Answer:

115 apples were picked last year

Step-by-step explanation

It says there are 50% more apples picked this year than last year. So, we divide 230 by 2 because 50% is half of 100%. 230÷2 = 115

115 apples

Resultant speed of the motorboat is 9.4 m/s.

Pythagorean theorem states that the squared value of longest side in an right angle triangle will be equal to the addition of the squared value of two smaller sides. Thus, the resultant speed of the boat is 9.4 m/s

This is the concept of application of the pythagorean theorem.

The boat is traveling in the east direction at a speed of 8 m/s but the river has a northward current of 5 m/s. We know than both the directions (East and North) are perpendicular to each other. The bend tending toward east but the river slows down the speed and makes the boat tending toward north-east.

Thus, by applying Pythagorean theorem, the resultant speed can be calculated as:

c² = a² + b²

c² = 8² + 5²

c² = 64 + 25

c² = 89

c = [tex]\sqrt{89}[/tex]

c = 9.4 m/s

Hence, the resultant speed of boat is 9.4 m/s.

To find the value of q, we can use the point-slope form of a line:

y - y1 = m(x - x1)

where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) is a second point on the line.

In this case, we have the slope of the line as -9 and the point ( -9, 1), so we can plug in the values:

y - 1 = -9 (x - (-9))

Expanding and solving for y, we get:

y = -9x + 90

Next, we want to find the value of y when x = -10. Substituting this value into the equation:

q = -9(-10) + 90

Solving for q:

q = -90 + 90 = 0

So, the value of q is 0.

The median is the midpoint of the distribution. it is the number such that half of the observations fall above it, and half fall below it.

The following statement is correct.

The median M of a distribution is the number at which half of the observations are smaller and half are greater.

For skewed distributions or distributions containing outliers, the median is the most useful metric of central tendency. For example, in highly skewed income distributions, the median is frequently utilised as a measure of central tendency.

For normal distributions, the mean is employed. For skewed distributions, the median is typically utilised. The mean is not a reliable tool since it is heavily impacted by outliers. Because it is far more robust and comprehensible, the median is better suited for determining central tendency from skewed distributions.

The gross pay for the given service is $1307.6.

Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages.

Given that, the regular salary of some service is $1100, we need to calculate the gross payment with over time rate, which is $10.38 per hour (20 hours overtime to be paid)

Therefore,

To find, gross payment, we will multiply by 10.38 by 20, and add to regular salary,

Gross payment = 10.38 × 20 = 207.6 + 1100

= 1307.6

Hence, the gross pay is $1307.6

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

Rate of reduction = 100 - 3.25 = 96.75%

After 6 years, the reduction in trees =0 .9675^6

The probability of selecting 4 defective calculators is 0.0009.

The probability of selecting 4 defective calculators out of a group containing 47 defective and 29 non-defective calculators can be calculated using the formula for a combination. The formula is n!/r!(n-r)! where n is the total number of items and r is the number of items being selected. In this case, n is 76 (47 defective + 29 non-defective) and r is 4. Therefore, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.

To calculate this answer, the first step is to calculate the total number of combinations that can be made using 4 items out of 76 items. This is calculated using the formula n!/r!(n-r)!. The numerator, n!, is equal to 76! which is equal to 5.43e+102. The denominator, r!(n-r)!, is equal to 4!(76-4)! which is equal to 5.90e+09. By dividing the numerator by the denominator, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.

Jennifer has 48 nickels, which means she has 144 quarters.

Let's call the number of nickels Jennifer has "n".

Since Jennifer has three more dimes than nickels, she has n + 3 dimes.

And since she has three times as many quarters as nickels, she has 3n quarters.

We can start by figuring out the total value of the nickels and dimes in terms of cents:

n * 5 cents + (n + 3) * 10 cents = 750 cents

Expanding the right side of the equation and solving for n:

5n + 10n + 30 cents = 750 cents

15n + 30 cents = 750 cents

15n = 720 cents

n = 48

So Jennifer has 48 nickels, which means she has 3 * 48 = 144 quarters.

The value of k is 3.

Quadratic functions are polynomial functions of second degree.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given is a quadratic function,

y = 2x² - 8x + 7

This function is identical to some function y = a(x - h)² + k

We have to write the given quadratic function in the form y = a(x - h)² + k.

2x² - 8x + 7 = (2x² - 8x) + 7

                   = 2(x² - 4x) + 7

                   = 2(x² - 4x + 4) + 7 - 4

We have the algebraic identity, (a - b)² = a² - 2ab + b²

                   = 2 (x - 2)² + 3

a = 2, h = 2 and k = 3

A. The y-intercept is at the point (0, 0).

B.  The zeros are x = 0 or x = ±√5

C.

A) The y-intercept of this graph is the point where x = 0.

When  x = 0, the value of y

= 0^4 - 5*0^2

= 0.

Therefore, the y-intercept is at the point (0, 0).

B) The x-intercepts/roots of the function are the values of x that make y = 0.

To find these values, we need to set y = 0 and solve for x:

x⁴ - 5x² = 0

x⁴ = 5x²

x² = x⁴/5

x = ±√(x⁴/5)

We can simplify this expression by factoring x² out of both sides:

x²(x² - 5) = 0

x² = 0 or x² - 5 = 0

x = 0 or x = ±√5

hence the x-intercepts are at x = 0 and x = ±√5.

Justin used average two rolls of ribbon in total, using 1/5 of one and 2/5 of another.

Justin had 3 rolls of ribbon before he started tying parcels and presents. He used 1/5 of a roll of ribbon to tie a parcel, and then used 2/5 of another roll of ribbon to tie a present. This means that he used two rolls of ribbon in total, with 1/5 of one and 2/5 of the other. He still has one roll of ribbon remaining, meaning that he didn't use all three rolls of ribbon. To calculate the total amount used, you would need to multiply 1/5 and 2/5 by the length of the ribbon, or alternatively multiply the two fractions together to get 2/5 of a roll of ribbon used.

The Fréchet distance is a mathematical metric for comparing the similarity of curves that takes into account the position and arrangement of curve points. Maurice Fréchet is honored by having his name used. The pairs of points that make up the Fréchet distance sweep continuously along their respective curves, so the Fréchet metric takes the flow of the two curves into account. As a result, the Hausdorff distance and other similarity measures for arbitrary point sets are inferior to the Fréchet distance for curves. Two curves might have a small Hausdorff distance but a large Fréchet distance.
