Constant of proportionalityOriginRise over runWhat is a proportional relationship?Proportional relationships are those in which the ratios of two variables are equal. Another way to think about them is that one variable in a proportional relationship is always a constant value multiplied by the other. This is known as the "constant of proportionality."
The proportionality constant is the ratio that connects two given values in a proportional relationship. The constant of proportionality is also known as the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.
The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope formula is the rise over run formula, where the fraction consists of a rise, whether the line is going up or down, divided by the run.

The theorem that proves that the triangles are congruent is the Hypotenuse-leg (HL) Congruence Theorem. The correct option is the first option - HL Congruence Theorem
Congruent triangles: Hypotenuse-leg theorem (HL)From the question, we are to determine by what theorem of postulate the triangles can be proven congruent.
From the Hypotenuse-leg theorem which states that "if the hypotenuse and a leg of a right triangle are each congruent with the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent".
From the given diagram, we can observe that the hypotenuse of the first triangle is congruent to the hypotenuse of the second triangle. Likewise, we can observe that one of the legs of the first triangle is congruent to the one of the legs of the other triangle.
Hence, the triangles are congruent by the Hypotenuse-leg theorem.

What is the double-declining-balance method?The double-declining-balance method is one of the depreciation methods in use, but it allocates more cost to the earlier years of the asset's life.
This depreciation method uses twice the straight-line rate, which is computed as the product of 100/estimated useful life multiplied by 2.
For each year's depreciation expense, the double rate is applied at the end of the year's balance.
For the last year, the difference between the previous year's ending balance and the residual value is taken as the depreciation expense.
Auto = $29,000
Estimated useful life = 5 years
Residual = $2,000
Depreciable amount = $27,000 ($29,000 - $2,000)
Straight-line depreciation rate = 20% (100/5)
Double-declining depreciation rate = 40% (20% x 2)
Depreciation Expense:1st year = $11,600 ($29,000 x 40%)
2nd year = $6,960 ($17,400 x 40%)
3rd year = $4,176 ($10,440 x 40%)

Fine the values of x and y.
Answer:
x = 55
y = 20
Step-by-step explanation:
Angles on a straight line sum to 180°.
Finding x
⇒ 75° + (2x - 5)° = 180°
⇒ 75 + 2x - 5 = 180
⇒ 2x + 70 = 180
⇒ 2x + 70 - 70 = 180 - 70
⇒ 2x = 110
⇒ 2x ÷ 2 = 110 ÷ 2
⇒ x = 55
Finding y
⇒ 75° + (4y + 25)° = 180°
⇒ 75 + 4y + 25 = 180
⇒ 4y + 100 = 180
⇒ 4y + 100 - 100 = 180 - 100
⇒ 4y = 80
⇒ 4y ÷ 4 = 80 ÷ 4
⇒ y = 20

After simplifying the expression, the value of y is 4.53.
In the given question,
We have to solve for y.
The given expression is 116° +15y - 4=180.
To solve for y we simplify the expression.
The expression is 116° +15y - 4=180
Now simplifying the expression.
Add 4 on both side
116° +15y - 4+4=180+4
116° +15y=184
Subtract 116 on both side
116° +15y-116°=184-116°
Simplifying
15y=184-116°
15y = 68
Divide by 15 on both side
15/15 y=68/15
y=4.53
Hence, the value of y is 4.53.

The Sample proportion for the data to construct a 95% confidence interval is 0.1351.
The percentage of red candies is (24.5%, 2.52%)
What do you mean by sample proportion?
The sample proportion (p) indicates the percentage of people in a sample who exhibit a particular quality or attribute. Divide the number of individuals (or items) who have the desired attribute by the overall sample size to obtain the sample proportion.
What is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Sample proportion [tex]=\frac{5}{37}=0.1351[/tex]
For 95% confidence interval, z = 1.96
Hence,
95% confidence interval will be:
[tex]0.1351 \pm 1.96\times \sqrt{0.1351\times(1-0.1351)/37}[/tex]
[tex]0.1351\pm0.1099[/tex]
(0.245, 0.0252)
(24.5%, 2.52%)
Since the confidence interval only contains values less than 30%.
The result is not consistent with 34% rate reported by the candy maker.

The Acme Candy Company claims that 60% of the jawbreakers it produces weigh more than 4 ounces. Suppose that 800 jawbreakers are selected at random from the production lines. Would it be unusual for this sample of 800 to contain 528 jawbreakers that weigh more than .4 ounces?
It would be unusual for this sample of 800 to contain 528 jawbreakers that weigh more than .4 ounces, using the binomial distribution, as 528 is more than 2.5 standard deviations above the mean.
What are unusual values in the binomial distribution?The binomial distribution gives the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The mean of the binomial distribution is of:
E(X) = np.
The standard deviation of the binomial distribution is of:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
The unusual measures are the ones that are more than 2.5 standard deviations from the mean.
The values of the parameters in this problem are given as follows:
p = 0.6, n = 800.
Hence the mean and the standard deviation are given as follows:
Mean: 800 x 0.6 = 480.Standard deviation: [tex]\sqrt{800 \times 0.6 \times 0.4} = 13.86[/tex]The upper bound of usual values is of:
480 + 2.5 x 13.86 = 514.65.
528 > 514.65, hence it is an unusual value.

According to the solving the probability will be 0.159.
What is probability?The area of mathematics known as probability deals with numerical assessments of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
In statistics, what exactly is a probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. In addition to being expressed in percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.
According to the given data:The incidence rate is = 0.2% or 0.002
The false negative rate is = 8% or 0.008
The false positive rate is = 1% or 0.001
The probability is
0.01*(1-0.002) + 0.95*0.002
= 0.00998 + 0.0019 = 0.01188
Probability that a person who tests positive actually has the disease would be represented as:
Let the probability be represented by = p
p * 0.01188 = 0.95 * 0.002
p = 0.0019/0.01188

Answer:
3 units left 7 units down
Step-by-step explanation:
if the sign is inside the bracket opposite sign
if the sign is outside the bracket leave it as it is
so (x+3)=0 which means x= -3 so 3 units left since it is on x axis. 7 is on y axis and since it is negative so 7 units down.
