The interval of decreasing refers to the interval of x-values where the graph is decreasing or going down.

If we look at the graph:

We can see that the graph starts to decrease or "go down" at values x = -1 and x=0. With this, we can conclude that the interval of decrease for the given graph is (-1, 0)

The probability of the sample mean is 0.2008.

What is probability?
Probability is the quality or state of being probable the extent to which something is likely to happen or be the case.

Sol-Let x be a continuous random variable that has a normal distribution with
μ=48 and σ=8
Thus,
X~N(48,8^2/16)
The standardized value of x is obtained by :
Z= X-48/√8^2/16~N(0,1)

The probability that the sample mean x for a random sample of 16 taken from this population will be between 49.62 and 52.80 can be obtained as:

P(49.62<x<52.80)

P=(49.62-48/√8^2/16<x-48/√8^2/16<52.80-48/√8^2/16)

=P(0.81<Z<2.4)

=P(Z<2.4)-P(Z<0.81)

=0.9918-0.7910

=0.2008
There for the probability is 0.2008.

There would be 20 guests for the restaurants to cost the same

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

From the question, we have the following parameters:

Red Lobster

Rate per person = $30

Set up fee = $100

Olive Garden

Rate per person = $25

Set up fee = $200

So, the equations of the restaurants are

Red Lobster = 30g + 100

Olive Garden = 25g + 200

Where the number of guests is g

When the restaurants cost the same amount, we have

Red Lobster = Olive Garden

Substitute the known values in the above equation

So, we have

30g + 100 = 25g +200

Evaluate the like terms

5g = 100

Divide by 5

g = 20

Hence, the number of guests is 20

After 6 years, Zandile earns an interest of rupees 608.9 after investing her Christmas bonus for R 875.00 in a bank that offers interest rates of 9% p.a. compounded half-yearly.

The simplest way to calculate interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a friend with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5.

Compound interest is when an amount receives interest on top of it each time interest is paid on the original amount. The principal (original) sum and the interest that has already accrued over the course of previous periods are used to calculate compound interest.

Here,

Principal amount= 875

Rate of interest= 9% pa

Compounding= half-yearly (2/year)

Time= 6 years

A = P(1 + r/n)ⁿᵇ

A=final amount

P=initial principal balance

r=interest rate

n=number of times interest applied per time period

b=number of time periods elapsed

A=875(1+9/6)⁶*²

A=₹1,483.90

The rule for a reflection across the x-axis is:

Knowing it, let's write some points that the red line passes through:

(-2, 0) and (0, 4).

Now, let's use this rule and change the sign of the y coordinate:

• (-2, 0) → (-2, 0) because +0 or -0 doesn't exist.

• (0, 4) → (0, -4)

Let's analyze it and find a line that passes through these two points:

(-2, 0) and (0, -4)

It will be the blue line.

Answer:

• x-intercept: (-1.5, 0).

A quadratic equation is one with a single degree 2-variable and has the general form  [tex]a x^{2} + bx + c = 0.[/tex]  a, b, and c is the constant value, and x consists of a variable.

The quadratic equation's x-intercepts are (-5, 0). That indicated that the quadratic equation's two elements are (x + 5) and (x -0).

f(x) = a (x + 5) (x - 0) (x - 0)

= ax+5a

f(x) = [tex]ax^{2} +5x[/tex]

The quadratic equation's graph goes through (4, 0). Therefore, we must change equation 1 to read x = 4 and f(x) = 0.

0 = a × 4² + (5 × 4)

0 = a × 16 +20

a = [tex]\frac{-20}{16}[/tex]

The quadratic equation is known to have the form ax² + bx + c = 0.

f(x) = -1.25[tex]x^{2}[/tex] + 5x

What is distributive property ?

Distributive property states that the outcomes are the same whether the numbers in parenthesis are added before or after multiplication.

We know that according to the distributive property both sides must be equal such that the outcomes are same whether the numbers in parenthesis are added before or after multiplication. The expression for distributive property is given as : a(b + c) = ab + ac

So , checking the options one by one :

A) 36 + 9 = 45 ; is not an equation representing distributive property as it doesn't satisfy the criteria of a distributive property.

B) 36 + 9 = 3(12 + 3) is an equation representing distributive property as it satisfies the criteria mentioned above i.e.,

36 + 9 = 3 × 12 + 3 × 3

36 + 9 = 36 + 9

45 = 45

C) 36 x 9 = 9 x 36 is not an equation representing distributive property.

D)  (12 + 3) × 3 = 3 × (12 + 3) is not an equation representing distributive property because both sides are written in the same way.

If an oil-well contracted drills a shaft 7 meters deeper into the ground every 2 hours, then Graph H  best represents this rate.

The graphs are attached

Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours,

hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour

Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per hour

The slope (rate of change) of a line (m) is given by:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:

Slope of the line , [tex]m = \frac{-20 - 0}{10 - 0}[/tex]

Slope of the line is - 2 meters per hour

b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:

Slope of the line, [tex]m = \frac{-70 - 0}{10 - 0}[/tex]

Slope of the line is -7 meters per hour

c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:

Slope of the line, [tex]m = \frac{-35 - 0}{10 - 0}[/tex]

Slope of the line is -3.5 meters per hour

d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:

Slope of the line, [tex]m = \frac{-3.5 - 3.5}{10 - 0}[/tex]

Slope of the line is 0 meters per hour.

Therefore, if an oil-well contracted drills a shaft 7 meters deeper into the ground every 2 hours, then Graph H  best represents this rate.
