interior angle (3)= 60

Step-by-step explanation:

Given:

exterior angle=120°

interior angle (1)=50°

Required:

interior angle (2)=?

interior angle (3)=?

Formula:

exterior angle=interior angle (1) + interior angle (2)

Solution:

exterior angle=interior angle (1)+ interior angle (2)

120°=50°+interior angle (2)

120°+50°=interior angle (2)

70°=interior angle (2)

interior angle (3)= 180°-interior angle (1)- interior angle (2)

interior angle (3)=180°-50°+70°

interior angle (3)=180°-120°

interior angle (3)= 60°

Answer:

(a) 27 degrees (nearest degree)

(b) 17.9 m  (to one decimal place)

Step-by-step explanation:

Wow, that's along ladder, perhaps for the firemen!

From diagram,

(a)

sin(x) = 9 / 20 = 0.45

x = arcsin(0.45) = 26.74 degrees

(b)

height of wall ladder reaches

h = 20*cos(x) = 20*cos(26.74) = 17.86 m

Answer:

First, a absolute value function is something like:

y = f(x) = IxI

remember how this work:

if x ≥ 0, IxI = x

if x ≤ 0, IxI = -x

Notice that I0I = 0.

And the range of this function is all the possible values of y.

For example for the parent function IxI, the range will be all the positive reals and the zero.

First, if A is the value of the vertex of the absolute function, then we know that A is the maximum or the minimum value of the function.

Now, if the arms of the graph open up, then we know that A is the minimum of the function, and the range will be:

y ≥ A

Or all the real values equal to or larger than A.

if the arms of the graph open downwards, then A is the maximum of the function, and we have that the range is:

y ≤ A

Or "All the real values equal to or smaller than A"

Answer:

Question (2). Option (D)

Question (3). (a). 56

                     (b). 84

Step-by-step explanation:

Question (2).

Since, a% of b = [tex]\frac{a}{100}\times b[/tex]

42% of 350 = [tex]\frac{42}{100}\times 350[/tex]

Therefore, Option (d) is the correct option.

Question (3).

Total number of people who attended the music concert = 700

a). Percentage of people who arrived late in the concert = 8%

Therefore, number of people who attended the concert = 8% of 700

= [tex]\frac{8}{100}\times 700[/tex]

= 56

b). Percentage of people who bought the shirt = 12%

Number of people who bought the shirt = 12% of 700

= [tex]\frac{12}{100}\times 700[/tex]

= 84

Answer:

-5/48

Step-by-step explanation:

(8 · 2⁷ˣ)⁴ = (1/16)⁵ˣ · 128

Take log of both sides.

log (8 · 2⁷ˣ)⁴ = log ((1/16)⁵ˣ · 128)

Use log exponent/product rules.

4 log (8 · 2⁷ˣ) = log (1/16)⁵ˣ + log 128

Use log exponent/product rules.

4 (log 8 + log (2⁷ˣ)) = 5x log (1/16) + log 128

Use log exponent rule.

4 (log 8 + 7x log 2) = 5x log (1/16) + log 128

Distribute.

4 log 8 + 28x log 2 = 5x log (1/16) + log 128

Write as powers of 2.

4 log 2³ + 28x log 2 = 5x log (2⁻⁴) + log 2⁷

Use log exponent rule.

12 log 2 + 28x log 2 = -20x log 2 + 7 log 2

Combine like terms.

5 log 2 + 48x log 2 = 0

Divide by log 2.

5 + 48x = 0

Solve for x.

x = -5/48

When government revenues exceed government outlays in a particular year, this is called a d) budget surplus.

A budget surplus occurs when a government's income from taxes and other sources of revenue exceed its expenses and spending on public programs, services, and infrastructure. A budget surplus is a positive indicator for the government's financial health as it indicates that the government is able to manage its finances well, generate more revenue than it spends, and potentially pay off any debts.

Here, we have,

In contrast, a budget deficit occurs when government spending exceeds its revenue, resulting in increased debt and a potentially negative impact on the government's credit rating.

Budget surpluses can be used to invest in public projects or programs, reduce debt, or returned to taxpayers in the form of tax cuts.

However, it is important to note that budget surpluses can also be a result of reduced spending on public programs, which can have a negative impact on social services and infrastructure.

Therefore, the correct answer is d) budget surplus.

