Answer:

x=10

Step-by-step explanation:

1/2x+4=9

subtract 4 from both sides

1/2x=5

multiply both sides by 2 to get x by itself

x=10

Answer:

1/2x+4=9 is x=1/10

Answer:

4

Step-by-step explanation:

simple

Volume = PI x r^2 x h

r -s 1/2 the diameter ( 20/2 = 10)

Volume = 3.14 x 10^2 x 5

Volume = 3.14 x 100 x 5

Volume = 3.14 x 500

Volume = 1570 cubic meters

The answer is 1570.8

Condense the logarithm on the right side:

[tex]3\log_b(p)-\left(2\log_b(t)+\dfrac12\log_b(r)\right)[/tex]

[tex]n\log_b(m)=\log_b(m^n) \implies \log_b(p^3)-\left(\log_b(t^2)+\log_b\left(r^{\frac12}\right)\right)[/tex]

[tex]\log_b(m)+\log(n)=\log_b(mn) \implies \log_b(p^3)-\log_b\left(t^2r^{\frac12}\right)[/tex]

[tex]\log_b(m)-\log(n)=\log_b\left(\dfrac mn\right) \implies \log_b\left(\dfrac{p^3}{t^2r^{\frac12}}\right)[/tex]

So,

[tex]x=\dfrac{p^3}{t^2r^{\frac12}}[/tex]

and [tex]r^{\frac12}=\sqrt{r}[/tex], which makes (4) the correct choice.

Answer:

Third choice, 3/4

Step-by-step explanation:

There's 3 lines in the middle before it's the number 1, if u count 1 into the lines then there's 4, 1 divided by 4 is 0.25 or 1/4, so each small line is going up or down by 1/4. So it's 0 -> 1/4 -> 2/4 -> 3/4 which is A -> 4/4 which is 1

So A is 3/4

Answer:

We can think in this situation as:

There is 10% (or a probability equal to 0.1) where the citrus grower's profit will be reduced by $15,000

There is 10% (or a probability equal to 0.1) where the citrus grower's profit will be reduced by $25,000

And in the remaining 80% (or a probability equal to 0.8), the profit does not change.

Then the expected value for the total profit can be written as:

EV = $100,000 + ( 0.1*(-$15,000) + 0.1*(-$25,000) + 0.8*$0)

     =  $96,000

In the case where the citrus grower spends $5000 to protect the fruits against possible bad weather, there is a 100% that is profit will not change, but he must pay $5,000

Then his profit will be:

P = $100,000 - $5,000 = $95,000

So in this case, the profit is $1000 less than the expected profit in the prior case. So the scenario where he does not buy the protection has a larger expected profit, which may mean that is better to not buy it (in a straight mathematical point of view)

One also could think that  the values are really close together, so buying the protection does not mean a big change, and increases the security

Step-by-step explanation:

Answer:

Subtraction property of equality

Step-by-step explanation:

Given the equation;

2x + (x+5) = 41

open the parenthesis;

2x+x + 5 = 41 (Associative property)

3x+5 = 41

Subtract 5 from both sides

3x + 5 = 41

3x + 5- 5 = 41 - 5 (Subtraction property of equality)

3x = 36

Divide both sides by 3;

3x/3 = 36/3

x = 12 (Division property of equality)

Hence the required property is Subtraction property of equality

Answer: 4

Step-by-step explanation:

If I had 3 to the power of 4, I would multiply it by three 4 times. (3x3x3x3=81) The exponent is telling me how many times to use 3 in multiplication

Answer:

About 42 cents

Step-by-step explanation:

What we know:

An 18-count variety pack of Taki's chips costs $7.49.

To find the unit rate divide 7.49 by 18, and round to the nearest cent.

7.49/18

Before we do that, what is 749/18?

749/18 = 41 11/18

Divide that by 100 to get your answer

41.61111/100 = 0.4161111, which rounds to 42 cents.

Answer:

9) x = 62 10) x = 61 11) x = 7

Step-by-step explanation:

9) x + 118 = 180

- 118. - 118

x = 62

10) 2x + 3 + x - 6 = 18

Add like terms

x = 61

11) x + 16 = 4x - 5

x = 7

Answer: For this one, I'll use y=mx+b because that equation make the most sense in this scenario.

A) X is the number of hours, and 15, or b is the tip

B) y= 30x + 15.

Answer:

It is a function

Step-by-step explanation:

A function is of the form:

[tex]\left[\begin{array}{c}x_1&x_2&x_3\\-&-&-\\x_n\end{array}\right][/tex]            [tex]\left[\begin{array}{c}y_1&y_2&y_3\\-&-&-\\y_n\end{array}\right][/tex]

Where each of the x values must be distinct.

The x values are referred to as domain while the y values are called range.

Having said that, the given data can be represented as follows:

[tex]\left[\begin{array}{c}-3&1&6\\7&12\end{array}\right][/tex] ----------- [tex]\left[\begin{array}{c}7&-8&-6\\-8&2\end{array}\right][/tex]

From the representation above, none of the x values are repeated.

Hence, it is a function

Answer:

Step-by-step explanation:

Following are the solution to the given points:

Assume A, P, and B is the masses of apples, pears, and basket, respectively.

[tex]\to W = 4A + 6P + B[/tex]

Calculating the mean of W:

[tex]\to \bold{W = E(W) }[/tex]

         [tex]\bold{= E(4A + 6P + B)} \\\\ \bold{= 4E(A) + 6E(P) + E(B)}\\\\\bold{= 4 \times 4.72 + 6 \times 5.41 + 13.52} \\\\ \bold{= 18.88 + 32.46 + 13.52} \\\\ \bold{= 64.86 }[/tex]

Calculating the variance of W:

[tex]\to \bold{W=Var(W)}\\\\[/tex]

         [tex]\bold{= Var(4A + 6P + B)}\\\\ \bold{= 42 Var(A) + 62 Var(P) + Var(B)}\\\\\bold{= 16 \times 0.22 + 36 \times 0.182 + 1.882}\\\\ \bold{= 3.52 + 6.552 + 1.882}\\\\ \bold{= 5.3408}[/tex]

Calculating the standard deviation of W:

[tex]\to \bold{W= \sqrt{5.3408}= 2.311017}[/tex]

The linear combination of Normal random variables is known to follow the normal distribution.

[tex]\to \bold{W \sim N(64.86 , 2.311017)}[/tex]

Calculating the Probability of the Total Weight is more difficult.[tex]\to \bold{67 = P(W > 67)}[/tex]  

         [tex]\bold{= P[ Z > \frac{(67 - 64.86)}{ 2.311017}]}\\\\\bold{= P[Z > 0.93]}\\\\\bold{= 0.1762}[/tex] (Using Standard Normal distribution)

Therefore, the final answer is "64.86, 2.311017, and 0.1762".
