The required solutions of the functions are given as follows,

1. f(−7) = 35

2. f(−1) =  -1

3. f(0) =  1

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
1 .
for x = -7
f(x) = x² + 2x
f(-7) = (-7)² + 2(-7) = 35

2.
for x = -1
f(x) = x² + 2x
f(−1) = (-1)² + 2(-1) = -1

3.
For x = 0
f(x) = x + 1

f(0) = 0 + 1 =  1

Thus, the required solutions are given as follows,

1. f(−7) = 35

2. f(−1) =  -1

3. f(0) =  1

Answer:

A) The critical value found is 5.99 which is < the test statistic value ( 6.94 ) hence we will reject the null hypothesis (H₀)

The P-value associated is : 0.031 which is < 0.05 ( level of significance )

B) from the calculation it can be sen that employees of small companies are more likely without health insurance

Step-by-step explanation:

A) To conduct a test of independence

we apply the hypothesis test

Null hypothesis (H₀) = The health insurance coverage is independent of the size of the company

Alternative hypothesis (H₁)  = The health insurance coverage is not independent of the size of the company

The test statistic is calculated  as attached below

also the expected values are attached below indicating the formula used

E = expected value

O = observed value

Test statistic value ( as calculated ) = 6.94

The critical value found is 5.99 which is < the test statistic value ( 6.94 ) hence we will reject the null hypothesis (H₀)

The P-value associated is : 0.031 which is < 0.05 ( level of significance )

B) percentage of employees without health insurance

Small company : 14/50 * 100 = 28%

medium company: 10/75 * 100 = 13%

large company : 12/100 * 100 = 12%

from the above calculation it can be sen that employees of small companies are more likely without health insurance

The roots of the given quadratic equation are 5 and -4

Quadratics are the polynomial equation which has the highest degree of 2. Also, called quadratic equations.

Given is an equation 3x²-13x-10 = 0, we need to solve by using completing the square method,

The given equation is =

3x²-13x-10 = 0

3(x²-13x/3-10/3) = 0

3(x²-2x·13x/6-10/3) = 0

Adding and subtracting (13/6)²

3(x²-2x·13x/6+(13/6)²-(13/6)²-10/3) = 0

3[(x-13/6)²-169/36-10/3] = 0

3[(x-13/6)²-289/36] = 0

(x-13/6)²-289/36 = 0

(x-13/6)² = 289/36

Taking roots,

x-13/6 = ±17/6

x = 17/6+13/6

x = 5

Or,

x = -17/6+13/6

x = -4

Hence, the roots of the given quadratic equation are 5 and -4

Step-by-step explanation:

Answer:

BOYS = 30.

GIRLS = 12.

Step-by-step explanation:

Boys: B

Girls: G

B = (2/5)G

B + G = 42.

(2/5)G + G = 42

2G + 5G = 210

7G = 210

G = 210/7

G = 30.

B = (2/5)G

B = (2/5)(30)

B = 60/5

B = 12.

Answer:

\(\Huge \boxed{\bold{\text{12 Boys}}}\)

\(\Huge \boxed{\bold{\text{30 Girls}}}\)

Step-by-step explanation:

Let the number of girls be \(g\) and the number of boys be \(b\).

According to the problem: \(b = \frac{2}{5} \times g\)

We also know that the total number of students is 42, so \(b + g = 42\).

Now, we have two equations with two variables:

We can solve these equations to find the values of \(b\) and \(g\).

Step 1: Solve for \(\bold{b}\) in terms of \(\bold{g}\)

From the first equation, we have\(b = \frac{2}{5} \times g\)

Step 2: Substitute the expression for \(\bold{b}\) into the second equation

Replace \(b\) in the second equation with the expression we found in step 1.

\(\frac{2}{5} \times g + g = 42\)

Step 3: Solve for \(\bold{g}\)

Now, we have an equation with only one variable, \(g\):

\(\frac{2}{5} \times g + g = 42\)

To solve for \(g\), first find a common denominator for the fractions:

\(\frac{2}{5} \times g + \frac{5}{5} \times g = 42\)

Combine the fractions:

\(\frac{7}{5} \times g = 42\)

Now, multiply both sides of the equation by \(\frac{5}{7}\) to isolate \(g\):

Step 4: Find the value of \(\bold{b}\)

Now that we have the value of \(g\), we can find the value of \(b\) using the first equation:

So, there are 12 boys and 30 girls in the class.

Answer:

3576 infected people

Step-by-step explanation:

We have to apply the following formula, which tells us the number of healthy people:

A = p * (1 - r / 100) ^ t

where,

p = initial population,

r = rate of change per period (days)

t = number of periods (days)

Now, we know that the initial population is 3,662 but there are already a total of 36 infected, therefore:

3662 - 36 = 3626

that would be our p, now, we replace:

A = 3626 * (1 - 34/100) ^ 9

A = 86.16

Therefore, those infected would be:

3662 - 86.16 = 3575.84

This means that there are a total of 3576 infected people.

The extremity of the large hand of the clock moves approximately 1.54 inches in 20 minutes.

How does a clock function ?

The large hand of a clock completes a full rotation in 12 hours, or 720 minutes. This means that it moves 360 degrees in 720 minutes, or 0.5 degrees per minute. Since the length of the hand is 28 inches, we can use trigonometry to find out how far its extremity moves for a certain angle.

Calculating the length that  the extremity of the large hand of the clock moves :

The angle that the large hand moves in 20 minutes can be found by multiplying the number of minutes by the rate at which it moves:

angle = \(20 \times 0.5 = 10\) degrees

Using trigonometry, we can find the distance that the extremity of the hand moves by finding the length of the arc of the circle that corresponds to a 10-degree angle, with the radius being 28 inches:

arc length = \((angle/360) \times 2 \times \pi \times 28\)

\(= (10/360) \times 2 \times \pi \times 28\)

\(= 1.54\) inches

Therefore, the extremity of the large hand of the clock moves approximately 1.54 inches in 20 minutes.
