On average, the high school students' times were lower, so the mean of the high school students' times was lower.

We don't know enough about the actual results to know any more than that.

Answer: d

Answer:

D

Step-by-step explanation:

The tangent- tangent angle x is half the difference of the measures of the intercepted arcs.

The 2 arcs on the circle = 360°, thus

outer arc = 360° - 96° = 264° , then

x = [tex]\frac{1}{2}[/tex]( 264 - 96)° = [tex]\frac{1}{2}[/tex] × 168° = 84°

Answer:

5

Step-by-step explanation:

Because 3 x -2 -6 and -6+6=0 so -2+7 has to be 5

The required value of X + 7 is equal to 5.

An expression is given in the question ; i.e., 3x + 6 = 0

We have to find out the value of the 'X + 7'.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , division , etc.

As per the question ;

The given expression is 3x + 6 = 0

Let's solve it to get the value of x.

i.e.,

3x + 6 = 0

3x = - 6

x = - 2

So ,

The value of X + 7 will be ;

= -2 + 7

= 7 - 2

= 5

Thus , the required value of X + 7 is equal to 5.

Answer:

This is not a function.

Step-by-step explanation:

A function by definition will map one element of the domain to one element of the range.  In this example, we would need one element of A to match one element of B for all elements of A.

Note, there are two elements in set A that map to one element in set B, while one element in set B has no mapping from any element in set A.

Cheers.

Answer:

13

Step-by-step explanation:

Hello, we can write a two digit number 'ab' as 10 * a + b, where a and ba are two integer between 0 and 9.

For instance, 54= 50 + 4 = 5 *10 + 4, a = 5 b = 4, right?

The sum of a two digit number is 4.

a + b = 4

If the order of the digits are reversed, the result is a number that exceeds the original number by 18.

10b + a = 10a + b + 18

9b = 9a + 18

b = a + 2

We can replace in the first equation,

a + a + 2 = 4

2a = 2

a = 1

and then, b = 3

So the number is 13.

thank you

Therefore:

k = 77

Plug it in:

77 ÷ 11 = 7

Answer:

77

Step-by-step explanation:

K ÷ 11 = 7

K = 7 × 11

K = 77

K is 77

[tex]32\frac{2}{3}[/tex]

Step-by-step explanation:

Hello!

To put 32 R2 as a mixed number we put 32 as the whole number and the remainder over the divider which gives us,

[tex]32\frac{2}{3}[/tex]

The answer is [tex]32\frac{2}{3}[/tex]

Hope this helps!

The expression 98 divided by 3 to a mixed number is 32 2/3

From the question, we have the following parameters that can be used in our computation:

Number = 98 divided by 3

Divide 98 by 3

so, we have the following representation

Quotient = 32

Next, we have

Remainder = 98 - 32 * 3

Evaluate the products

Remainder = 2

Hence, the fraction to a mixed number is 32 2/3

Answer:

[tex]2 \frac{59}{72}[/tex]

Step-by-step explanation:

3 3/8 = 3 + 3/8 = 24/8 + 3/8 = 27/8

then:

-5/9 + 3 3/8 = -5/9 + 27/8

= -40/72 + 243/72

= 203/72

203/72 = 144/72 + 59/72 = 2 + 59/72

= 2 59/72

[tex] \boxed{ \bold{ \sf{Price \: of \: the \: article = \: Rs \: 6678.3}}}[/tex]

[tex] \boxed{ \bold{ \sf{Vat \: amount = \: \: Rs \: 768.3}}}[/tex]

Step-by-step explanation:

Given,

Marked Price ( MP ) = Rs 6000

Vat percent = 13 %

Discount percent = 15%

▪️Finding the discount amount

Discount amount = Discount % of MP

= 15 % of 6000

= Rs 900

▪️Finding the selling price

Selling price ( SP )= Marked price - Discount amount

= Rs 6000 - Rs 900

= Rs 5910

▪️Finding the vat amount

Vat amount = Vat % of SP

= 13 % of 5910

= Rs 768.3

▪️Finding SP with VAT

SP with vat = SP + vat amount

= Rs 5910 + Rs 768.3

= Rs 6678.3

Explanation:

The coefficient is the number just to the left of the variable. So that's why -8 is the coefficient for -8x. This is the variable term while 15 is the constant (it has no variable multiplied with it). The two terms are 15 and -8x since we can write 15-8x as 15+(-8x). Terms are separated by a plus sign.

