Answer:

Step-by-step explanation:

alright, lets get started.

The formula for weight and distance is :

w_{1}*d_{1}= w_{2}*d_{2}

Plugging the values of w1 as 150, d1 as 15, w2 as 300

150*15=300*d_{2}

dividing 300 in both sides

\frac{150*15}{300}=d_{2}

simplifying

d_{2}=\frac{15}{2}

d_{2}=7.5

Hence the answer is 7.5 feet.   :    answer

Hope it will help :)

3. The regression equation y = –0.414x + 106.55 approximates the percent of people in an audience who finish watching a document
BartSMP [9]

Answer:

The answer is 78%

Step-by-step explanation:

Step 1: The given regression equation y = -0.414x + 106.55

Step 2: The length of the film  = 70 minutes

Step 3: Plug in x = 70 in the given equation and find the value of y.

y = -0.414 (70) + 106.55

y = -28.98 + 106.55

y = 77.57

Y = 78%

Hope you will understand. :)

There are five boys to every nine girls in an introductory engineering course .if there are 364 students enrolled in the course
Nadusha1986 [10]

Answer:

234

Step-by-step explanation:

So what we know is that

5x+9x= students

This equation is saying that for every 5 boys there are 9 girls

we can then plug in 364 for the number of students and add like terms

This means that 14x=364

this means that x=26

This means that there are 26 sets of 5 boys and 9 girls

this means that there are

130 boys

234 girls