Answer:

The value of  annuity is  [tex]P_v = \$ 7929.9[/tex]

Step-by-step explanation:

From the question we are told that

    The periodic payment is  [tex]P = \$ 250[/tex]

     The  interest rate  is   [tex]r = 5\% = 0.05[/tex]

     Frequency at which it occurs in a year is  n = 4 (quarterly )

      The number of years is  [tex]t = 10 \ years[/tex]

The  value of the annuity is mathematically represented as

             [tex]P_v = P * [1 - (1 + \frac{r}{n} )^{-t * n} ] * [\frac{(1 + \frac{r}{n} )}{ \frac{r}{n} } ][/tex] (reference EDUCBA website)

 substituting values

             [tex]P_v = 250 * [1 - (1 + \frac{0.05}{4} )^{-10 * 4} ] * [\frac{(1 + \frac{0.05}{4} )}{ \frac{0.08}{4} } ][/tex]

             [tex]P_v = 250 * [1 - (1.0125 )^{-40} ] * [\frac{(1.0125 )}{0.0125} ][/tex]

             [tex]P_v = 250 * [0.3916 ] * [\frac{(1.0125)}{0.0125} ][/tex]

Answer : The proportion of the baseballs in the sampled population that are too lively

P = x / n = 18 / 40 = 0.450

Step-by-step explanation:

coefficient of restitution > 0.625

Based on available data the proportion of the baseballs that is in the sampled population that are too lively can be calculated using the values below

n = 40

x = n ( p > 0.625 ) = 18

The proportion of the baseballs in the sampled population that are too lively

P = x / n = 18 / 40 = 0.450

Answer:

E[x] is larger

Step-by-step explanation:

I think E[x] is larger because the expected number of students on the bus of a randomly chosen student is larger.

This is because the higher the number of students present in a bus, the higher the probability that a randomly selected student would have been on that bus.

Whereas, for every driver to be chosen, the probability of any bus being chosen is 1/4 irrespective of the number of students in that particular bus

Answer:

Step-by-step explanation:

[tex]\dfrac{4}{x}+\dfrac{4}{x^2-9}=\dfrac{3}{x-3}[/tex]

Domain:

[tex]x\neq0\ \wedge\ x^2-9\neq0\ \wedge\ x-3\neq0\\\\x\neq0\ \wedge\ x\neq\pm3[/tex]

solution:

[tex]\dfrac{4}{x}+\dfrac{4}{x^2-3^2}=\dfrac{3}{x-3}[/tex]

use (a - b)(a + b) = a² - b²

[tex]\dfrac{4}{x}+\dfrac{4}{(x-3)(x+3)}=\dfrac{3}{x-3}[/tex]

multiply both sides by (x - 3) ≠ 0

[tex]\dfrac{4(x-3)}{x}+\dfrac{4(x-3)}{(x-3)(x+3)}=\dfrac{3(x-3)}{x-3}[/tex]

cancel (x - 3)

[tex]\dfrac{4(x-3)}{x}+\dfrac{4}{x+3}=3[/tex]

subtract [tex]\frac{4(x-3)}{x}[/tex] from both sides

[tex]\dfrac{4}{x+3}=3-\dfrac{4(x-3)}{x}\\\\\dfrac{4}{x+3}=\dfrac{3x}{x}-\dfrac{(4)(x)+(4)(-3)}{x}\\\\\dfrac{4}{x+3}=\dfrac{3x-\bigg(4x-12\bigg)}{x}\\\\\dfrac{4}{x+3}=\dfrac{3x-4x-(-12)}{x}\\\\\dfrac{4}{x+3}=\dfrac{-x+12}{x}[/tex]

cross multiply

[tex](4)(x)=(x+3)(-x+12)[/tex]

use FOIL

[tex]4x=(x)(-x)+(x)(12)+(3)(-x)+(3)(12)\\\\4x=-x^2+12x-3x+36[/tex]

subtract 4x from both sides

[tex]0=-x^2+12x-3x+36-4x[/tex]

combine like terms

[tex]0=-x^2+(12x-3x-4x)+36\\\\0=-x^2+5x+36[/tex]

change the signs

[tex]x^2-5x-36=0\\\\x^2-9x+4x-36=0\\\\x(x-9)+4(x-9)=0\\\\(x-9)(x+4)=0[/tex]

The product is 0 if one of the factors is 0. Therefore:

