Find the area [ a = bh ] of both then subtract.
16 * 20 = 320
11 * 14 = 154
320 - 154 = 166"
Best of Luck!
Answer:
45.24%
Step-by-step explanation:
Given that:
Correlation Coefficient (r) between number of hours a child play video games and number of minutes spent doing homework = - 0.74
The Coefficient of determination (r²) gives the percentage of variation in the dependent variable which can be explained by the independent variable.
Hence, the r² value = (-0.74)² = 0.5476 ; 54.76% which is about 55% variation in the number of minutes spent doing homework can be explained by the number of hours a child plays video games.
Hence the unexplained variance due to differences in children's ages is (100% - 54.76%) = 45.24%
N= 12 or - 12 I’m not sure I did it in my head
Answer: At 6% = $66,800
At 10% = $34,400
Step-by-step explanation:
Let S be his savings. He divided S into x that goes at 6% and y at 10%
As he put twiced as much at the lower-yielding one, x = 2y
Simple interest is given by: Amount x interest x time
This way I₁ = x . 0.06 . 1 = 0.06x
I₂ = y. 0.10 . 1 = 0.10y
As x = 2y, I₁ = = 0.06 . 2y = 0.12y
As we know that the annual interest was $7348
I₁ + I₂ = 7348
0.12y + 0.10y = 7348
0.22y = 7348
y = 7348/0.22
y = 33,400
As x = 2y, x = 2.33,400 = 66,800
This was he invested $33,400 and $66,800
Let
x-------> amount of money in their savings
accounts in May
we know that
In June, Liam deposited $ into his account
so
Balance Liam’s saving in June is equal to
------> equation
In June, Charlie increased the money in his account by%
Balance Charlie’s saving in June is equal to
------> equation
Equate equation and equation
$
therefore
the answer is
$
