The score on the remaining test was 85.

Let's denote the score on the remaining test by x. Then, we know that the average of all seven tests is 78, so we can use the formula for the mean:

(72 + 82 + 84 + 66 + 68 + 89 + x) / 7 = 78

Multiplying both sides by 7, we get:

72 + 82 + 84 + 66 + 68 + 89 + x = 546

Adding up the six scores we know, we get:

(72 + 82 + 84 + 66 + 68 + 89) = 461

Substituting this into the previous equation, we have:

461 + x = 546

Subtracting 461 from both sides, we get:

x = 85

Therefore, the score on the remaining test was 85.

The remainder when a 90-digit number 9999 is divided by 89 is 0, as the result of applying the divisibility rule of 89, which involves reversing the digits of the number and subtracting the smaller from the larger.

To find the remainder when a 90-digit number 9999 is divided by 89, we can use the divisibility rule of 89. The rule states that for any integer n, the number obtained by reversing the digits of n and subtracting the smaller from the larger is divisible by 89.

In this case, we reverse the digits of 9999 to get 9999 again, and subtract the smaller from the larger to get 0. Since 0 is divisible by any number, including 89, the remainder when 9999 is divided by 89 is 0.

The probability that a randomly selected band member is a senior given that he or she plays the trumpet is 34.78%.

Probability is defined as the likeliness of an event to happen. It can be calculated by dividing the total desired outcomes by the total outcomes.

P = desired outcomes / total outcomes

Of the 108 band members, if 23 play the trumpet, and 8 are seniors who play the trumpet, then the probability that a randomly selected band member is a senior given that he or she plays the trumpet is 8 divided by 23.

P = 8/23 x 100

Therefore, the function f(x) is given by: f(x) = -x ln|24x - 12x^2| + 14x + 6.

To find the function f(x) given f''(x) = -2/(24x - 12x^2), f(0) = 6, and f'(0) = 14, we need to integrate f''(x) twice and apply the initial conditions.

First, integrate f''(x) with respect to x to find f'(x):

∫(-2/(24x - 12x^2)) dx = -ln|24x - 12x^2| + C1,

where C1 is the constant of integration.

Next, integrate f'(x) with respect to x to find f(x):

∫(-ln|24x - 12x^2| + C1) dx = -x ln|24x - 12x^2| + C1x + C2,

where C2 is the constant of integration.

Now, we can apply the initial conditions:

f(0) = 6, so we substitute x = 0 into the equation:

-0 ln|24(0) - 12(0)^2| + C1(0) + C2 = 6,

C2 = 6.

f'(0) = 14, so we substitute x = 0 into the derivative equation:

-ln|24(0) - 12(0)^2| + C1 = 14,

C1 = 14.

In the balance sheet, mortgage notes payable are reported as a long-term liability only.

Mortgage notes payable represent the amount owed by a company for a mortgage loan. These loans are typically long-term obligations that are expected to be repaid over an extended period, often several years. Therefore, mortgage notes payable are classified as long-term liabilities in the balance sheet.

Current liabilities are obligations that are expected to be settled within a short period, usually one year or less. Since mortgage notes payable typically have a longer repayment term, they do not meet the criteria to be classified as current liabilities.

By reporting mortgage notes payable as a long-term liability, the balance sheet provides a clear distinction between the company's short-term and long-term obligations, helping stakeholders understand the company's financial position and obligations over different time horizons.

Answer:

Step-by-step explanation:

Answer:When you play every beat (1, 2, 3, 4) on the snare it’s often called “four on the floor”. True four on the floor would seem to be a bass hit on every beat, like in disco, but don’t let that confuse you. It’s the same musical concept.

“Pretty Woman” is a good example of a four on the floor. I don’t know if four on the floor is exactly a style, because I hear it in classic soul, punk and whatever, but it’s definitely an approach. It’s a way to mix it up, maybe adding a little tension or forward motion without turning up the metronome. The Stooges’ “I Wanna Be Your Dog” is a good example of a song that half-way commits to the four on the floor, and the resulting feel is kind of like falling or stumbling

The 95 percent confidence interval for the mean (μ) is (31.19, 34.41).

What is standard deviation?

A measure of a group of values' variance or dispersion in statistics is called the standard deviation. The values tend to be close to the set's mean when the standard deviation is low, while the values are dispersed over a larger range when the standard deviation is high.

Given: A random sample of size 30 from a normal population yields a sample mean of 32.8.

The population standard deviation is known to be 4.51.

X bar = 32.8

s = 4.51

We have to construct a 95 percent confidence interval for the mean (μ).

So, the interval is,

32.8 ± 1.96 (4.51 / √30) = 31.19 to 34.41

Hence, the 95 percent confidence interval is, (31.19, 34.41).

**Questions may use different units to try to trick you, such as weeks and days! But, they are the same.**

Okay, so now we have gathered the information we know, now lets make the math equation. First we need to make the variables. Let's let G equal how many baskets she made on day 14.

G = 10+(14x4)

G = 10+(56)

G = 66

The slope of the line represented by 4x-7y=62 is 4/7. A line's steepness is measured by its slope. The mathematical expression for slope is "rise over run."

Option A is correct.

In mathematics, a line's slope is the ratio of the change in the y coordinate to the change in the x coordinate. The net change in the y-coordinate and the net change in the x-coordinate, respectively, are denoted by the symbols delta y and delta x.

          We are given equation as 4x-7y=62

First, let's write it in the slope-intercept form .In general, slope-intercept form is                                    y=mx + b

where m is the slope

So, writing the equation in the form, we get

                                    ⇒-7y = 62-4x

                                        ⇒7y = 4x-62

                                          ⇒y = 4x/7-62/7

Now, matching the equation with the general form,

                                          m = 4/7

Hence, the slope of the line represented by 4x-7y=62 is 4/7.

Answer:

Z = 0.75x + 0.25y

Step-by-step explanation:

Two bear types are identified :

Black bears and Grizzly bears

9 out of 12 = black bears ; Hence, 3 are grizzled

For the model:

For a bear population of Number x

Total bear population = black bear, x + grizzled bear, y

Proportion of black bear = 9/ 12 = 0.75

Grizzled bear = 1 - 0.75 = 0.25

Total bear population , Z= 0.75x + 0.25y