[tex]x-9=0\ \vee\ x+4=0[/tex]

[tex]x-9=0[/tex]            add 9 to both sides

[tex]x=9\in D[/tex]

[tex]x+4=0[/tex]          subtract 4 from both sides

[tex]x=-4\in D[/tex]

Answer:

A.y = −8x + 80B

Step-by-step explanation:

first you have to find the slope :

P1(2,64). P2(6,32)

slope=Y2-Y1/X2-X1

slope=64-32/2-6

slope= -8

y= -8x + b. now solve for "b" by using one of the coordinates given above.

y= -8x + b. I will use coordinate p(2,64)

64= -8(2) + b

64 + 16 = b

80= b

you can use any of the coordinates i.e either P1(2,64)or P2(6,32) it doesn't affect the value of "b".

line of equation is :

.y = −8x + 80B

Answer: y= -8x+80

Step-by-step explanation:

Answer:

1). f(x) = x² if ∞ < x < 2

2). f(x) = 5 if 2 ≤ x < 4

Step-by-step explanation:

The graph attached shows the function in two pieces.

1). Parabola

2). A straight line parallel to the x-axis.

Standard equation of a parabola is,

y = a(x - h)² + k

where (h, k) is the vertex.

Vertex of the given parabola is (0, 0).

Equation of the parabola will be,

y = a(x - 0)² + 0

Therefore, the function will be,

f(x) = ax²

Given parabola is passing through (-1, 1) also,

1 = a(-1)²

a = 1

Therefore, parabolic function will be represented by,

f(x) = x² if ∞ < x < 2

2). Straight line parallel to the x-axis,

y = 5  if 2 ≤ x < 4

Function representing the straight line will be,

f(x) = 5 if 2 ≤ x < 4

Step-by-step explanation:

Answer:

(-4) will be the smallest value.

Step-by-step explanation:

Two functions have been given in this question,

f(x) = [tex]\sqrt{6x}[/tex] and g(x) = x + 4

Then the composite function (fog)(x) will be,

(fog)(x) = f[g(x)]

f[g(x)] = [tex]\sqrt{6(x+4)}[/tex]

Since this function is defined for (x + 4) ≥ 0

(x + 4) - 4 ≥ 0 - 4

x ≥ -4

Domain of this function : [-4 ∞)

Therefore, the smallest number in the domain or smallest value for 'x' should be (-4).

Answer:

Step-by-step explanation:

The sample of cereal is :

n = 32, Standard deviation = 0.81

The confidence interval is 95%

degrees of freedom = df = 31 (n - 1)

[tex]\alpha[/tex] = 95%

1 - 0.95 = 0.05

1 - [tex]\frac{ \alpha }{2}[/tex]

1 - 0.025 = 0.975

Using chi square distribution we get,

Answer: $951,064.06 would be your answer.

Step-by-step explanation: Hope that helped!

Answer:

Step 1:

To find ordered pair solutions, you could create an x and y graph and fill out the x side. Then, plug in an x number to get your y number and graph the ordered pairs to see if they give you a straight line. I'm going to use these numbers: -1, 0, 1, and 2.

[tex]...x...|...y...[/tex]

[tex]\left[\begin{array}{ccc}-1&?\\0&?\\1&?\\2&?\end{array}\right][/tex]

Now, let's plug in -1 into the equation first to see what we get for y.

[tex]y=8(-1)+3\\y=-8+3\\y=-5\\(-1,-5)[/tex]

-5 is our y if x was -1.

We do the same for the other three numbers.

[tex]y=8(0)+3\\y=0+3\\y=3\\(0,3)[/tex]

[tex]y=8(1)+3\\y=8+3\\y=11\\(1,11)[/tex]

[tex]y=8(2)+3\\y=16+3\\y=19\\(2,19)[/tex]

Step 2:

With all that done, we can now fill out our table and graph the points.

[tex]....x...|...y....[/tex]

[tex]\left[\begin{array}{ccc}-1&-5\\0&3\\1&11\\2&19\end{array}\right][/tex]

If you graph these points on graph paper / a graphing website, you will see that these points go in a straight line. If you are given an ordered pair already (for example: (3,5)), then all you have to do is plug in the x into the equation (3) and see if the outcome is true (5).

[tex]5=8(3)+3\\5=24+3\\5\neq 27[/tex]

Since they don't equal each other, then (3,5) is false.

