Plug in 10 for z. Remember to follow PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)
7 + 10/2
Divide 10 with 2
10/2 = 5
Add 5 with 7
5 + 7 = 12
12 is your answer
hope this helps

Step-by-step explanation:
For 180 degrees rotation, the rule is (x, y) -----> (-x, -y)
Choose a point
Point C (6,2) -----> (-6,-2)
shift that point two down and it lines up with C'
Answer: $72
Step-by-step explanation:
Simple interest (I) is calculated as Principal × Rate × Time.
From the question, Principal = $800
Rate =3% = 3/100= 0.03
Time =3 years
Slot in the values into the formula;
I = 800 x 0.03 x 3
I= $72
I hope this is clear
Answer:
B
Step-by-step explanation:
When testing hypothesis to make a conclusion, you must find sufficient evident to reject the null hypothesis in favor of the alternative hypothesis. The null hypothesis must fail in order to accept the alternative. Failing to reject is not enough information. Since this is the case then options C and D are false statements and cannot be true. Both state that if you reject the null then the alternative is false or can't be supported. The opposite is true. Option A is also false since you cannot accept the null. You can only fail to reject it. If this is true then the alternative certainly cannot be accepted. Option B must be correct and the statement (thought not listed here) must be true.
A. This statement is false. A true statement is, "If you decide to accept the null hypothesis, then you can support the alternative hypothesis."
B. This statement is true.
C. This statement is false. A true statement is, "If you decide to reject the null hypothesis, then you can't support the alternative hypothesis."
D. This statement is false. A true statement is, "If you decide to reject the null hypothesis, then you can assume the alternative hypothesis is false."
