Answer:
D) 200
Step-by-step explanation:
To find what x equals you have to use the expression:
is over of equals percent over 100
In this problem you are given the percent, 65%, and the is, 130.
So we are trying to find the of so you would substitute of with x.
So 130/x = 65/100
Now you would do Cross Product Property to find x.
So 130*100 = 13000
65*x = 65x
65x = 13000
65/65 = 1
13000/65 = 200
x = 200
So 65% of 200 is 130
Answer:
She can make 19 cupcakes!!
Have an amzing day!!!!!
You should expect about 2400 successes because as a percent .4=40%
Answer:
a) strong negative linear correlation.
b) Weak or no linear correlation.
c) strong positive linear correlation.
Step-by-step explanation:
The correlation coefficient r measures the strength and direction (positive or negative) of two variables. The correlation coefficient r is always between -1 and 1. When the coefficient r is negative then the direction of the correlation is downhill (negative) and when it's positive then it's an uphill correlation (positive). Similarly, as the coefficient is closer to -1 or 1 the correlation is stronger, with zero being a non linear relationship.
Now back to the question:
a) Near -1: as we said before, this means an strong negative (-1) linear correlation.
b) Near 0: weak or no linear correlation (we cannot say if its positive or negative because we don't know it it's near zero from the right (positive numbers) or the left (negative numbers)
c) Near 1: strong positive (close to +1) linear correlation
