Step-by-step explanation:

2.5 miles = 12 fishes

Therefore,

8 miles = 12*8/2.5=96/2.5= 960/25=38.4 fishes

Answer:

120 Phones

Step-by-step explanation:

3/5 of 200

Step 1: Divide 200 by 5

200 ÷ 5 = 40

Step 2: Multiply 40 by 3

40 · 3 = 120

Answer: 3/5 of 200 = 120

Tip: When finding a fraction of a whole, divided the whole by the denominator, then multiply the quotient you got by dividing the whole by the denominator by the numerator

Example: 1/2 of 80

80 ÷ 2 = 40

40 · 1 =40

1/2 of 80 = 40

According to multiplication you can use repeated addition to get the same product of the given equation.

Ex: 5x2= 2+2+2+2+2 ( 5 groups of 2)

Both will give you same answer (10).

The features of the function g(x) = 4log(x) + 4 are

The function is given as;

g(x) = 4log(x) + 4

The intercept

A logarithmic function has no y-intercept.

Set g(x) to 0, to determine the x-intercept

4log(x) + 4 = 0

Divide through by 4

log(x) + 1 = 0

This gives

log(x) = -1

Take the inverse of both sides

x = 10^-1

Evaluate

x = 0.1

The x-intercept is (0.1, 0)

The vertical asymptote

Recall that:

A logarithmic function has no y-intercept.

This is so because it is undefined at x = 0

So, the vertical asymptote is x = 0

The domain and the range

A logarithmic function cannot take a negative input or 0 input

So, the domain is x > 0

However, the range is all set of real numbers i.e (-∞, ∞)

Hence, the features of g(x) are (b), (d) and (e)

The distribution where the mean is most likely to be less than the median is the third histogram.

It should be noted that when the histogram shows the day is left skewed, it means the mean is less than the median.

If it right skewed, the mean is greater than the median.

When they're equal, the data is symmetric.

Answer:

  x = 1, 4

Step-by-step explanation:

We assume the graph is of the relation y = f(x). The desired values of x are those that correspond to points where the y-value is -2.

We are only interested in the x-coordinates of points that lie on the horizontal line where y = -2. Those points are (1, -2) and (4, -2).

The values of x such that f(x) = -2 are x=1 and x=4.

The conditional and its converse that form a true biconditional is; Option A;  If x = 19, then 2x – 3 = 35.

A) If x = 19, then 2x – 3 = 35.

Thus, 2(19) - 3 = 35. Thus, this is a true biconditional.

B) If x = 3, then x²= 9.

This is not a true biconditional because x could also be -3.

C) If x² = 4, then x = 2

This is not a true biconditional because x could also be -2.

D) If x > 0, then |x| > 0.

This is not a true biconditional because x could also be negative which less than zero.

The tenth term of the arithmetic sequence will be 15. Then the correct option is A.

Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as

[tex]\rm a_n = a_1 + (n - 1)d[/tex]

We have

a₇ = 6

d = 3

n = 7

Then the first term will be

a₇ = a₁ + (7 – 1)3

6 = a₁ + 18

a₁ = 6 – 18

a₁ = -12

Then the 10th term will be

a₁ = -12

d = 3

n =10

Then we have

a₁₀ = -12 + (10 – 1)3

a₁₀ = -12 + 27

a₁₀ = 15

Then the tenth term of the arithmetic sequence will be 15.

Then the correct option is A.

Answer:

x = 6

Step-by-step explanation:

Line segment SU is a bisector of angle <TSV which means it divided the angle into two equal parts:

The measure of <TSV = 62 in this case the measure of <VSU = 62/2 = 31

we can write the following equation to find the value of x

5x + 1 = 31 subtract 1 from both sides

5x = 30 divide both sides by 5

Answer: 70%

Step-by-step explanation:

A basket contains:

5 yellow balls

3 blue balls

2 white balls

What would be the probability of randomly picking a ball and the ball not being blue?

So, we can find the probability of picking up a blue ball. Let's do that first.

To calculate the probability of getting a blue ball, we need to divide the number of blue balls by the number of possible balls.

The number of blue balls = 3

The total number of balls = 2 + 3 + 5 = 10 balls

3 blue balls divided by 10 balls = 0.3.

If you multiply 0.3 by 100%, it will give you a probability of finding a blue ball equal to 30%

Now, we just need to find the probability of NOT finding a blue ball. Because we have 30% of finding a blue ball, we just need to subtract 30% from 100%.

100 - 30$ = 70%

The probability of not getting a blue ball is equal to 70%.

To find the area of composite shapes, we can break the bigger shape down into small, simpler shapes, and find the sum of their areas.

For this triangle, we will need to know the formula to find the area of a triangle:

[tex]A=\dfrac{1}{2}bh[/tex]

The given shape can be seen as one large triangle with a little triangle cut out of it. To find the shaded region, we can:

[tex]A=\dfrac{1}{2}bh[/tex]

⇒ Plug in the values given for the base and height:

[tex]A=\dfrac{1}{2}(5)(2+4+6)\\\\A=\dfrac{1}{2}(5)(12)\\\\A=(5)(6)\\\\A=30 mm^2[/tex]

[tex]A=\dfrac{1}{2}bh[/tex]

⇒ Plug in the values given for the base and height:

[tex]A=\dfrac{1}{2}(3)(4)\\\\A=(3)(2)\\\\A=6mm^2[/tex]

[tex]30 mm^2-6mm^2\\=24mm^2[/tex]
