Answer:

[tex]\tan (30 + 60) = unde f ined[/tex]

Step-by-step explanation:

Given

[tex]\tan (A + B) = \frac{\tan A + \tan B}{1 - \tan A * \tan B}[/tex] ---- right expression

[tex]A = 30^o; B = 60^o[/tex]

Required

Solve

[tex]\tan (A + B) = \frac{\tan A + \tan B}{1 - \tan A * \tan B}[/tex]

Substitute: [tex]A = 30^o; B = 60^o[/tex]

[tex]\tan (30 + 60) = \frac{\tan 30 + \tan 60}{1 - \tan 30 * \tan 60}[/tex]

In radical forms, we have:

[tex]\tan (30 + 60) = \frac{\sqrt 3/3 + \sqrt 3}{1 - \sqrt 3/3 * \sqrt 3}[/tex]

[tex]\tan (30 + 60) = \frac{\sqrt 3/3 + \sqrt 3}{1 - 1}[/tex]

[tex]\tan (30 + 60) = \frac{\sqrt 3/3 + \sqrt 3}{0}[/tex]

[tex]\tan (30 + 60) = unde f ined[/tex]

Answer and Step-by-step explanation:

5,000,000 + 600,000 is the expanded form of the number 5,600,000.

Sir there seems to be a picture in your pixels.

i would assume the measurements (from left to right) is 34m 14m 20m and 14m

find the area of the triangle so split the 24 in half 12 and 12

then multiply 12*14 which is 168

i would assume the area is 168m^2

then multiply by 20m

[tex]\bar{x}=650\\\\\sigma =24\\\\n=36\\\\[/tex]

Calculating the sampling distribution of the sample mean:

[tex]\to \mu=\mu_\bar{x}=650[/tex]

Calculating the sampling distribution of the standard deviation:

[tex]\to \sigma_\bar{x}=\frac{\sigma}{\sqrt{n}}=\frac{24}{\sqrt{36}}=\frac{24}{6}=4[/tex]

Anna is 18. Rita is 13.

13

Mark is 12.

Step-by-step explanation:

Recall that the perimeter of a shape is the sum (or total) of all the edges that make up that shape. So, for the first shape, there are three Xs. We write this as [tex]\bold{3x}[/tex] so this is the perimeter.

In the second, there are four Xs, so this is [tex]\bold{4x}[/tex].

In the third, there are two Xs and two 5s, so this is [tex]2x+(2*5)=\bold{10+2x}[/tex].

In the fourth, there are two Xs and three 4s, so this is [tex]2x+(3*4)=\bold{12+2x}[/tex].

If each is equal to 24, we can simply set them as equal to 24 and solve.

[tex]3x = 24\\\bold{x=8}[/tex]

----

[tex]4x=24\\ \bold{x=6}[/tex]

----

[tex]10+2x=24\\2x = 14\\\bold{x=7}[/tex]

----

[tex]12+2x=24\\2x=12\\\bold{x=6}[/tex]

If Anna is 5 years older than Rita, then [tex]a=r+5[/tex]. If their sum is 31, then [tex]a+r=31[/tex]. We can perform some substitution:

[tex](r+5)+r=31\\5+2r=31\\2r=26\\r=13[/tex]

Therefore, Rita is 13. Keep going:

[tex]a=r+5\\a=13+5\\a=18[/tex]

Anna is 18.

If Dad is three times as old as Mark, then [tex]d=3m[/tex]. If the sum of their ages is 48, then [tex]d+m=48[/tex]. We can perform some algebra:

[tex]d+m=48\\m=48-d\\d=3(48-d)\\d=144-3d\\4d=144\\d=36[/tex]

Dad is 36. Keep going:

[tex]d=3m\\36=3m\\m=12[/tex]

Mark is 12.

Answer:

0.3257

Step-by-step explanation:

Given an approximately normal distribution:

Z = (x - mean) / standard deviation

Mean = 496 ; Standard deviation = 110

For :

P(x > 545.7)

We obtain the standardized, Z score

Z = (545.7 - 496) / 110

Z = 49.7 / 110

Z = 0.4518

Hence, using the Z distribution table :

P(Z > 0.4518) = 1 - P(Z < 0.4518)

P(Z > 0.4518) = 1 - 0.67429

P(Z > 0.4518) = 0.32571

Answer:

sqrt. 244

Step-by-step explanation:

a^2 + b^2 =c^2

10^2 + 12^2 =244

c^2 =244

c= sqrt. 244

Answer:

if x+y equal 90

and z equal 2 sqrt 61

if you want the real values of the x and y iam not sure but you have to use ratios and proportions Formula for example 24k=90

k =15/4

y=10k

x=12k

Answer:

Shreya must put in 3 more cups of sugar.