Complete question :

The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.

Dogs(d) - - birds(b)

40 - - - - - - 10

50 - - - - - - 8

Answer:

b = k/d ; 40

Step-by-step explanation:

From the table:

Dogs(d) - - birds(b)

40 - - - - - - 10

50 - - - - - - 8

The number of birds(b) in a park increases when the number of dogs (d) decreases.

Hence we can infer that an inverse relationship exists between them.

Number of birds(b) ∝ 1 / number of birds

b ∝ 1 / d

b = k/d

k = (b × d)

Where k is the proportionality constant

When d = 40, b = 10

Solve for k

k = (40 * 10)

k = 400

Therefore, number of birds(b), when there are 10 dogs;

b = k/d

k = 400, d = 10

b = 400 / 10

b = 40

40 birds when dogs = 10

Answer:

The two consecutive even integers = (4, 6)

Step-by-step explanation:

We are asked in the question to find two consecutive even integers such that 5 times their sum is 26 more than their product.

Two consecutive even integers is represented as: x, x + 2

Five times their sum is 26 more than their products

5( x + x + 2) = [x × (x + 2)] + 26

5( 2x + 2) = (x² + 2x) + 26

10x + 10 = (x² + 2x ) + 26

x² + 2x + 26 - 10x - 10 = 0

x² - 8x + 16 = 0

We factorise

x² - 4x - 4x + 16 = 0

(x² - 4x) -(4x + 16) = 0

x(x - 4) -4(x - 4) = 0

(x - 4)(x - 4) = 0

(x - 4)²

Hence

x - 4 = 0

x = 4

Since, we know that two consecutive even integers = (x , x + 2)

First even integer = x = 4

Second even integer = x + 2 = 4 + 2

= 6

Therefore, the two consecutive even integers = (4, 6)

Answer:

{x | -1 < x ≤ 2}

Step-by-step explanation:

Interval given in the notation of (a, b) denotes,

Upper limit at 'b' and lower limit at 'a'

Sign () denotes the interval between a and b exclusive of the numbers a and b.

Interval given as [a, b] represents,

a = lower limit

b = higher limit

Notation of [] show the interval inclusive of these numbers.

Given set in the question is (-1, 2]

Here (-1) is the lower limit and 2 is the upper limit.

(] notation shows exclusive of (-1) and inclusive of 2.

Therefore, solution set in set-builder notation will be {x | -1 < x ≤ 2}

Answer:

(See explanation below for further details)

Step-by-step explanation:

A second order polynomial (quadratic function) can be well represented with at least three distinct points. Let is take five equidistant different points:

x = 0

[tex]f(0) = 3\cdot (0)^{2}-8\cdot (0) +2[/tex]

[tex]f(0) = 2[/tex]

x = 1

[tex]f(1) = 3\cdot (1)^{2}-8\cdot (1)+2[/tex]

[tex]f(1) = -3[/tex]

x = 2

[tex]f(2) = 3\cdot (2)^{2}-8\cdot (2)+2[/tex]

[tex]f(2) = -2[/tex]

x = 3

[tex]f(3) = 3\cdot (3)^{2}-8\cdot (3)+2[/tex]

[tex]f(3) = 5[/tex]

x = 4

[tex]f(4) = 3\cdot (4)^{2}-8\cdot (4) + 2[/tex]

[tex]f(4) = 18[/tex]

The table of points from the equation [tex]f(x) = 3\cdot x^{2}-8\cdot x +2[/tex] is:

          [tex]x[/tex]                            [tex]f(x)[/tex]

          0                             2
