Answer:15-2x=-45

15-2=13

13=-45

Step-by-step explanation:

I hope that helps you!

Answer:

x = 30

Step-by-step explanation:

15 - 2x = -45

+ 2x to both sides

15 = 2x - 45

+ 45 to both sides

60 = 2x

divide both sides by two

x = 30

x=  12.528

*rounded is 12.53 or 12.5

Step-by-step explanation:

7.3 ^2 + x^2 = 14.5^2

53.29 + x^2 = 210.25

-53.29            -53.29

x^2= 156.96

x= 12.528

Answer:

Is there diagram for this?

Answer:

x = 12.5

Step-by-step explanation:

From the diagram,

Applying

tanФ  = Opposite/Adjacent...................... Equation 1

From the diagram,

Given: Opposite = 16, Adjacent = x, Ф = 52°

Substitute these values into equation 1

tan52° = 16/x

make x the subject of the equation

x = 16/tan52°

x = 16/1.27994

x = 12.5.

Answer:

Equidistant

Step-by-step explanation:

When we have a point lying on the angle bisector, it stands at an equal distance from the two sides of the angle

The purpose of the angle bisector is to divide the angle into two different equal parts

So, for a point to lie on this, it means it of the same distance from the two points of the angle

5/38

Step-by-step explanation:

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.

The numerator is the number above. While the denominator is the number below

an example of a fraction =  [tex]\frac{4}{5}[/tex]

4 is the numerator while 5 is the denominator

Answer:

Of the 777 rounds of the game in about 368 the ball will land in a red slot.

Step-by-step explanation:

Since a roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green, and in each round of the game, a ball is tossed in the spinning wheel and lands in a random slot, supposing we watch 777 rounds of this game, to determine the approximate number of rounds where the ball lands in a red slot, the following calculation must be performed:

383838 = 100

181818 = X

181818 x 100/383838 = X

18,181,800 / 383838 = X

47.3684 = X

100 = 777

47.3684 = X

47.3684 x 777/100 = X

36,805.24 / 100 = X

368.05 = X

Therefore, of the 777 rounds of the game in about 368 the ball will land in a red slot.

Answer:

Standard Error is increased.

Step-by-step explanation:

Type 2 error is failure to reject a false null hypothesis. This is a 'false negative' result of hypothesis testing, represented by beta 'β'.

Power of test is 1 - β, which shows probability of accurately stating  a null hypothesis false, when it is actually false.

Increased sample size increases the power of test accuracy, hence reduces type 2 error. Increased level of significance implies higher probability of rejecting a true null hypothesis, ie type 1 (false positive) error. So, it decreases type 2 error.

Standard Error increase implies lower level of t statistic , ie = (x - u) / (s / √ n) Lower the t value, higher is the probability of not rejecting null hypothesis, which implies higher chance of type 2 error.

Type II error is 1 - power of the test. The factor that can alone make the type II error to increase is: Option C: The standard error is increased.

Firstly the whole story starts from hypotheses. The null hypothesis is tried to reject and we try to accept the alternate hypothesis.

The probability of committing the type I error is called the significance level of the hypothesis test.

And the more we increase the level of significance, the less area the test statistic gets to fall in, and its chances of falling in region outside level of significance increases, which makes us to reject the null hypothesis more probable, thus, decreasing its chance of tagging as negative, not mattering if true or false.
Thus, increasing level of significance increases the type I error but decreases the type II error.

If it is increases, the likely area for test statistic falling increases, thus, increasing probability of tagging the null hypothesis tagging to be true, so increasing result of test being declared negative, thus, increasing type II error.

Increasing sample size increases statistical power, thus, decreasing the type II error.

Thus, for the given case, as the sampling size is increased, the type II error will decrease, as the significance level is increased, the type II error will decrease, and as the standard error is increased, the type II error will increase with it.

Thus, out of the given factors, only the last factor (increasing the standard error) makes the type II error to get increased.

Thus, the factor that can alone make the type II error to increase is: Option C: The standard error is increased.

Answer:

Robert will have $481 more in his account than Cooper.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Continuous compounding:

Similar to compound interest:

[tex]A(t) = P(1 + r)^t[/tex]

Cooper:

Cooper invested $3,100 in an account paying an interest rate of 2% compounded quarterly. This means that [tex]P = 3100, r = 0.02, n = 4[/tex]

After 12 years is A(12). So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(12) = 3100(1 + \frac{0.02}{4})^{4*12}[/tex]

[tex]A(12) = 3938.5[/tex]

Cooper will have $3938.5 in his account.

Robert:

Robert invested $3,100 in an account paying an interest rate of 3 % compounded continuously. So [tex]P = 3100, r = 0.03[/tex].

After 12 years.

[tex]A(t) = P(1 + r)^t[/tex]

[tex]A(12) = 3100(1 + 0.03)^{12}[/tex]

[tex]A(12) = 4419.9[/tex]

Robert will have $4419.9 in his account.

How much more money would Robert have in his account than Cooper, to the nearest dollar?

4419.9 - 3938.5 = 481.4

To the nearest dollar, Robert will have $481 more in his account than Cooper.

Answer:

8p=c

Step-by-step explanation:

For questions like this, it isn't asking for a numerical answer or anything complicated. It's mainly just using common sense and figuring out what you would do if you had actual numbers instead of variables. You would multiply the amount of pounds (p) by the cost per pound of $8, and that would be your answer (c). I hope I could help.

Answer:

Let's solve for h.

y=a3x−h+k

Step 1: Flip the equation.

a3x−h+k=y

Step 2: Add -a^3x to both sides.

a3x−h+k+−a3x=y+−a3x

−h+k=−a3x+y

Step 3: Add -k to both sides.

−h+k+−k=−a3x+y+−k

−h=−a3x−k+y

Step 4: Divide both sides by -1.

−h

−1

=

−a3x−k+y

h=a3x+k−y

Answer:

h=a3x+k−y

Let's solve for k.

y=a3x−h+k

Step 1: Flip the equation.

a3x−h+k=y

Step 2: Add -a^3x to both sides.

a3x−h+k+−a3x=y+−a3x

−h+k=−a3x+y

Step 3: Add h to both sides.

−h+k+h=−a3x+y+h

k=−a^3x+h+y

Answer:

k=−a^3x+h+y

Step-by-step explanation:

The required values are h = 1 and k = 4 the given cube root function.

The cube root function is a function that takes the cube root of its input. The formula for the cube root function is:

f(x) = ∛x

The graph is given in the question, as shown.

To find the symmetric center of the cube root function, we need to find the point on the function that is equidistant from the two opposite sides of the function graph.

Since the given cube root function is an odd function, it is symmetric about the point (1, 4).

So, the symmetric center of the cube root function is the point (1, 4).

Thus, h = 1 and k = 4

Therefore, the required values are h = 1 and k = 4 the given cube root function.
