Find the z-scores that correspond to each value and determine whether any of the values are unusual.
The z-score for 15 is
Solve for n.
39 = n − –12
n =
Answer:
Two negative make a positive so this equation is basically 39 = n + 12 so you need to subtract 12 from each side. This makes it n = 27

x and y are supplementary angles. y measures 88° What is the measure of x?
Answer:
x =92°
Step-by-step explanation:
Supplementary angles either of two angles whose sum is 180°.
So if y =88°
To get x, you subtract 180 from 88
Which would give you a difference of 92
To know of its Right you can add 88°+ 92° to see if you gwt a sum of 180°

Diego's age `d` is 5 more than 2 times his sister's age `s`. This situation is represented by the equation `d=2s+5`. If we know Diego's age, which equation will help us find his sister's age?
Answer: [tex]s=\dfrac{(d-5)}{2}[/tex].
Step-by-step explanation:
Given: d denotes Diego's age while s denotes his sister's age.
The situation is represented by the equation d=2s+5.
To find his sister's age we can write the above equation as [tex]s=\dfrac{(d-5)}{2}[/tex] [we first subtract 5 from both sides and then divide both sides by 2]
Hence, the required equation: [tex]s=\dfrac{(d-5)}{2}[/tex].

Anna received a gift card for $25 to an art store. The table shows the cost of the items.
Item Cost ($)
Bottle of Paint: 2.75
Brush: 1.09
Canvas: 7.99
Easel: 18.99
Palette: 4.50
She bought a canvas, two brushes, and three bottles of paint.
Which addition equation can be used to determine how much more money x Anna still has to spend?
A)
7.99 + (1.09) + (2.75) + x = 25
B)
7.99 + 3(1.09) + 2(2.75) + x = 25
C)
7.99 + 2(1.09) + 3(2.75) + x = 25
D)
7.99 + 2(1.09) + 3(2.75) + 25 = x
Answer:
7.99+2(1.09)+3(2.75)+x =25
Step-by-step explanation:
what's given are the prices of the canvas, brushes, and bottles of pain. 7.99 represents the one canvas Anna is buying, 2(1.09) represents the 2 brushes, and 3(2.75) represents the bottle of paints. Now what's left is x and x represents the amount of money left on the gift card. The gift card is $25 in total so that's why at the end of the equation it equals to $25.

What is Function?In mathematics, a function is a relationship between two values, x and y, from different sets—A and B. It connects inputs and outcomes.
Given a graph of a quadratic and a cubic equation. Sometimes you may figure out the answer by simply reading the presented problem. In order to determine the solution to the given problem, we must look at any (or any) point on the provided graph. Typically, we start by looking at the graph's x- or y-intercepts. Let's look at the following graph's y-intercept, where we can clearly understand what it looks like. We can tell that the graph's y-intercept is at -1 by looking at it. A position on the y-axis where the value of x is 0 is known as the y-intercept. Let's now examine the provided functions.
F(x) = a(x + 0.5) (x + 1.5)
g(x) = b(x+1)³
Where after putting the value at x = 0, b is 1 and a is 2.667.
Putting option in both equations only value which satisfying function F(x) = g(x) is 0.6, -0.6.
Therefore, values that are approximate solutions to the equation f(x) = g(x) are 0.6 and -0.6.

Answer and Step-by-step explanation:
[tex]6^{21}[/tex] is the answer.
3 times 7 is 21.
When exponents are being raised by an exponent, they will multiply together, so 7 being raised by the 3 will become 21, thus making the expression be 6 to the power of 21.
