Answer:

the total area under the normal distribution is 0.0684.

Step-by-step explanation:

We can use a standard normal distribution table or a calculator to find the areas S₁ and S₂.

Using a standard normal distribution table or calculator, we find:

S₁ = 0.0158

S₂ = 0.0526

To find the total area S₁ + S₂, we simply add these two values:

S₁ + S₂ = 0.0158 + 0.0526 = 0.0684

Therefore, the total area under the normal distribution is 0.0684.

The hypothesis for the given scenario can be written as follows:

Null hypothesis

H_0: μ = 7.2

Alternative hypothesis

H_1: μ ≠ 7.2

Here, μ = Population mean

The mean pressure produced by the valve is not 7.2 lbs/square inch.

The given level of significance (α) = 0.05

The given population variance is known to be 1.

Need to determine if there is sufficient evidence to show that the valve does not perform to the given specifications if the valve was designed to produce a mean pressure of 7.2 lbs/square inch. That is, whether to reject or accept the null hypothesis with the given level of significance (α) = 0.05.

The sample mean pressure of 190 engines tested was 7.3 lbs/square inch. Mean pressure (μ) = 7.3 lbs/square inch, σ² = Variance = 1, n = Number of observations = 190

Significance level (α) = 0.05

Test Statistic: Z = (x - μ) / (σ / √n)

where x = Sample mean

The formula for the test statistic can be written as:

Z = (7.3 - 7.2) / (1 / √190)Z = 4.3588 (approx.)The calculated value of Z = 4.3588 is greater than the Z critical value at 0.05 level of significance.

Hence, there is sufficient evidence to reject the null hypothesis H_0. Therefore, we can conclude that the valve does not perform to the given specifications. The mean pressure produced by the valve is not 7.2 lbs/square inch.

To estimate the number of rubber balls in the whole basket, we can multiply this proportion by the total number of balls. Therefore, We can estimate that there are about 21 rubber balls in the basket.

An average proportion is the sum of a set of proportions divided by the number of proportions.

It represents the average or typical value of the proportions in the set, and can be used to estimate the overall proportion or percentage of a larger population.

To estimate how many of the balls in the basket are rubber, we can use the proportion of rubber balls that were drawn in each class to find the average proportion of rubber balls across all four classes.

We can then use this average proportion to estimate the number of rubber balls in the whole basket.

The total number of balls drawn from the basket is:

(2 + 8) + (4 + 6) + 2 x (3 + 7) = 40

The total number of rubber balls drawn is:

2 + 4 + 2 x 3 = 12

The proportion of rubber balls drawn in each class is:

Class 1: 2/10 = 0.2

Class 2: 4/10 = 0.4

Class 3: 3/10 = 0.3

Class 4: 3/10 = 0.3

The average proportion of rubber balls across all four classes is:

(0.2 + 0.4 + 0.3 + 0.3) / 4 = 0.3

Therefore, we can estimate that approximately 30% of the balls in the basket are rubber. To estimate the number of rubber balls in the whole basket, we can multiply this proportion by the total number of balls:

Number of rubber balls = 0.3 x 70 = 21.

The correct statements are:

B. Jessie’s pyramid has a volume of 525 in^3. (Using the formula for the volume of a pyramid, V = (1/3) * base area * height, we get V = (1/3) * 15^2 * 7 = 525 in^3.)

D. Carl’s pyramid is 3.6 times larger than Jessie’s. (Using the formula for the volume of a square pyramid, V = (1/3) * base area * height, we can find the base side length of Carl's pyramid: base side length = sqrt((3*1890)/(7*15^2)) ≈ 18.46 inches. Therefore, the ratio of volumes is (18.46/15)^2 * (7/7) ≈ 3.6.)

Step-by-step explanation:

For a continuous function, if the second derivative at the critical points is negative, then it not necessarily mean that it is quasi-concave.

A "continuous-function" is defined as a function in which small changes in the input result in small changes in the output, without any abrupt jumps or discontinuities.

A function is termed as "quasi-concave" if its upper contour sets are convex.

A function is termed as "quasi-convex" if its lower contour sets are convex.

The "Quasi-concavity" is a weaker condition than concavity, so it does not exhibit in a condition on the sign of "second-derivative".

Therefore, if a continuous function has a negative second derivative at its critical points, it does not necessarily mean that it is quasi-concave.

The pairs of lines are classified as: perpendicular, parallel, neither, neither.

The slopes of the first pair of lines differ, making them neither parallel nor perpendicular. The slopes of the first and second lines are 1/2 and -2, respectively.

The second set of lines is perpendicular because the slopes of the first line, which is -3, and the second line, which is 1/3, are the opposites of each other.