Step-by-step explanation:

Given that a recipe for cupcakes calls for 6 cups of sugar, and Shreya has already put in 3 cups, to determine how many more cups does she need to put in to complete the amount required by the recipe, the following calculation must be performed:

6 - 3 = X

3 = X

Therefore, Shreya must put in 3 more cups of sugar.

Given

A

Find the inverse of f(x):

B

C

Answer: B

Step-by-step explanation:

First, simplify the main expression. The answer is 21.

Then simplify A. It is -106. That is not equal to 21 so A is wrong.

Then simplify B. That is 21. That means B is correct and you don’t have to solve C or D.

Answer:

B) 68.91 inches

Step-by-step explanation:

To start, lets define what we are trying to find. VYX is the major arc VX, spanning from V to X crossing over Y.

We are also given that the diameter is 28 inches.

Since arc length and area are proportional to the central angle, we can create the following equality:

angle of VYX/360 = arc length of VYX/circumference

We know that the central angle of VYX = central angle of minor UV + UYX = 117 + (180-15) = 282 degrees.

282/360 * 28*pi = arc length of VYX

Thus, the length of VYX = 68.90559887 inches

Thus, the correct answer is B, 68.91 in.

Answer:

99.7% confidence interval is [tex][0.4162,0.7437][/tex]

Step-by-step explanation:

The formula for a confidence interval for a population proportion is [tex]CI=\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }[/tex] where [tex]\hat{p}[/tex] is the sample proportion, [tex]n[/tex] is the sample size, and [tex]z^*[/tex] is the critical score for the desired confidence level.

We are given a sample size of [tex]n=80[/tex] and a sample proportion of [tex]\hat{p}=0.58[/tex]. Our critical score for a 99.7% confidence level would be [tex]z^*=normalcdf(0.9985,0,1)=2.9677[/tex]

Therefore, the approximate 99.7% confidence interval for the population parameter is [tex]CI=\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }=0.58\pm 2.9677\sqrt{\frac{0.58(1-0.58)}{80} }=[0.4162,0.7438][/tex]

So we are 99.7% confident that the true population proportion is contained within the interval [tex][0.4162,0.7437][/tex]

Answer:

[tex]\=x=2.1[/tex]

[tex]\sigma=2.03[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size[tex]n=100[/tex]

Probability of  a defective widget [tex]P=0.021[/tex]

Generally the equation for binomial trial is mathematically given by

 [tex]q=1-p[/tex]

 [tex]q=1-0.021[/tex]

 [tex]q=0.979[/tex]

Since X is binomial random variable with functions of n and p,The equation of mean \=x

 [tex]\=x=E(x)[/tex]

  Where

  [tex]E(x=n*p)[/tex]

 [tex]\=x=100*0.021[/tex]

 [tex]\=x=2.1[/tex]

Generally the equation for variance \sigma is mathematically given by

 [tex]\sigma=\sqrt{nqp}[/tex]

 [tex]\sigma=\sqrt{200*0.021*0.979}[/tex]

 [tex]\sigma=2.03[/tex]

Answer:

Rounded to the nearest dollar, Robert will have $ 505 more than Cooper on his account.

Step-by-step explanation:

Given that Cooper invested $ 3,100 in an account paying an interest rate of 2% compounded quarterly, while Robert invested $ 3,100 in an account paying an interest rate of 3% compounded continuously, to determine, after 12 years, how much more money would Robert have in his account than Cooper to the nearest dollar, the following calculation must be made:

Compound interest formula: Initial x (1 + interest / composition) ^ composition x years

Continuous compound interest formula: Initial x exp ^ (interest x years)

Cooper:

3,100 x (1 + 0.02 / 4) ^ 12x4 = X

3,100 x (1 + 0.005) ^ 48 = X

3,100 x 1,005 ^ 48 = X

3,100 x 1,270 = X

3,938.51 = X

Robert:

3,100 x 2.71828182845904 ^ (3x12) = X

4,443.32 = X

4,443.32 - 3,938.51 = X

504.51 = X

Therefore, rounded to the nearest dollar, Robert will have $ 505 more than Cooper on his account.
