Answer: he invested $15000 in part 1 and $60000 in part 2
Step-by-step explanation:
Let x represent the amount of money invested in part one.
Let 4x represent the amount of money invested in part 2 .
Total amount of money invested in part 1 and part 2 is
x + 4x = 5x
The formula for simple interest is expressed as
I = PRT/100
Where
P is the principal or initial amount.
T is the duration in years
R is the number rate.
For part 1
R = 7%
T = 1 year
P = x
I = (x × 7 × 1)/100 = 0.07x
For part 2,
R = 11%
T = 1 year
P = 4x
I = (4x × 11 × 1)/100 = 0.44x
if the total annual income from interest is 7650. This means that
0.44x + 0.07x = 7650 - - - - - - - -2
0.51x = 7650
x = 7650/0.51
x = 15000
Amount invested in part 1 is $15000
Amount invested in part 2 is 4×15000 = $60000
Considering the box and whisker plot, it is found that the number of dogs that weigh more than 35 pounds is given by:
C. 75
<h3>What does the box plot shows?</h3>
It shots the first quartile, the median and the third quartile. In this problem:
- The first quartile is of 35.
- The third quartile is of 70.
The first quartile of 35 means that 25% of the measures are less than 35, and 75% are more, hence, out of 100:
0.75 x 100 = 75
Which means that option C is correct.

Step-by-step explanation:
The area of the polygon is 51cm².
Answer:
No
Step-by-step explanation:
We can not determine that the low test scores are caused by sleep deprivation. Because there are many factors that can affect on a student's test score such as:
- not carefully review all the lesson before the test
- the feeling of nervous in the exam room
- poor academic ability
- ....so on
So, getting less than 8 hours of sleep is just one of the independent variables determining the test score, it is not a strong correlation.
The answer is 3.5 and -3.5. 3.5 will stay the same and -3.5 will turn to 3.5
