A heartbeat takes 0.8 seconds.How many sec is his written as a faction?

2 answers:

8 0

Because 8 is in the tenths place, we can write it as 8/10.

8/10 simplifies to 4/5 (divide numerator and denominator by 2)

Final answer: 4/5 seconds

Can someone please explain to me how to do numbers 2 and 3??

LenaWriter [7]

The answer to question 3 is 1 person orders chicken and the other 5 had steak dinner.

the way you work this out is you half 6 which is three and then do 3x14 and 3x17
3x14=42
3x17=51
42+51=93
this is too less so you have to do less of the cheaper meal (14) and more of the dearer one (17) so I went to 1x14 and 5x17
1x14=14
5x17=85
14+85=99
add these together and it makes 99

the answer to question 14 is 5 adults and 3 students

to do this you do exactly the same as how you do question 3

haiely created another problem involving 2 rectangles she says 2 rectangles have the same area javito says that her statement is

Verizon [17]

Her statement is possible, the first rectangle could be equal to the second because x is unknown so if x was 5in in the first rectangle and - 1 in the second rectangle both problems would look like this 2 in & 5 in and the second one 5in & (2 in = (-1 +3)).

The fitted regression is Sales = 832 − 28.2 Price. (a-1) If Price = 1, what is the prediction for Sales? (Round your answer to 1

almond37 [142]

Answer:

Part (a-1): The prediction for Sales is 803.8.

Part (a-2): The correct option is: An increase in price decreases sales.

Part (B): The prediction for sales is 211.66

Part (C): The intercept is meaningful as sales will be maximized when price is zero.

Step-by-step explanation:

Consider the provided regression:

Sales = 832 − 28.2 Price

(a-1) If Price = 1, what is the prediction for Sales?

Substitute Price = 1 in above regression.

Sales = 832 − 28.2 (1) = 803.8

Hence, the prediction for Sales is 803.8.

Sales (a-2) Choose the correct statement.

Here we can observe that as we increase the price, sales decrease.

Thus, the correct option is: An increase in price decreases sales.

(b) If Price = 22, what is the prediction for Sales?

Substitute Price = 22 in above regression.

Sales = 832 − 28.2 (22)

Sales = 832 − 620.4

Sales = 211.66

Hence, the prediction for sales is 211.66

Sales (c) Choose the right option.

As we increase the price, sales decrease that means the sales will be maximum if the price is 0.

The intercept is meaningful as sales will be maximized when price is zero.

1) the point where the x abd y axis meet 2) if m< A + m<D = 90, then <A and D are ____ angles 3) an angle formed by opp

Brums [2.3K]

1. The point where x and y axis meet is the intersect, origin of the coordinate system (0,0)

2. m<A and m<D = 90 then <A and D are complementary angles

3. 180 angle or linear rays

4. Obtuse angle measure more than 90

5. Segment of equal lengths are congruent segments

6. Lines that meet at a 90 angle are perpendicular