The third set of lines have varying slopes and are neither equal nor perpendicular. The slopes of the two lines are -2/3 for the first line and 6/4 for the second, which reduces to 3/2.

To classify each pair of lines as parallel, perpendicular, or neither, we need to compare their slopes.

2y = x and y = -2x + 6

The first equation can be written in slope-intercept form as y = (1/2)x, which means its slope is 1/2. The second equation can be written in slope-intercept form as y = -2x + 6, which means its slope is -2. Since the slopes are negative reciprocals of each other, these lines are perpendicular.

y + 3x = 1 and 2y = -6(x - 1)

The first equation can be written in slope-intercept form as y = -3x + 1, which means its slope is -3. The second equation can be written in slope-intercept form as y = -3x + 3, which means its slope is also -3. Since the slopes are the same, these lines are parallel.

3y + 2x = -3 and 4y = 6x + 12

The first equation can be written in slope-intercept form as y = (-2/3)x - 1, which means its slope is -2/3. The second equation can be written in slope-intercept form as y = (3/2)x + 3, which means its slope is 3/2. Since the slopes are not equal and not negative reciprocals of each other, these lines are neither parallel nor perpendicular.

y + 2 = 5x and 5y - x = -2

The first equation can be written in slope-intercept form as y = 5x - 2, which means its slope is 5. The second equation can be written in slope-intercept form as y = (1/5)x - 2/5, which means its slope is 1/5. Since the slopes are not equal and not negative reciprocals of each other, these lines are neither parallel nor perpendicular.

The measures of the angle m∠DAB for the isosceles trapezoid is equal to 75°.

This is a trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. The opposite angles are supplementary which implies they sum up to 180°.

The upper base angles m∠DAB and m∠ADC are equal, and angles m∠ADC and m∠DCB are supplementary, so we shall calculate for the angle m∠DAB by first evaluating for angle m∠ADC as follows:

m∠ADC + m∠DCB = 180° {opposite angles are supplementary}

m∠ADC + 105° = 180°

m∠ADC = 180° - 105° {subtract 105° from both sides}

m∠ADC = 75°

m∠ADC = m∠DAB = 75°

Therefore, the measures of the angle m∠DAB for the isosceles trapezoid is equal to 75°.

Largest angle- 115

Smallest angle-65

Smallest angle-65

Step-by-step explanation:

Angles of opposite sides in a parallelogram are equal.

Let the smallest angle be y.

Let the largest angle be y+50

y+50+y+50+y+y=360

100+4y=360

4y=(360-100)/4

y=65

Theyre four angles:

50+y(65)= 115

50+y(65)= 115

y=65

y=65

Answer: 65° and 115°.

Step-by-step explanation:

Let the smallest angle is x°

Hence the largest angle is x°+50°

The sum of the angles in a parallelogram that are adjacent to one side is 180 degrees.

Therefore

x°+(x°+50°)=180°

2x°+50°=180°

2x°+50°-50°=180°-50°

2x°=130°

Divide both parts of the equation by 2:

x°=65°

x°+50°=65°+50°

x°+50°=115°.

Width = 10

Step-by-step explanation:

let length = X

width = 3X - 2

Area = length x width

40 = X x (3X - 2)

40 = 3X^2 - 2X

therefore 3X^2 - 2x - 40 = 0

3x^2 + 10x - 12x - 40 = 0

x(3x + 10) - 4(3x + 10) = 0

(x - 4) (3x + 10) = 0

(x - 4) = 0

x = 4

(3x + 10) = 0

3x = - 10

x = -10/3

Since the lenght can't be negative, we'll work with x = 4

Therefore the width = 3x - 2

Width = 3(4) -2

Width = 12 - 2

Width = 10

Step-by-step explanation:

The number of insects consumed by pitcher plants is essential for their survival and growth, and it is fascinating to observe this unique aspect of their carnivorous nature.

Pitcher plants are carnivorous plants that trap and digest insects to obtain nutrients. The exact number of insects consumed by pitcher plants in a month can vary depending on factors such as the species of pitcher plant, its size, and the local environment. However, studies have estimated that a single pitcher plant can consume anywhere from a few dozen to hundreds of insects per month.

The mechanism of the pitcher plant is quite interesting. Insects are lured into the plant by its color and sweet-smelling nectar. Once inside, the insect becomes trapped and is unable to escape due to the slippery inner walls of the pitcher. The plant then secretes digestive enzymes that break down the insect's tissues, allowing the plant to absorb the nutrients.

Interestingly, not all insects are consumed by pitcher plants. They tend to prefer smaller insects such as ants and flies, but larger insects such as bees and wasps may occasionally become trapped as well.
