Answer: 1/50

Step-by-step explanation:

Step 1: We need to multiply the numerator and denominator by 100 since there are 2 digits after the decimal.

0.02 = (0.02 × 100) / 100

= 2 / 100 [ since 0.02 × 100 = 2 ]

Step 2: Reduce the obtained fraction to the lowest term

Since 2 is the common factor of 2 and 100 so we divide both the numerator and denominator by 2.

2/100 = (2 ÷ 2) / (100 ÷ 2) = 1/50

Answer:

2/5 < 1/2

Step-by-step explanation:

First, find the LCM for both denominators because you can't multiply 2 to get to 5. The LCM of 5 and 2 are 10, so you put that as their denominator. Then you have to think what you multiplied by 5 or 2 to get 10. For 2/5, you multiplied 5 by 2 to get 10, so multiply the numerator by 2 too. For 1/2, you multiplied 2 by 5 to get 10, so multiply the numerator by 5. Now, you will have 4/10 and 5/10. It's pretty obvious that 5/10 is bigger than 4/10, so the correct answer is 2/5 < 1/2

Answer: (a + 10)(a - 10)

The expression (x - 8) is not the factor of the polynomial x⁶ - 64x⁴ + x² - 7x - 51.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The polynomial is given below.

⇒ x⁶ - 64x⁴ + x² - 7x - 51

If the value of the polynomial is zero at x = 8. Then (x - 8) will be the factor of the polynomial.

At x = 8, the value of the polynomial is given as,

⇒ (8)⁶ - 64(8)⁴ + (8)² - 7(8) - 51

⇒ 262,144 - 262,141 + 64 - 56 - 51

⇒ - 43

The expression (x - 8) is not the factor of the polynomial x⁶ - 64x⁴ + x² - 7x - 51.

The MPOS expression for the given function is f(a, b, c, d) = ab' + ab + cd' + cd.

To find the minimum product of sums (MPOS) expression using a Karnaugh map for the given function:

f(a, b, c, d) = Em(1, 3, 5, 7, 8, 9, 11, 13, 15)

Now, we group the adjacent cells with 'X' to form the largest possible groups, which will represent the terms in the MPOS expression.

In this case, we have the following groups:

Group 1: 8, 9, 10, 11, 12, 13, 14, 15

Group 2: 3, 7, 11, 15

Next, we convert each group into a sum-of-products (SOP) expression:

Group 1: (ab'cd') + (ab'cd) + (abcd') + (abcd) + (abcd') + (abcd) + (abcd') + (abcd)

       = ab' + ab + cd'

Group 2: (ab'c'd') + (ab'cd') + (ab'c'd) + (ab'cd) + (abcd') + (abcd)

       = ab' + ab + cd

Finally, we combine the SOP expressions for each group to obtain the minimum product of sums (MPOS) expression:

f(a, b, c, d) = (ab' + ab + cd') + (ab' + ab + cd)

Therefore, the MPOS expression for the given function is f(a, b, c, d) = ab' + ab + cd' + cd.

Step-by-step explanation:

Sample size required is 333, 42, 97 and 33,285, respectively using  confidence level and different parameters of standard deviation.

To estimate a population mean to within 40 units with 99% confidence and a population standard deviation of 200, the sample size required can be calculated using the formula

n = (Zα/2)² * (σ²) / (E²)

where Zα/2 is the z-score corresponding to the desired level of confidence (99% in this case), σ is the population standard deviation, and E is the desired margin of error (40 units).

Plugging in the values, we get

n = (2.576)² * (200)²/ (40)²

n = 332.84

Therefore, a sample size of at least 333 should be used.

If the population standard deviation is changed to 50, the same formula can be used with the new value of σ:

n = (2.576)² * (50)²/ (40)²

n = 41.68

Therefore, a sample size of at least 42 should be used.

If using a 95% confidence level, the z-score changes to 1.96

n = (1.96)² * (200)²/ (40)²

n = 96.04

Therefore, a sample size of at least 97 should be used.

To estimate the population mean to within 10 units, the margin of error (E) is changed to 10 in the formula, and the sample size is recalculated

n = (2.576)² * (200)² / (10)²

n = 33,284

Therefore, a sample size of at least 33,285 should be used.

The required sample size should be 166 to estimate the population mean within 40 units with 99% confidence, given a population standard deviation of 200.

To determine the required sample size for estimating a population mean with a given level of confidence and margin of error, we can use the formula:

n = (Z * σ / E)^2

Where:

n = Sample size

Z = Z-score corresponding to the desired confidence level (in this case, 99% confidence corresponds to a Z-score of 2.576)

σ = Population standard deviation

E = Margin of error (in this case, 40 units)

Substituting the given values into the formula, we have:

n = (2.576 * 200 / 40)^2

Simplifying further:

n = (12.88)^2

n ≈ 165.6544

Since the sample size must be a whole number, we round up the value to the nearest integer:

n = 166

Therefore, the required sample size should be 166 to estimate the population mean within 40 units with 99% confidence, given a population standard deviation of 200.

The relationship between the number of months after the first year and the amount remaining on the card is y = - 2.5 x + 25.

The independent variable is number of months after the first year.

The dependent variable is the amount remaining on the card.

The relationship between the number of months after the first year would be:

Amount remaining = Starting value - ( Amount decreasing by x Number of months )

y = 25 - ( 2. 50 x )

This can be written as:

y = - 2. 50 x + 25

The independent variable is the x value and as shown above, this is the number of months after the first year. This then means that the dependent variable would the amount remaining.

The perimeter first figure that is made of a square and equilateral triangle is 52 cm.

What exactly are squares?

A square is a two-dimensional planar shape with four equal sides and four 90-degree angles. The features of a rectangle are similar to those of a square, but the distinction is that a rectangle has just its opposing sides equal.

A square's most significant qualities are

The diagonal of a square is divided into two isosceles triangles.

Square area=(side)²

Square perimeter=4*side

Now,

For first figure given that

sides of square are 14 cm in length

and length of side of equilateral triangle are=5 cm

but for finding perimeter of the figure only 3 sides of square and 2 sides of triangle are needed.

So, perimeter=3*14+2*5

=42+10

=52 cm

Joseph needs 22.4 packets of orange drink mix which requires one packet of orange drink mix for every half gallon.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

We have been given that Joseph is mixing 5 1/2 gallons of orange drink for his class picnic.

And every 1/2 gallon requires 1 packet of orange drink mix.

We have to determine the number of packets of orange drink mix Joseph needs.

Let the number of packets of orange would be x

We can write this as a ratio as

1/2 gallon : 1 packet = 5 1/2 gallons : x packets

0.5 gallon : 1 packet = 11.2 gallons : x packets

⇒ x = 11.2/0.5

The impact of using a different confidence level when computing a confidence interval about a parameter based on sample data is that a higher confidence level will result in a wider confidence interval.

A confidence interval is a range of values within which we expect the true parameter to lie with a certain level of confidence. The confidence level represents the probability that the interval will capture the true parameter. When a higher confidence level is used, such as 95% instead of 90%, the interval needs to be wider to provide a higher level of confidence. This means that there is a greater probability of capturing the true parameter within the interval, but the interval itself will be larger, allowing for more variability in the estimates. Conversely, a lower confidence level will result in a narrower interval, providing less certainty but a more precise estimate.
