Since she already had an integer you do (-9)-10=-19 Then you would do (-19)-8=-27 Then you do -27 + 14=-13 Then -13 + 12=-1 or you can just do -27 + 14 + 12=-1. That's the answer
24 = 4*6 = 2*2 * 2 *3
40 = 4*10 = 2*2 *2 *5
least common multiple is 2*2*2*3*5
120
Answer:
x=8
Step-by-step explanation:
so since the whole thing should equal 180, and the right triangle is 90,
(3x+11)+(5x+15)=90 then solve for that
8x+26=90
8x=64
divide both sides by 8
so x=8
then plug in 8 for the xs so c is 3(8)+11 --> 24+11 so m<C=35*
m<D=90*
5(8)+15 40+15 so m<E=55
Answer:
The P-value for this test is P=0.2415.
Step-by-step explanation:
We have to perform an hypothesis testing on the mean of alla account balances.
The claim is that the mean of all account balances is significantly greater than $1,150.
Then, the null and alternative hypothesis are:

The sample size is n=20, with a sample mean is 110 and standard deviation is 125.
We can calculate the t-statistic as:

The degrees of freedom fot this test are:

For this one-tailed test and 19 degrees of freedom, the P-value is:

61194.2707cm³
I suck at rounding so this is the answer not rounded