Here is the graph for the table above. I hope I helped you!

Lets go over the solutions.

Let's start with (1, 11). After substituting x = 1 and y = 11, it results in the equation 11 = 11, which is a true statement. Hence, this is one solution.

Now, let's look at (-1 -5). After substituting x = -1 and y = -5, it results in the equation -5 = -5, which is also a true statement. So, this being said, (-1, -5) would also be a solution.

Hence, our two solutions are:

Both [tex](1, 11)[/tex] and [tex](-1, -5)[/tex].

Hope this helps!

Answer:

a.  0.6588

b. 0.3978

c. 0. 279

Step-by-step explanation:

In the given question the success and failure are given the number of outcomes is fixed so binomial distribution can be applied.

Here success=  p = 12 % or 12/100 = 0.12

failure = q= 1-p = 1-0.12 = 0.88

n= 10

Using binomial probability distribution

a. Probability that the number of selected adults saying they were too young is 0 or 1 is calculated as:

P (x=0,1) = 0.12 ⁰(0.88)¹⁰10 C0  + 0.12 (0.88)⁹ 10 C1=  1* 0.279 * 1  + 0.12 ( 0.3165) 10 =  0. 279 + 0.3978=  0.6588

b. Probability that exactly one of the selected adults says that he or she was too young to get tattoos is calculated as

P (x=1) =  0.12 (0.88)⁹ 10 C1=  0.12 ( 0.3165) 10 =  0.3978

c. Probability that none of the selected adults say that they were too young to get tattoos is

P (x=0) = 0.12 ⁰(0.88)¹⁰10 C0  =  1* 0.279 * 1   =  0. 279

Answer:  see below

Step-by-step explanation:

In order to partition line segment AB so that AP and PB have a ratio of 3 : 1

1) Find the x- and y-lengths of the segment AB.

2) Divide the x- and y-lengths by (3 + 1) to find the length of one section.  

3) Add 3 times those lengths to point A to find point P ...or...

   Subtract 1 times those lengths from point B to find point P.

For example: Consider A = (0, 0) and B = (4, 8)

1) The length from A to B is

   x = 4-0 = 4

   y = 8-0 = 8

2) Divide those by (3 + 1):

   x = 4/4 = 1

   y = 8/4 = 2

3) Add 3 times those values to A to find point P:

   x = 0 + 3(1) = 3

   y = 0+3(2) = 6  

   --> P = (3, 6)

Note: We could have also subtracted 1 from the x-value of B and 2 from the y-value of B to find that point P = (4-1, 8-2) = (3, 6)

Now we know that the distance from point A to point P is 3 times the distance from point P to point B.

H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.

Step-by-step explanation:

We formulate our hypotheses as

H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.

Supposing the probability or proportion of the first survey is equal to the probability or proportion of the second survey. This will be the null hypothesis and the alternative hypotheses would be that these two proportions or probabilities are unequal.

This is a two tailed test.

So we need to distribute 3/4 to (1/2x - 12)

3/8x - 9 + 4/5

3/8x - 9 4/5

Thus,

the answer is 3/8x - 9 4/5.

Answer:

9 years = 12 grams

Step-by-step explanation:

0 years = 96 grams

After 3 years , the amount left is 1/2 of what you started with

3 years = 1/2 *96 = 48 grams

After 3 years , the amount left is 1/2

6 years = 1/2 (48) = 24 grams

After 3 years , the amount left is 1/2

9 years = 1/2 ( 24) = 12 grams

Answer: The population reach 111 million in 2007.

Step-by-step explanation:

In the year 2000, the population of Mexico was about 100 million, and it was growing by 1.53% per year.

At this growth rate, the function [tex]f(x) = 100(1.0153)^x[/tex] gives the population, in millions, x years after 2000.

Put f(x)=111 million.

Then,

[tex]111=100(1.0153)^x\\\\\Rightarrow\ (1.0153)^x=\dfrac{111}{100}=1.11\\\\\Rightarrow (1.0153)^x=1.11[/tex]

Taking log on both the sides , we get

[tex]x\log1.0153=\log1.11\\\\\Rightarrow\ x=\dfrac{\log1.11}{\log1.0153}=\dfrac{0.045323}{0.0066}=6.86712121212\approx7[/tex]

Hence, the population reach 111 million in 2007 (approx).
