A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table: Y

Nuetrik [128]

Answer:

Is an estimate of the average grams of salt used in 2012

Step-by-step explanation:

Let

x ---> the number of years since 2012

f(x) ---> is the total amount of salt ingested in grams

we have

$f(x)=52.3x+3.548$

This is a linear equation in slope intercept form

where

The slope is equal to

$m=52.3\ grams/ year$

The y-intercept or initial value is equal to

$b=3,548\ grams$

The y-intercept is the value of the function f(x) when the value of x is equal to zero

In this context, the y-intercept is the average amount of grams of salt ingested in the year 2012

The exact value of the average amount of grams of salt ingested in the year 2012 is 3,554 grams (see the data in the table)

Compare the exact value with the y-intercept

$3,554\ g\neq 3,548\ g$

therefore

3,548 grams Is an estimate of the average grams of salt used in 2012

The Baltimore Aquarium requires 3 adult chaperones for every 15 students on a field trip. How many chaperones would be needed fo

Elden [556K]

There would need to be 25 adult chaperones.

The ratio would be 3 adults to every 15 kids. 3:15
To find how many adults are needed for 125 kids you would simply divide.
125/5=25

Hope this helps! :)

count the numbers next to the 5, 6 & 7 = 10. then there are 2 numbers next to 8 less than 2

so 10 +2 = 12 students

What is the area of this triangle?

Ganezh [65]

Answer:

$\boxed{\bold{120 \ Units^2}}$

Step By Step Explanation:

Area Of Triangle: $\bold{\frac{1}{2}Base \ \cdot \ Height}$

Base: 10

Height: 24 (This triangle has a right angle, so we use the height based off of the 90° angle, which is 24)

Insert Numbers Into Equation

$\bold{\frac{1}{2}10 \ \cdot \ 24}$

$\bold{\frac{1}{2}}$ 10 = 5

$\bold{5 \ \cdot \ 24 \ = \ 120}$

➤ $\boxed{\bold{Mordancy}}$

Find the midpoint of each line segment

devlian [24]

Answer:

( $\frac{7}{2}$ , $\frac{1}{2}$ )

Step-by-step explanation:

For this you use the midpoint formula

$(\frac{x_{2} +x_{1} }{2} ,\frac{y_{2} +y_{1} }{2} )$

the points would be (2,1) and (5,2)

The midpoint would be ( $\frac{7}{2}$ , $\frac{1}{2}$ )
