
d) sec B = -13/12
e) tan B = 5/12

The deer ate ସ ହ x N / 7 of the peppers in total.
What is multiplication?
Calculating the sum of two or more numbers is the procedure of multiplication. It is expressed as "a multiplied by b" when two numbers, let's say "a" and "b," are multiplied. Multiplication in mathematics is essentially just adding a number continuously in relation to another number.
Let's assume that the same amount of peppers were planted in each yard. If the deer ate ସ ହ of the peppers from 7 yards, that means they ate ସ ହ/7 of the peppers from each yard.
To find out how much of the peppers they ate in total, we can multiply the amount they ate from each yard by the total number of yards. Let's say there were N yards in the neighborhood. Then the total amount of peppers the deer ate would be:
Total amount of peppers = (ସ ହ/7) x N
We don't know the value of N, but we can simplify the expression by multiplying ସ ହ/7 by N:
Total amount of peppers = (ସ ହ x N) / 7
Therefore, the deer ate ସ ହ x N / 7 of the peppers in total.
