Answer:

Predicted height: 57.42 inches

Residual: 2.58 inches

Step-by-step explanation:

Regression Equation

The regression equation for the height of the children (Hgt) and their age (Age) is given by the expression

Hgt = 24.3 + 2.76(Age)

We must compare the predicted value of the equation vs the real data point Age=12, Height=60

Computing the predicted height

Hgt = 24.3 + 2.76(12)

Hgt=57.42 inches

The residual is the difference between the real data point and the predicted value

R=60-57.42

R=2.58 inches

A taxicab company charges $3.10 plus $0.60 per mile. Carmen paid a fare of $10.90. Enter and solve an equation to find the numbe

9966 [12]

Answer:

13 miles

Step-by-step explanation:

The taxicab charges a fixed amount of $3.10 plus $0.60 per mile.

This can be modeled by the equation.

$f= 0.60m + 3.10$

where f is the total fare and m is the number of miles traveled.

If Carmen paid a fare of $10.90, then we substitute for f and solve for m.

$0.6m + 3.10 = 10.90$

$0.6m = 10.90 - 3.10$

$0.6m = 7.8$

$m = \frac{7.8}{0.6}$

$m = 13$

Therefore Carmen traveled 13 miles.

How many elements are in the set {x | x is an even prime number, x<150}?

Bond [772]

Answer:

The set {x | x is an even prime number, x<150} has 1 element.

Step-by-step explanation:

Prime Numbers: The numbers which have no factors other than 1 and the number itself are called prime numbers.

Even Numbers are those numbers which are completely divisible by 2.

So, the only EVEN PRIME NUMBER = 2

Now, Set = {x | x is an even prime number, x<150}

So, the set has {2} as its only element.

Hence, the total elements in the set is 1.

Or, the set {x | x is an even prime number, x<150} has 1 element.
