Step-by-step explanation:

Ratios show that Julie earns 50% more than Simon, and John earns 12.5% less than Julie.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Lets divide each salary by 1,000 to express the salaries in thousands of rands:

Simon earns 4,000 / 1,000 = 4,000

Julie earns 6,000 / 1,000 = 6,000

John earns 3,500 / 1,000 = 3,500

Now, we can compare the salaries by expressing them as ratios:

Simon: Julie = 4,000 : 6,000 = 2 : 3

Julie: John = 6,000 : 3,500 = 6 : 3.5

Simon: John = 4,000 : 3,500 = 4 : 3.5

Hence, ratios show that Julie earns 50% more than Simon, and John earns 12.5% less than Julie.

Answer: y = x - 3

Step-by-step explanation:

y-intercept = -3

(0,-3) (4, 1)

m = (x₂ - x₁) / (y₂ - y₁)

m = (4 - 0) / (1 - (-3))

m = 4 / 4

m = 1

y = 1x -3

y = x - 3

To find the value of x for which the function f(x) = -4x^2 + 8x + 10 reaches its global maximum, we need to find its critical points.

First, we find the derivative of the function:

f'(x) = -8x + 8

Next, we set f'(x) = 0 and solve for x:

-8x + 8 = 0

-8x = -8

x = 1

This is the critical point. To determine whether this critical point corresponds to a maximum or a minimum, we look at the second derivative of the function:

f''(x) = -8

Since f''(x) is negative, this critical point corresponds to a maximum.

Therefore, the value of x for which the function f(x) = -4x^2 + 8x + 10 reaches its global maximum is x = 1.

What is sampling distribution ?

An example of a sampling distribution is a probability distribution of a statistic that is derived from repeated sampling of a particular population.            

                         It depicts a spectrum of potential results for a statistic, such as the mean or mode of a variable, for a population.

Given,

Two simulations will be conducted for the sampling distribution of a sample proportion from a population with a true proportion of 0.325.

Simulation A will consist of 1500 trials with a sample size of 100.

Simulation B will consist of 2000 trials with a sample size of 50.

Center for Simulation A and Simulation B will be roughly equal.  

Overall Sample size of Simulation A will be

  = 1500 * 100  = 150000

The company should adopt the new tread pattern, as the test statistic is lower than the critical value.

For this problem, we will use a one-tailed hypothesis test to determine if the company should adopt the new tread pattern. The null hypothesis (H0) is that the tires will not allow a car traveling at 60 mph to come to a complete stop within an average of 125 feet after the brakes are applied. The alternative hypothesis (H1) is that the tires will allow a car traveling at 60 mph to come to a complete stop within an average of 125 feet after the brakes are applied.

The test statistic used here will be the mean of the sample set, which is 125.33 feet. We need to find the critical value to determine whether or not the company should adopt the new tread pattern. To do this, we will use a one-sample t-test with a significance level of 0.05.

After taking into account the outlier (102 feet), the critical value is 1.711. Since the test statistic (125.33) is lower than the critical value (1.711), we can reject the null hypothesis and conclude that the company should adopt the new tread pattern. The outlier was accounted for by performing a one-tailed hypothesis test rather than a two-tailed hypothesis test. This allowed us to look at the data in the context of a single direction (whether or not the tires meet the objective), so that the outlier did not affect the results.

The company should adopt the new tread pattern, as the test statistic is lower than the critical value.

Measure of each missing angles are,

⇒ ∠EFC = 51°

⇒ ∠DFG = 51°

⇒ ∠HEF = 36°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.  

We have to given that;

⇒ m ∠CFG = 129°

⇒ m ∠HFD = 93°

Now, By figure EFG make a linear line.

So, We get;

⇒ ∠EFC + ∠CFG = 180°

⇒ ∠EFC + 129° = 180°

⇒ ∠EFC = 180° - 129°

⇒ ∠EFC = 51°

In the figure, Measure of ∠EFC and ∠DFG are vertically opposite angle.

Hence, Both are equal.

⇒ ∠DFG = ∠EFC = 51°

Here, EFG make a linear line.

Hence, We get;

⇒ ∠HEF + ∠HFD + ∠DFG = 180°

Substitute all the values, we get;

⇒ ∠HEF + 93° + 51° = 180°

⇒ ∠HEF + 144° = 180°

⇒ ∠HEF = 180° - 144°

⇒ ∠HEF = 36°

Thus, Measure of each missing angles are,

⇒ ∠EFC = 51°

⇒ ∠DFG = 51°

⇒ ∠HEF = 36°

The number of revolutions made by larger pulley is,  1032

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

A pulley has a diameter of 8 inches,

And it is belted to a pulley that has a diameter of 12 inches,

the speeds of the pulleys vary inversely to their diameters,

The smaller pulley running at speed of 1,548 revolutions per minute,

The larger pulley running at speed = ?

V α 1/d

Now, it can be written as,

V₁ α  1/d₁

V₂ α 1/d₂

1548 α  1/8

V₂ α 1/12

For removing proportionality sign,

It required to add one constant k,

1548 =  k(1/8)    _____(i)

V₂  = k (1/12)     _____(ii)

Now, by dividing both the equations,

V₂/1548   = k x (1/12)/ k x(1/8)  

V₂/1548 = 8/12

V₂ = 8/12 x 1548

V₂ = 1032

The equation of the line passing through (1, 6) and (3, 2) is y = -2x+8

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, a line passes through (1, 6) and (3, 2), we need to find the equation of the line,  

We know that, an equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by,

(y-y₁) = (y₂-y₁) / (x₂-x₁) (x-x₁)

Here, (x₁, y₁) and (x₂, y₂) = (1, 6) and (3, 2),

Therefore,

(y₂-y₁) / (x₂-x₁) = 2-6 / 3-1 = -4/2 = -2

Setting the equation,

y-6 = -2(x-1)

y-6 = -2x+2
