Sounds like you want to find f(4) when f(x) = 6x+5

If so, then

f(x) = 6x+5

f(4) = 6(4)+5 ... replace x with 4

f(4) = 24+5

f(4) = 29

<h3>Answer: 29</h3>

A bank loaned out 12,000 part of it at a rate of 8% per year and the rest at 18% per year. If the interest recurved in one year
spin [16.1K]

Answer:

$11,600

Step-by-step explanation:

amount loaned at 8% and ($12,000 - x) = amount loaned at 18%

Write the equation: (change the percents to decimals: 8% = 0.08 and 18% = 0.18)

(0.08)x + (0.18)($12,000 - x) = $1,000

This expresses the total amount of earned interest in terms of the amounts of the loan, x and ($12,000 - x}.

0.08x + $2,160 - 0.18x = $1,000 Simplify and solve for x.

-0.1x = -$1,160 Divide both sides by -0.1

x = $11.600 The amount loaned at 8% interest.

A fair 6-faced die is tossed twice. Letting E and F represent the outcomes of the each toss (which are independent), compute the
andreyandreev [35.5K]

Answer:

(a)  \frac{1}{18}            (d)  \frac{1}{9}

(b) \frac{1}{2}               (e) \frac{1}{3}

(c) \frac{4}{9}               (f)  \frac{1}{12}

Step-by-step explanation:

On tossing a 6-face die twice the outcomes of E and F are:

{1, 2, 3, 4, 5 and 6}

And there are total 36 outcomes of the form (E, F).

(a)

The sample space of getting a sum of 11 is: {(5, 6) and (6, 5)}

The probability  of getting a sum of 11 is:

P(Sum 11) =\frac{2}{36} \\=\frac{1}{18}

(b)

The sample space of getting an even sum is:

{(1, 1), (1, 3), (1, 5), (2, 2), (2, 4), (2, 6) (3, 1), (3, 3), (3, 5), (4, 2), (4, 4), (4, 6) (5, 1), (5, 3), (5, 5), (6, 2), (6, 4), (6, 6)}

The probability  of getting an even sum is:

P(Even Sum)=\frac{18}{36}\\ =\frac{1}{2}

(c)

The sample space of getting an odd sum more than 3 is:

{(1, 4), (1, 6), (2, 3), (2, 5), (3, 2), (3, 4), (3, 6), (4, 1), (4, 3), (4, 5), (5, 2), (5, 4),     (5, 6), (6, 1), (6, 3) and (6, 5)}

The probability of getting an odd sum more than 3 is:

<em>P</em> (Odd Sum more than 3) =

=\frac{16}{36}\\=\frac{4}{9}

(d)

The sample space of (E, F) such that E is even and less than 6, and F is odd and greater than 1 is:

{(2, 3), (2, 5), (4, 3) and (4, 5)}

The probability such that E is even and less than 6, and F is odd and greater than 1 is:

P(Even E1) =\frac{4}{36} \\=\frac{1}{9}

(e)

The sample space of E and F such that E is more than 2, and F is less than 4 is:

E = {3, 4, 5 and 6}     F = {1, 2 and 3}

Then the total outcomes of (E, F) will be 12.

The probability such that E is more than 2, and F is less than 4 is:

P(E>2, F

(f)

The sample space of (E, F) such that E is 4 and sum of E and F is odd is:

{(4, 1), (4, 3) and (4, 5)}

The probability such that E is 4 and sum of E and F is odd is:

P(E=4, E+F = Odd)=\frac{3}{36} \\=\frac{1}{12}

Use the quadratic formula to solve the equation.
Sergeeva-Olga [200]

ANSWER

x =  \frac{ 5  - \sqrt{ 5} }{4}  \: or  \:  \: x =  \frac{ 5 +  \sqrt{ 5} }{4}

EXPLANATION

The given quadratic equation is

4 {x}^{2}  - 10x + 5 = 0

We compare this to

a {x}^{2}  + bx + c = 0

to get a=4, b=-10, and c=5.

The quadratic formula is given by

x =  \frac{ - b \pm \sqrt{ {b}^{2}   - 4ac} }{2a}

We substitute these values into the formula to get:

x =  \frac{ -  - 10 \pm \sqrt{ {( - 10)}^{2}   - 4(4)(5)} }{2(4)}

This implies that

x =  \frac{ 10 \pm \sqrt{ 100  - 80} }{8}

x =  \frac{ 10 \pm \sqrt{ 20} }{8}

x =  \frac{ 10 \pm2 \sqrt{ 5} }{8}

x =  \frac{ 5 \pm \sqrt{ 5} }{4}

The solutions are:

x =  \frac{ 5  - \sqrt{ 5} }{4}  \: or  \:  \: x =  \frac{ 5 +  \sqrt{ 5} }{4}

The value of the mean is 3 for normal curve C and the value of the mean is 4 for the normal curve D, and for both data standard deviation is the same.

<h3>What is a normal distribution?</h3>

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have a normal distribution curve shown in the picture.

For the normal curve C:

The value of mean = 3 (draw a vertical line in the middle of the curve)

For the normal curve D:

The value of mean = 4 (draw a vertical line in the middle of the curve)

For both data standard deviation is the same.

Thus, the value of the mean is 3 for normal curve C and the value of the mean is 4 for the normal curve D, and for both data standard deviation is the same.
