Answer:
Quick Answer it is A
Step-by-step explanation:
You have developed an angle bisector.
That means that JKM = LKM
B: is incorrect. The 1/2 should go on the angle on the left, not the one where it is
C: is incorrect. 1/2 of the given angle cannot be the same as the bisected angle.
D: is wrong. A bisected angle can't be twice as big as the given angle before it is bisected.
What would be the best first step to convert 5x-y=7 to slope intercept form?
Question 1 options:
Multiply both sides by -1
-5x from both sides
+5x to both sides
Subtract 7 from both sides
Answer:
-5x from both sides
Step-by-step explanation:
When converting an equation to slope-intercept form, you need to isolate the y. The first step in isolating the y is to remove 5x from both sides of the equation:
5x - y = 7
5x - 5x - y = 7 - 5x
-y = 7 - 5x
Now it's just -1y on one side of the equation.

What is 37% of 600?
ANSWER CORRECT
Answer:
the answer is 222
Answer:
222
Step-by-step explanation:
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
37/100 = X/600
X/600 = 37/100
X*600/600 = 37*600/100
X = 22200/100
X = 222
A researcher wants to construct a 90% confidence interval for the proportion of elementary school students in Seward County who receive free or reduced-price school lunches. A state-wide survey indicates that the proportion is 0.50. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.1?
Answer:
The sample size is [tex]n =68[/tex]
Step-by-step explanation:
The population proportion is [tex]\^ p = 0.50[/tex]
The margin of error is [tex]E = 0.1[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645 [/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{1.645 }{0.1} ]^2 * 0.50 (1 - 0.50 ) [/tex]
=> [tex]n =68[/tex]

Can someone please help me with this question I don’t understand it
Brand A: 32 Diapers, $8.99: about 28 cents per diaper
Brand B: 50 Diapers, $12.49: about 24 cents per diaper
You divide the amount of diapers by the money.
For example, 32 diapers/$8.99 equals about 28 cents per diaper and 50 diapers/$12.49 equals about 24 cents per diaper.
Brand B is the better deal since you save about 4 cents more.

If the data analyst hypothesizes that grocery sales are lower on Sunday than on other days, the null hypothesis would likely state that:
Answer:
The answer is "Grocery sales are lower or no different on Sunday than on other days"
Step-by-step explanation:
Its null hypothesis does not always consider any discrepancy between both the comparable qualities throughout facts and figures. Furthermore, researchers recommend also have lower or even no opposite transactions for Sunday than with other days, because there is no connection between grocery sales and Saturdays and Sundays.
Find 4cos2a, if
[tex] \cos(a) = \frac{ \sqrt{3} }{2} [/tex]
If you mean to find 4 cos(2a), then recall the double angle identity for cosine:

so that
4 cos(2a) = 4 (2 cos²(x) - 1) = 4 (√3 - 1)

The first coordinate of the point ( - 3, 2) indicates the point is located
Answer:
In the first coordinate
Step-by-step explanation:
For x = -3, the point is either located in 2nd or 3rd quadrant.
What is the general equation of a Straight line? What is a coordinate?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
A coordinate is represented as -
P(x, y)
where -
[x] is abscissa
[y] is ordinate
We have the following coordinate -
(-3, 2)
For x = -3, the point is either located in 2nd or 3rd quadrant
Therefore, for x = -3, the point is either located in 2nd or 3rd quadrant.

1200
Step-by-step explanation:
1680/1050 = 1920/x
1680x = 2,016,000
x=1200
There are 1200 vertical pixels.
Step-by-step explanation:This is a ratio problem, which uses ratios to relate different items in the question. In a ratio problem, it's important to remember to
1) Write the items in the ratio as a fraction.
2) Make sure that you have the same items in the numerator and denominator.
→ Step 1:The first step is to assign variables. Let x = vertical resolution of the 23" monitor.
Write the items in the ratio as a fraction.
[tex]\frac{horizontal}{vertical} = \frac{1680}{1050} = \frac{1920}{x}[/tex]
→ Step 2:Solve the equation.
Cross multiply:
[tex]1680*x = 1920 * 1050[/tex]
[tex]1680x=2016000[/tex]
Isolate variable x:
[tex]x=\frac{2016000}{1680}[/tex]

Solve for n in the following equation. A=P(1+n) show all your work
Answer:
A-1/P=n
Step-by-step explanation:
step 1. look at the parentheses and use inverse operations on both sides
A=P(1+n)
-1 -1
step 2. divide both sides by P
A-1=P(n)
/P /P
n= A-1/P
The value of n on solving the equation A = P (1 + n) is A / P - 1.
What is equation?An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.
Given:
A = P (1 + n),
Here we can solve the parentheses by using the distributive property as shown below,
A = P × 1 + P × n
A = P + nP
Transform as shown below,
nP = A - P
n = (A - P) / P
n = A / P - 1
Thus, the value of n is A / P - 1.
