Answer:

164 cm²

Step-by-step explanation:

Take the 2 shapes and find the areas

Triangle area = (bh)/2

                          13 × 8 × 0.5 = 52

Rectangle area = 16 × 7 = 112

Add up the areas

112 + 52 = 164

Answer:

136 cm²

Step-by-step explanation:

The composite figure is made up of a triangle and a rectangle.

Area of the triangle

\(\boxed{\begin{aligned}\textsf{Area of a triangle}&=\dfrac{1}{2} \times \sf base \times height\\\\ \implies \textsf{Area of $\triangle ABD$}&=\dfrac{1}{2} \times BD \times AB\\&=\dfrac{1}{2} \times (16-8) \times (13-7)\\&=\dfrac{1}{2} \times 8 \times 6\\&=4 \times 6\\&=24\; \sf cm^2\end{aligned}}\)

Area of the rectangle

\(\boxed{\begin{aligned}\textsf{Area of a rectangle}&=\sf width \times length\\\\ \implies \textsf{Area of rectangle $BCFE$}&= EF \times CF\\&=7 \times 16\\&=112\; \sf cm^2\end{aligned}}\)

Therefore, the area of the composite figure is:

\(\boxed{\begin{aligned}\textsf{Area of the composite figure}&=\sf Triangle + Rectangle\\ & = 24 + 112\\&=136\; \sf cm^2\end{aligned}}\)

Proportion of scrapped cans is calculated by finding the area under the normal curve outside the range of 365 cc to 375 cc. Specifications for 96% of cans is determined using z-scores and symmetric around the mean.

To calculate the proportion of scrapped cans, we need to find the area under the normal curve outside the range of 365 cc to 375 cc. This involves calculating the z-scores for both limits, finding the corresponding cumulative probabilities using a standard normal distribution table or calculator, and subtracting the two probabilities.

To determine the specifications that include 96% of all cans, we can use z-scores. We need to find the z-score that corresponds to the upper tail probability of 0.02 (since 1 - 0.96 = 0.04). Using the z-score, we can calculate the corresponding fill volume values by multiplying it with the standard deviation and adding or subtracting it from the mean.

To find the value at which the mean should be set so that 99% of all cans exceed that value, we can use the z-score corresponding to the upper tail probability of 0.01 (since 1 - 0.99 = 0.01). Using the z-score, we can calculate the desired fill volume value by multiplying it with the standard deviation and adding it to the current mean.

In conclusion, by applying the concepts of normal distribution, z-scores, and probabilities, we can determine the proportion of scrapped cans, specify ranges that include a certain percentage of cans, and set the mean value to achieve a desired proportion of cans exceeding a certain threshold.

True. a continuous random variable x assumes an (infinitely) uncountable number of distinct values.

A continuous random variable is one that can take on any value within a specified range, and it is defined over an interval of real numbers. Since the real numbers are uncountably infinite, a continuous random variable can assume an uncountable number of distinct values. In contrast, a discrete random variable can only take on a countable number of distinct values, since its possible values are restricted to a finite or countably infinite set of numbers.

"The speeds in race a are likely to be near 145 mph and the speeds in race b are likely to be near to 153 mph" correctly describes the consistency of the speeds of the cars in the two races.

Based on the given information, the box plot for race A has a larger range of speeds (from 120 to 170 mph) compared to the range of speeds in race B (from 125 to 165 mph). The box plot for race A also has a larger interquartile range (from 143 to 165 mph) compared to the interquartile range in race B (from 140 to 150 mph). However, the median speed in race A (153 mph) is lower than the median speed in race B (145 mph).

Therefore, it is not accurate to say that the speeds in race A are likely to be near 170 mph and the speeds in race B are likely to be near 165 mph. Likewise, it is not accurate to say that the speeds in race A are likely to be near 120 mph and the speeds in race B are likely to be near 125 mph.

The correct answer is that the speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near 153 mph. This is because the medians of the two box plots are relatively close to each other, and the box plot for race B has a smaller range and interquartile range, indicating greater consistency in the speeds of the cars in that race compared to race A.

