Answer:
0.0287
Step-by-step explanation:
Using the binomial probability relation :
p = 0.76
q = 1 - p = 1 - 0.76 = 0.24
P(x = x) = nCx * p^x * q^(n-x)
P(x = 2) = 6C2 * 0.76^2 * 0.24^4
P(x = 2) = 15 * 0.76^2 * 0.24^4
P(x = 2) = 0.02874507264
P(x = 2) = 0.0287

A bank loaned out $15,000, part of it at the rate of 7% per year and the rest at 17% per year. If the interest received in one year totaled $2000, how much was loaned at 7%?
How much of the $15,000 did the bank loan out at 7%?
9514 1404 393
Answer:
$5,500
Step-by-step explanation:
Let x represent the quantity loaned at 7%. Then the amount loaned at 17% is (15000-x), and the total interest is ...
0.07x +0.17(15000 -x) = 2000
-0.10x = -550 . . . . . . . . . collect terms, subtract 2550
x = -550/-0.10 = 5500 . . . . divide by the coefficient of x
The bank loaned $5,500 at 7%.

The amount of time (in minutes per day) spent on social media for a sample of 10 teens has a mean of 186.7 and a sample standard deviation of 19.99. An independent sample of 8 older adults has a mean of 93.5 minutes with a sample standard deviation of 32.01. Assume that the time spent on social media is approximately normally distributed for each group. a) Determine the value of the test statistic to test H subscript 0 colon space mu subscript t e e n end subscript equals mu subscript o l d e r end subscript against H subscript A colon space mu subscript t e e n end subscript not equal to mu subscript o l d e r end subscript. b) Determine the p-value or critical value for this test at alpha equals 0.05. c) What is your conclusion about whether the two age groups spend the same average amount of time on social media

A right triangle has a leg of 12 cm and a hypotenuse of 19 cm.
What is the length of the other leg?
Round to the nearest tenth.
-----------------------------------------
7.0 cm
14.7 cm
22.5 cm
217.0 cm
Answer:
14.7 cm
Step-by-step explanation:
Using Pythagoras Theorem,
The length of the other leg
[tex] = \sqrt{ {19}^{2} - {12}^{2} } [/tex]
[tex] = \sqrt{217} [/tex]
[tex] = 14.730919...[/tex]
= 14.7 cm (rounded to the nearest tenth)

What is the measure of angle B in degrees?
Answer: how do I delete my answer?
Step-by-step explanation.
Here's the solution,
=》 C + 112° = 180°
( they form linear pair )
=》 C = 180° - 112°
=》C = 68°
And we know, measure of exterior angle if a triangle is equal to the sum of measures of the opposite interior angles,
So,
=》B = C + 51°
=》B = 68° + 51°
=》B = 119°

Which of the following represents a coefficient from the expression given?
5x - 21 + x2
Answer:
1 or 5
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 5x would be 5.
The coefficient of x^2 would be 1.
