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

Emma got 90% of the questions on her history test correct if she answered 27 questions correctly, how many questions did Emma get wrong?
There were (A) questions on the test so she got (B) questions wrong
Answer:
There were 30 questions on the test so she got 3 questions wrong.
Step-by-step explanation:
Given that:
Correct answers by Emma = 27
Percentage of correct answers = 90%
Let,
x be the total number of questions on test
90% of x = 27
[tex]\frac{90}{100}x=27[/tex]
[tex]0.9x=27[/tex]
Dividing both sides by 0.9
[tex]\frac{0.9x}{0.9}=\frac{27}{0.9}\\x=30[/tex]
There were 30 questions on the test.
Wrong answers = Total questions - Correct answers
Wrong answers = 30-27 = 3
Hence,
There were 30 questions on the test so she got 3 questions wrong.
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.
which function represents the relationship between x and y when y=16/5 and x=20
Answer:
y = (4/25)x
Step-by-step explanation:
We are given;
y = 16/5 and x = 20
Now if y varies directly with x, then we can say;
y = mx
Where m is constant of proportionality
This means that;
16/5 = 20m
Divide both sides by 20 to get;
(16/5) × 1/20 = m
16/100 = m
m = 4/25
Thus,the equation is:
y = (4/25)x
Write an equation to describe this situation using decimals. “Tessa bought x pounds of almonds. Lark (y) bought more than that”. PLEASE HELP!
Answer:
y = 1.6x
Step-by-step explanation:
y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.

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.

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.
