<u><em>Answer: =204 *The answer should be have a positive sign.*</em></u>
Step-by-step explanation:
This question it's about PEMDAS. This lesson it's about order of operation. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It must be go left to right.
do parenthesis first.
12(8+9)
9+8=17
multiply left to right.
12*17=204
=204
Hope this helps!
Thanks!
Have a great day!
If you calculate the problem correctly you should end up with:
(A)-(3)
Which equals:
= -3
Hope this helps... have a good day!
Answer:
R = 0.862
Strong positive relationship
Step-by-step explanation:
Given the data:
Test Chemistry Student Score,
x Grade, y
1 2 3 4 5 6 7 8 9 10 11 12
Score,x = 65 50 55 65 55 70 65 70 55 70 50 55
Grade, y = 85 74 76 90 85 87 94 98 81 91 76 74
Using technology :
The CORREL function in excel, calculators will give accurate value of the correlation Coefficient between two variables, x and y. The correlation Coefficient obtained using technology is : 0.862
The correlation Coefficient value ranges between (-1 and 1) with values closer to either - 1 or 1 reflecting stronger relationship. A value of 0 means there is no relationship between the variables. Negative values indicate negative relationships while positive indicates positive association between the variables.
Therefore. With a correlation Coefficient of 0.862, the correlation Coefficient can be interpreted as meaning that ; there is a strong positive relationship between score and grade.
you know he made 5 deliveries for $16 each. 5*16=80. So to find his salary you have 215-80=$135.
So he makes $135 no matter what plus $16 times the number of deliveries.
so, S=16d+135
Answer:
-4, 3
Step-by-step explanation:
To find x intercepts, set y equal to 0;
0 = 5(x+4)(x-3); when x = -4 or x = 3, y will be zero (these are the x intercepts),
