If the CPI for 1989 was 124, the rate of the inflation between the base period and 1989 was 24%!
Answer:
i think you just multiply 20x60= 120
Answer:
d.) (4,6)
Step-by-step explanation:
(-y,x) is the formula for a 90 counter-clockwise rotation.
So, it's (4,6)
Answer:
1. Draw 4 in the tens box, and 3 in the ones box. There are 4 tens and 3 ones. The total amount is 43 cents.
2. The total value is 26. There are 2 dimes. Each dime is worth 10 cents. 2 x 10 = 20. There are 6 pennies. Each penny is worth 1 cent. 6 x 1 = 6. 20 + 6 = 26 cents.
3. There are 3 tens and 3 ones.
4. The total value is 33 cents.
5. 50, 55, 60, 65.
6. 70, 80, 90, 100.
7. 50, 60, 70, 80.
Answer: a.) About 54% of the variation in distance that the driver can see is explained by a linear relationship with the driver's age.
b.) The correlation coefficient, r, is -0.736.
Step-by-step explanation:
The coefficient of determination is denoted which gives the percent of the variance in the dependent variable that is predictable from the independent variable.
Given,
That means 54% of the variation in distance that the driver can see is explained by a linear relationship with the driver's age.
Also, , where r determines the correlation coefficient.
As driver;s age increases the distance he can see decreases, so there is a negative correlation between them.
So r= -736.
Hence, The correlation coefficient, r, is -0.736.
So, the correct options are a.) and b.)
