I think c=a-7

Step-by-step explanation:

You would the equation a=b+9 to b=a-9. Then you would add 2 to -9 to get -7. So c=a-7.

Answer:

m∠MON = 24°

Step-by-step explanation:

m∠LOM and m∠MON add up to 90°.

Step 1: Find x

2x + 46 + 3x - 6 = 90

5x + 40 = 90

5x = 50

x = 10

Step 2: Find m∠MON

m∠MON = 3x - 6

m∠MON = 3(10) - 6

m∠MON = 30 - 6

m∠MON = 24°

Answer:

Step-by-step explanation:

The area of a triangle of base 8 in, and height 7 in, is

A = (1/2)(base)(height) = (1/2)(8 in)(7 in) = 28 in^2.  This matches the given 28th in^2.

Yes, considering the points, each input gives one output. Points would not be a function if the same input gave different outputs.

In the context of a graph, the points would be on the same vertical line.

Answer:

8 movies and 6 video games

Step-by-step explanation:

Given

[tex]Gift\ Card = \$600[/tex]

[tex]Movies =\ $20[/tex]

[tex]Video\ Game = \$50[/tex]

[tex]Minimum\ Items = 13[/tex]

Required

Determine the items Lonnie can afford

To solve this question, we make use of trial by error method by taking the options one at a time:

Option 1: 6 movies and 4 video games

This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.

Option 2: 14 movies and 7 video games

[tex]Cost = 14 * \$20 + 7 * \$50[/tex]

[tex]Cost = \$280 + \$350[/tex]

[tex]Cost = \$630[/tex]

This option can not be considered because the cost of purchase is greater than Lonnte's worth of Gift card.

Option 3: 2 movies and 10 video games

This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.

Option 4: 8 movies and 6 video games

[tex]Cost = 8 * \$20 + 6 * \$50[/tex]

[tex]Cost = \$160 + \$300[/tex]

[tex]Cost = \$460[/tex]

Hence, the correct option is 8 movies and 6 video games

Answer:

1 is c

2 is d

3 is a

Step-by-step explanation:

because 9×9 is 81

2 is 10 with 3 0 so 10000

d is a because that is the factor tree

The square of the number 9 is 81.

We need to find the value of 9 squared.

When an integer is multiplied by itself, the resultant number is known as its square number. Basically, a square number is a number that is obtained by the product of two same numbers.

Now, the square of 9 is 9²=9×9=81

Therefore, the square of the number 9 is 81.

Simplify 10³:

That is, 10³=10×10×10=1000

So, the simplified form of 10³ is 1000.

We need to prime factorise 96:

That is, 96=2×2×2×2×2×3

=[tex]2^{5} . 3[/tex]

Therefore, the square of the number 9 is 81.

5 nights

The family have to stay 5 nights in order  to cost the same amount of money.

Let us consider that family is staying for x night.

Given that, Option A costs $479 per night and includes airfare in the cost.

So that,         [tex]A(x)=479x[/tex]

Also Option B costs $129 per night but will cost your family $1750 in airfare.

Answer:

1992.38

Step-by-step explanation:

The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.

Sum:

1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56

Divide:

There are 12 numbers, so divide 23908.56 by 12:

23908.56 / 12 = 1992.38

The average is thus 1992.38.

Answer:

The 95 percent confidence interval for the mean of the population from which the study subjects may be presumed to have been drawn is (19.1269, 32.6730).

Step-by-step explanation:

Intern            No. of Breast

Number        Exams Performed               X²

                                  ∑ 259                  ∑ 7515

Mean= X`= ∑x/n= 259/10= 25.9

Variance = s²= 1/n-1[∑X²- (∑x)²/n]

= 1/0[7515- (259)²/10]= 1/9[7515- 6708.1]

= 806.9/9=89.655= 89.66

Standard Deviation= √89.655= 9.4687

Hence

The value of t with significance level alpha= 0.05 and 9 degrees of freedom  is t(0.025,9)= 2.262

The 95 % Confidence interval is given by

x`±t(∝,n-1) s/√n

So Putting the values

25.9± 2.262( 9.4687/√10)

= 25.9 ±2.262 (2.9943)

= 25.9 ± 6.7730

= 25.9 +6.7730=32.6730

25.9 -6.7730= 19.1269

= 19.1269, 32.6730

The 95 percent confidence interval for the mean of the population from which the study subjects may be presumed to have been drawn is (19.1269, 32.6730).

From the question the figure above is a triangle.

The sum of angles in a triangle add up to 180°

To find the value of x add up all the angles and equate them to 180 to find the value of x

We have

50 + 2x + 3x - 10 = 180

5x + 40 = 180

5x = 180 - 40

5x = 140

Divide both sides by 5

Answer:

[tex]S=\{\forall \,s,t\in \mathbb{R}|s\in(-\infty,+\infty), t\in(-\infty,+\infty)\}[/tex]

Step-by-step explanation:

Let be [tex]f(s,t) = \sqrt{s^{2}+t^{2}}[/tex], the range of a square root compehends the subset of positive real numbers plus zero. Likewise, the range of the square of any number has the same subset with all real set as domain. As square root encloses a sum of squares, the domain of the function is:

[tex]S=\{\forall \,s,t\in \mathbb{R}|s\in(-\infty,+\infty), t\in(-\infty,+\infty)\}[/tex]

Subtract the functions to get that answer

(f - g)(x) = f(x) - g(x)

(f - g)(x) = [ f(x)  ] - [ g(x) ]

(f - g)(x) = [ 3^x + 10x  ] - [ 5x - 3 ]

(f - g)(x) = 3^x + 10x - 5x + 3

(f - g)(x) = 3^x + 5x + 3

18 I guess

Step-by-step explanation:

because we are subtracting all the number by 8

To find the common difference since all the values go done, we can subtract each value.

57 - 49 = 8

49 - 41 =  8

41 - 33 = 8

33 - 25 = 8

The common difference is 8 so to find the next number, all we need to do is subtract the last number by 8.

25 - 8 = 17

Therefore, the answer is 17

Answer:

P(n)= p0 + 11(n)

Where p0= population of week 0

P(n) = population of n weeks

n= number of weeks

Step-by-step explanation:

Population of beetles in Week 0= 6

Population of beetles in Week 7= 83

From week 0 to week 7 there are 8 weeks.

But subtracting population of week 0 from population of week 7 gives

= 83-6

= 77

After the subtraction, we have 7 weeks remaining.

Dividing the remaining population by the number of weeks remaining

=77/7

= 11

For n number of weeks, population p of beetles

P(n)= p0 + 11(n)

Where p0= population of week 0

P(n) = population of n weeks

n= number of weeks
