Answer:

If we're looking for those that don't have insurance, it's 504. If we're looking for those that do, it's 1,512.

Step-by-step explanation:

Multiply 22.4 by 30 because there's roughly 30 days in a month. You'll get 2,016. Divide 2,016 by 4. You'll get 504. Multiply 504 by 3 to get how many have insurance.

Answer:

Median

Step-by-step explanation:

You want to use median because it is the most accurate when there is an outlier in the data (the 40 on the test)

Answer:

x = 4

Step-by-step explanation:

Distribute 2 to the parentheses:

2(x + 3) = x + 10

2x + 6 = x + 10

Subtract x from both sides:

x + 6 = 10

Subtract 6 from both sides:

x = 4

So, x = 4

Answer: x = 4

Given:

A right triangle with angles 30, 60, 90 degrees.

Hypotenuse = [tex]2\sqrt{2}[/tex] mm.

Base = y

To find:

The value of y.

Solution:

In a right angle triangle,

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos (60^\circ)= \dfrac{y}{2\sqrt{2}}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{2\sqrt{2}}[/tex]

[tex]\dfrac{2\sqrt{2}}{2}=y[/tex]

[tex]\sqrt{2}=y[/tex]

Therefore, the value of y is [tex]\sqrt{2}[/tex] mm.

Given:

The graph of a quadratic function passes through the points (5,31) (3,11) (0,11).

To find:

The equation of the quadratic function.

Solution:

A quadratic function is defined as:

[tex]y=ax^2+bx+c[/tex]            ...(i)

It is passes through the point (0,11). So, substitute [tex]x=0,y=11[/tex] in (i).

[tex]11=a(0)^2+b(0)+c[/tex]

[tex]11=c[/tex]

Putting [tex]c=11[/tex] in (i), we get

[tex]y=ax^2+bx+11[/tex]               ...(ii)

The quadratic function passes through the point (5,31). So, substitute [tex]x=5,y=31[/tex] in (ii).

[tex]31=a(5)^2+b(5)+11[/tex]

[tex]31-11=a(25)+5b[/tex]

[tex]20=25a+5b[/tex]

Divide both sides by 5.

[tex]4=5a+b[/tex]                  ...(iii)

The quadratic function passes through the point (3,11). So, substitute [tex]x=3,y=11[/tex] in (ii).

[tex]11=a(3)^2+b(3)+11[/tex]

[tex]11-11=a(9)+3b[/tex]

[tex]0=9a+3b[/tex]

Divide both sides by 3.

[tex]0=3a+b[/tex]                 ...(iv)

Subtracting (iv) from (iii), we get

[tex]4-0=5a+b-3a-b[/tex]

[tex]4=2a[/tex]

[tex]\dfrac{4}{2}=a[/tex]

[tex]2=a[/tex]

Putting [tex]a=2[/tex] in (iv), we get

[tex]0=3(2)+b[/tex]

[tex]0=6+b[/tex]

[tex]-6=b[/tex]

Putting [tex]a=2,b=-6[/tex] in (ii), we get

[tex]y=(2)x^2+(-6)x+11[/tex]

[tex]y=2x^2-6x+11[/tex]

Therefore, the required quadratic equation is [tex]y=2x^2-6x+11[/tex].

Answer:

It is a one-to-one function

Answer: one to one function

Step-by-step explanation:

M-5/8 = -1/4

Add 5/8 to both sides:

M = -1/4 + 5/8

Rewrite the fractions to have a common denominator

-1/4 = -2/8

Now you have m = -2/8 + 5/8

M = 3/8

Answer:

The answer is 0.375 (3/8)

Step-by-step explanation:

Since the M is subtracted by 5/8, you add 5/8 to both sides of the equation to get the M by itself and -1/4+5/8 equals 0.375, or 3/8

Step-by-step explanation:

Answer: 11

Step-by-step explanation:

Given

The second term of an AP is 7

The sixth term of an AP is 23

Suppose a and d be the first term and common difference of the sequence

[tex]\Rightarrow 7=a+d\quad \ldots(i)\\\Rightarrow 23=a+5d\quad \ldots(ii)[/tex]

Subtract the above equations

[tex]\Rightarrow 23-7=5d-d\\\Rightarrow 16=4d\\\Rightarrow d=4[/tex]

Put d in equation (i)

[tex]\Rightarrow 7=a+4\\\Rightarrow a=3[/tex]

So, the third term of the AP is [tex]a+2d[/tex]

[tex]\Rightarrow 3+2\times 4=11[/tex]

Answer:

Using pythagoras theorem

Answer:

Find answers below.

Step-by-step explanation:

The equation isn't explicitly stated or well written. Thus, we would assume two (2) case scenario for the equation of line by altering the signs.

Scenario 1;

y = 9 + x

Mathematically, the equation of a line is given by the formula;

Equation of straight line is y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Comparing the two equations, we have;

y = mx + c = 9 + x

Constant, c = 9

Slope, m = 1

Scenario 2.

y = 9 - x

y = mx + c = 9 - x

Constant, c = 9

Slope, m = -1

Given ΔRST with:

Solution

We know t is opposite ∠T and r is opposite ∠R.

Use the law of sines to find the missing value of t.

Substitute the known values and solve for t:

Answer:

t = 6

Step-by-step explanation:

In ΔRST:

Sine Rule

[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

Given:

Substitute the given values into the Sine Rule formula and solve for t:

[tex]\implies \sf \dfrac{r}{\sin R}=\dfrac{s}{\sin S}=\dfrac{t}{\sin T}[/tex]

[tex]\implies \sf \dfrac{15}{\sin 30^{\circ}}=\dfrac{t}{\frac{1}{5}}[/tex]

[tex]\implies \sf \dfrac{15}{\sin 30^{\circ}}=5t[/tex]

[tex]\implies \sf t=\dfrac{15}{5 \sin 30^{\circ}}[/tex]

[tex]\implies \sf t=\dfrac{15}{5 \cdot \frac{1}{2}}[/tex]

[tex]\implies \sf t=\dfrac{15}{\frac{5}{2}}[/tex]

[tex]\implies \sf t=15 \cdot \dfrac{2}{5}[/tex]

[tex]\implies \sf t=\dfrac{30}{5}[/tex]

[tex]\implies \sf t=6[/tex]
