A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

A rectangle is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.

A square is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.

A rhombus is a parallelogram with all congruent sides.

Since a square is a parallelogram with all congruent sides, then every square is a rhombus.

A trapezoid is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.

The statistics are z = (0.34 - 0.31) / sqrt(0.31 * 0.69 / 900) = 2.11

To answer this question, we can conduct a hypothesis test using the given sample data. The null hypothesis would be that the true proportion of chips that do not fail in the first 1000 hours is equal to or less than 31 percentage while the alternative hypothesis would be that the true proportion is greater than 31%. Using a one-tailed z-test with a significance level of 0.02, we can calculate the test statistic as follows:

z  = (0.34 - 0.31) / sqrt(0.31 * 0.69 / 900) = 2.11

Since the calculated z-value is greater than the critical value of 2.05 (corresponding to a 0.02 significance level and one-tailed test), we reject the null hypothesis and conclude that there is sufficient evidence to support the company's claim that more than 31% of the chips do not fail in the first 1000 hours of their use. In other words, we can be 98% confident that the true proportion of chips that do not fail in the first 1000 hours is greater than 31%.

Step-by-step explanation:

Radius of outer circle = R = 9 cm

Radius of inner circle = r = 5 cm

Area of the shaded region = area of the outer circle - area of the inner circle.

                                            = πR² - πr²

                                            = π(R² - r²) = 3.14*(9² - 5²)

                                             = 3.14 * (81- 25) = 3.14 * 56

                                              = 175.84 cm²

The shortest route from Ellport to Union Falls using road is 18 miles

An equation is an expression that shows the relationship between numbers and variables.

Pythagoras theorem is used to determine the measure of the sides of a right angled triangle. It is given by:

(hypotenuse side)² = (adjacent side)² + (opposite side)²

The distance from Larksville to Smithfield = 9 + 9 + 6 = 24 miles

The distance from Larksville to Union Falls = 19.5 + 6.5 = 26 miles

Let x represent the distance from Smithfield to Union falls, using Pythaoras:

26² = 24² + x²

x² = 100

x =  10 miles

the distance from Smithfield to Union falls is 10 miles.

Let y be the shortest route from Ellport to Union Falls, using Pythagoras:

y² = 10² + (9 + 6)²

y² = 10² + 15²

y² = 325

y = 18 miles

The distance from Ellport to Union Falls is 18 miles

Answer:

D: 15.75

A: -14.84

C: x = 11

Step-by-step explanation:

Two negatives make a positive, do 7.2 + 8.55 and you will get 15.75. If it's easier, do -10.5 + -4.34 to get -14.84. For number three you have to distribute 1/2 to x and 1 to get 0.5x + 0.5 = -5. Subtract -0.5 on both sides to get 0.5x = 5.5. Divide 0.5 from both sides to get 11.

Answer:

x = 72°

Step-by-step explanation:

Since the triangle has 2 congruent sides then it is isosceles and the 2 base angles are congruent , both 54° , then

x = 180° - (54 + 54)° = 180° - 108° = 72°

For the sample of weight of corn chips dispensed in dispensing machine, probability that the sample mean weight of these 100 bags falls between 10.50 and 10.80 ounces is equals to 0.4332.

We have a sample of weight of corn chips dispensed by the dispensing machine.

Dispensed weight of bag by the dispensing machine = 10 ounces

The sample of weight of bags follows the normal distribution with, sample mean, \( \bar x\) = 10.5 ounces

standard deviations = 2 ounces

Randomly selected from this dispensing machine. Sample size, n = 100

We have to determine probability that the sample mean weight of these 100 bags falls between 10.50 and 10.80 ounces,

\(P( 10.50 < \bar x < 10.80),\)

Using Z-score formula for sample mean in normal distribution, \(Z = \frac{ \bar x - \mu}{ \frac{\sigma}{\sqrt{n}} }\)

where μ--> population mean

σ -->standard deviations

n --> Sample size

Now, the required probability is \(P( 10.50 < \bar x < 10.80)\)

= \(P(\frac{ 10.50 - \mu }{\frac{\sigma}{\sqrt{n}}} < \frac{ \bar x - \mu}{ \frac{\sigma}{\sqrt{n}} } < \frac{ 10.80 - \mu }{\frac{\sigma}{\sqrt{n}}} )\)

= \(P(\frac{ 10.50 - 10 }{\frac{2}{\sqrt{100}}} < z< \frac{ 10.80 - 10 }{\frac{2}{\sqrt{100}}} )\)

= \(P(\frac{ 0.50 }{\frac{2}{10} }< z< \frac{ 0.80 }{\frac{2}{10}})\)

= \(P(2.5 < z< 4)\)

= 0.4332

Hence, required value is 0.4332.

Answer:

y = 2

`sin ( a ) = sqrt(14593)/97``cos ( a ) = 72/97``tan ( a ) = sqrt(14593)/72``sec ( a ) = 97/72``csc ( a ) = 97/sqrt(14593)``cot ( a ) = 72/sqrt(14593)`

Given that `b=72` and `c=97`

We can use the pythagorean theorem to find the length of side 'a'.

Let `a=x`so we have;`b^2+c^2=a^2`Substitute the values of `b` and `c`;`72^2+97^2=a^2`

Simplify and solve for `a`;`5184+9409=a^2`Adding, we get`14593=a^2`Taking the square root on both sides, we get;`a=sqrt(14593)`

The values of the sine, cosine, tangent, secant, cosecant, and cotangent of angle `a` in the triangle with sides `a= sqrt(14593)`, `b=72` and `c=97` are given as;`

sin ( a ) = a/c = sqrt(14593)/97` `cos ( a ) = b/c = 72/97` `tan ( a ) = a/b = sqrt(14593)/72` `sec ( a ) = c/b = 97/72` `csc ( a ) = c/a = 97/sqrt(14593)` `cot ( a ) = b/a = 72/sqrt(14593)`

The actual weight is 0.0042 pounds lighter than the labeled weight.

The actual weight of the chocolates is 0.3798 pounds, while the label on the bag states it should weigh 0.384 pounds. To determine how much lighter the actual weight is, we can calculate the difference between the two weights.

Subtracting the actual weight from the labeled weight, we get:

0.384 pounds - 0.3798 pounds = 0.0042 pounds.

Therefore, the actual weight is 0.0042 pounds lighter than the labeled weight.

It's important to note that this difference may seem small, but it can be significant depending on the context. Accuracy in labeling is crucial for various reasons, such as complying with regulations, providing precise information to consumers, and ensuring fair trade practices. Even minor discrepancies can impact trust and customer satisfaction.

area = 17×4= 68km²'&&&&&&

The area of trapezium; = ½(a+b)h

where a= 12 km

B= 17-12 = 5 km

The sale price of an item that is regularly priced at $91 and is on sale for 35% off the regular price using the aleks calculator is $59.15.

To calculate the sale price of an item that is regularly priced at $91 and is on sale for 35% off the regular price using the aleks calculator we will follow these steps:

Step 1: Calculate the amount of discount = Regular Price × Discount rate

Discount rate = 35/100

Simplifying the value we have:

Discount rate = 0.35

Amount of discount = 91 × 0.35

Amount of discount = $31.85

Step 2: Calculate the sale price

Sale price = Regular price − Amount of discount

Sale price = $91 − $31.85

Sale price = $59.15

Hence, the sale price of an item that is regularly priced at $91 and is on sale for 35% off the regular price using the aleks calculator is $59.15.