The height of the isosceles triangle is 8.08 cm.

Given the sides of the triangle are:

a = 9 cm (one side of the triangle)

b = 8 cm ( base of  the triangle)

Therefore, height of the triangle =?

An isosceles triangle's height is determined by measuring perpendicularly from one vertex to the other's triangle base. A triangle's height is one of its crucial parameters since it enables us to determine the triangle's area.

we know that h = √a²₋ b²/4

substitute a and b values in the above formula, to find height:

h = √9² ₋ 8²/4

h = √81 ₋ 64/4

h = √(81 × 4) ₋ 64 / 4

h = √324 ₋ 64/4

h = √260/4

h = √65

h= 8.06 cm

Therefore the height  of the isosceles triangle is 8.06 cm.

On solving the query we can say that This stage consists just of arithmetic multiplication and does not include any specific properties of numbers.

Mathematics is concerned with numbers and their variations, equations and related structures, shapes and their places, and possible placements for them. The relationship between a collection of inputs, each of which has an associated output, is referred to as a "function". An relationship between inputs and outputs, where each input yields a single, distinct output, is called a function. Each function has a domain and a codomain, often known as a scope. The letter f is frequently used to represent functions (x). X is the input. The four main types of functions that are offered are on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

The expression's step is justified by the distributive property. The distributive property of multiplication over addition asserts that for any three integers a, b, and c, a(b + c) = ab + ac. This is the particular property we are employing.

Here are the facts:

2(5 + 17) = 2(5) + 2(17)

which is equivalent to:

2(5 • 17) = (2 • 5) 17

The distributive principle of multiplication over addition is used in this phase.

Then, we further simplify by multiplying 2 by 5 to get 10, which results in:

(2 • 5) 17 = 10 • 17 = 170.

The answer can be stated as, " When writing a decimal number that is less than 1, one must apply the trailing zero rule."

Significant figures are the number of digits placed in a number that are required to indicate the measurement of a quantity with reliability.

Significant figures have following rules,

The number of zeros lying between any two numbers are significant. For example in 301 the zero between 3 and 1 are significant.

The number of zeros lying at the end of a decimal are significant. For example, in 0.300 there zeros after 3 are significant.

A decimal number can be written as in two parts.

The first part that comes before decimal is integer.

And, the second part are the equivalent part of the order of 10.

In order to write a decimal number less than one, the number before decimal is zero.

And, the numbers coming after it are the significant figures.

Thus, the trailing zeros before a digit and decimal are significant.

Hence, trailing zero rule can be applied for the given case.

Adult=$6, Student-$6 (I got $6 for both)

Step-by-step explanation:

The difference lies in the comparison made: critical values in the z-test using rejection region(s) and the P-value in the z-test using a P-value. The choice between the two approaches depends on the nature of the population and the specific hypothesis being tested.

The correct answer is (d): In the z-test using rejection region(s), the test statistic is compared with critical values. The z-test using a P-value compares the P-value with the level of significance alpha.

The z-test is a statistical test used to assess whether a sample mean or proportion significantly differs from a hypothesized population mean or proportion. The difference between the z-test for mu (population mean) using rejection region(s) and the z-test for p (population proportion) using a P-value lies in the approach used to make the inference.

In the z-test using rejection region(s), the test statistic (calculated from the sample) is compared with critical values based on the chosen level of significance alpha. The critical values are determined from the standard normal distribution or a z-table, and if the test statistic falls within the rejection region (beyond the critical values), the null hypothesis is rejected.

On the other hand, in the z-test for p using a P-value, the test statistic is compared with the P-value. The P-value represents the probability of observing a test statistic as extreme or more extreme than the one obtained, assuming the null hypothesis is true. If the P-value is smaller than the chosen level of significance alpha, the null hypothesis is rejected.

Therefore, the difference lies in the comparison made: critical values in the z-test using rejection region(s) and the P-value in the z-test using a P-value. The choice between the two approaches depends on the nature of the population and the specific hypothesis being tested.
