Answer:

the answer is 488 of the composite figure is 488

The equation x + (60 + 70)° = 180° is used to solve for the measure of the vertical angle x = 50°

Vertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.

The angle y and x form vertical angles, so x = y

Angle y form a straight line with 60° and 70° so we have the equation to solve for x as:

x + 60° + 70° = 180° {sum of angles on a straight line}

x + 130° = 180°

x = 180° - 130° {subtract 139° from both sides}

x = 50°

Therefore, the measure of the vertical angle x is equal to 50° derived with the equation x + (60° + 70°) = 180°.

The numbers that do not form a fact family are solved

Given data ,

A fact family consists of a set of related addition and subtraction facts that use the same numbers. For example, the numbers 3, 5, and 8 form a fact family because:

3 + 5 = 8

5 + 3 = 8

8 - 5 = 3

8 - 3 = 5

Numbers that do not form a fact family are any set of numbers that do not follow this pattern. For example, the numbers 2, 4, and 7 do not form a fact family because no combination of addition and subtraction using these numbers produces the other two numbers.

The correct inverse Laplace transform for the given expression is option (e) 3tet + 2e2t.

The inverse Laplace transform is a mathematical operation that allows us to convert a function in the Laplace domain back to the time domain. In this case, we have to find the inverse Laplace transform of the given expression.

To solve this, we can use the properties and formulas of Laplace transforms:

The Laplace transform of e-at is 1/(s-a).

The Laplace transform of t^n is n!/(s^(n+1)).

Based on these formulas, the inverse Laplace transform of 3tet can be found as 3/(s-2)^2 and the inverse Laplace transform of 2e2t can be found as 2/(s-2).

Combining these two terms, we get the inverse Laplace transform of 3tet + 2e2t as 3/(s-2)^2 + 2/(s-2).

Finally, we need to convert this expression back to the time domain by taking the inverse Laplace transform of each term. Applying the inverse Laplace transform formulas, we obtain 3te2t + 2e2t as the final result.

Therefore, the correct answer is option (e) 3tet + 2e2t.

The probability of committing a Type I error in this scenario is 0.05 or 5%. The probability of committing a Type I error is equal to the significance level (α) chosen for the test.

To find the probability of committing a Type I error when testing the claim that μ < 16, with a significance level of α = 0.05 and a sample size of n = 45, we need to calculate the critical value or the z-score corresponding to the significance level.

Since the alternative hypothesis is μ < 16, this is a left-tailed test.

The critical value or z-score can be found using the standard normal distribution table or a statistical software. For a significance level of α = 0.05 (or 5%), the critical value corresponds to the z-score that leaves a probability of 0.05 in the left tail.

Using the standard normal distribution table, the critical z-score for a left-tailed test with a significance level of 0.05 is approximately -1.645.

The probability of committing a Type I error can be calculated as the probability of observing a test statistic (z-score) less than -1.645 when the null hypothesis is true. This probability is equal to the significance level (α).

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

A pair of triangles are said to be similar if two pairs of corresponding angles in those triangles are congruent. We can conclude that the third pair must also be equal if the first two angle pairs are. When all three pairs of angles are equal, the sides of the three triangles must also be proportionate.

with your square root symbol I never know what is inside the square root and what is possibly outside.

so, I can only guess and see what comes close.

f(x) = 2x² + x - 1

g(x) = sqrt(2x - 1) ??? is that so ?

g(f(x)) means that the whole f(x) expression is used as x in g(x).

The odds in favor of rolling two number cubes and having a 7 will be 1/6.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

The total number of the events will be

Total events = 6 x 6

Total events = 36

The number of favorable events will be

Favorable events = 6 {(1, 6), (2, 5), (3, 4), (4, 3), (2, 5), (6, 1)}

Then the probability will be

P = 6 / 36

P = 1/6

To determine whether Melissa can apply two coats of paint to the entire sculpture with a can of spray paint that covers 6,500 square centimeters need to consider the surface area of the sculpture and the amount of paint required for two coats.

Let's assume the sculpture has a total surface area of S square centimeters.

To apply one coat of paint to the entire sculpture, Melissa would need approximately S square centimeters of paint.

The can of spray paint covers 6,500 square centimeters, it would be sufficient to cover the sculpture with one coat.

A second coat of paint, Melissa would need an additional S square centimeter of paint.

The first coat has already covered the sculpture, the second coat would only require coverage of any missed spots or areas that need additional touch-up.

The amount of paint required for the second coat would generally be less than the amount required for the first coat.

Considering these factors, it is likely that Melissa can apply two coats of paint to the entire sculpture with a can of spray paint that covers 6,500 square centimeters.

The actual feasibility would depend on the size and complexity of the sculpture, as well as the efficiency of Melissa's painting technique.

If the sculpture has a significantly larger surface area than 6,500 square centimeters, or if it has intricate details that require a substantial amount of touch-up, Melissa may require additional cans of spray paint to achieve two coats.
