Answer:

\(x = \frac{11}{c}\) (x = 11/c)

Step-by-step explanation:

cx - 4 = 7

cx = 7 + 4

cx = 11

\(x = \frac{11}{c}\) (x = 11/c)

Hope this helps! :)

Answer:

x=11/c

Step-by-step explanation:

In order to solve for x, we must get x by itself.

cx-4=7

4 is being subtracted from cx. The inverse of subtraction is addition. Add 4 to both sides of the equation.

cx-4+4= 7+4

cx= 7+4

cx= 11

x is being multiplied by c. The inverse of multiplication is division. Divide both sides of the equation by c.

cx/c=11/c

x= 11/c

The equation cx-4=7 solved for x is: x= 11/c

Answer:

0.251

Step-by-step explanation:

for a normal distribution question, we need to use the z-score formula for finding the area (probability).

use the z-score formula to convert the values.

z = (X - υ) / σ

where X is the test statistic, υ is the mean, σ is the standard deviation.

z = (4 - 5) / 1.5

= -0.67

in the z-table, find -0.6 down the side column and 0.07 on the top row. the number in the table where these two meet is 0.25143. this is the area to the left of z = -0.67. this is what we want for this question since we want an orange that weighs less than 4oz.

that means that the probability is 0.251 to nearest thousandth

There are several types of statistical evaluations that help to sort out the true significance of clinical research findings. These include effect size analyses, significance testing, confidence intervals, and meta-analysis.

Statistical evaluations are methods that provide essential information to guide clinical decision-making, treatment, and future research. There are many different types of statistical evaluations used to sort out the true significance of clinical research findings. Types of statistical evaluations that help to sort out the true significance of clinical research findings:

Effect size analyses: These analyses provide an indication of the strength and size of the effect that an intervention had on the outcome. This is typically represented as a standardized measure, such as Cohen's d or Hedges' g, which allows for comparison across studies.

Significance testing: Significance testing involves comparing the observed data to what would be expected under the null hypothesis (e.g., no effect). If the observed data are unlikely to have occurred by chance, then the null hypothesis is rejected and the results are considered statistically significant.

Confidence intervals: A confidence interval is a range of values within which the true population value is estimated to lie with a certain degree of certainty. This provides a measure of the precision of the estimated effect size.

Meta-analysis: Meta-analysis is a statistical method used to synthesize the results of multiple studies to provide a more precise estimate of the effect size. It is often used to answer questions that cannot be answered by a single study, such as the effectiveness of an intervention in different populations or settings.

Answer: The percentage of the original price was his discount = 10%

Step-by-step explanation:

Given: original price = $60

Price after discount =  $54

Discount = Price after discount  - original price

= $ (60-54) = $6

The percentage of the original price was his discount = \(\dfrac{Discount}{Original\ price}\times100\)

\(=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%\)

Hence, the percentage of the original price was his discount = 10%

In this nation, there are 26 million possible basic licence plates.

A nation's typical automotive number plates typically consist of 1 number, 2 letters and 4 numerals in that order. We employ the following approach to determine how many alternative standard plates are feasible in this nation:

The first number can be represented by any one of ten digits, from 0 to 9. The two letters have a total of 26 potential combinations, assuming that the letters are not case-sensitive. Finally, each of the remaining four integers has a possible set of 10 digits. By combining all of these potential combinations together, the total number of various standard plates that can be used in this country is determined.

In this case, the total number of different standard plates that are possible in this country can be calculated as follows: 10 × 26 × 10 × 10 × 10 × 10 = 26,000,000.

By using Pythagoras theorem, the distance between the two complex function is 12.65 meters

The distance or length can be calculated by using Pythagoras theorem.

To find the distance using the modulus of the difference between

z 1 = -8 + 3i and z 2 = 4 + 7i, let us first find the difference.

Z2 - Z1 = (4 - (-8)) + (7 - 3)i

Z2 - Z1 = 12 + 4i

Where x = 12 and y = 4

|r| = √(x² + y²)

| r | = √(12² + 4²)

| r | = √160

| r | = 12.65 m

Answer: 4 inches by 6 inches or 8 inches by 3 inches.

Step-by-step explanation:

The area of a rectangle is A = W*L

where L is the width and L is the lenght.

Now, the original rectangle has a measure of 8 in by 6 in.

if 8in is the lenght and 6 in is the width.

We want to divide only one of those measures in equal parts, such that when we take the product of the end results is equal to 24 in.

If we divide the lenght by half (so both parts will have the same width as this did not change), we now have that the lenght is 8in/2 = 4in and the width is 6in.

Now the area is 4in*6in = 24in, which is the area that we where looking for.

We also could cut the width in half, and get the dimensions 8 inches by 3 inches.

The expression 1/2(2a + 1)(a + 3) can be described as the product of two expressions as 1/2 and (2a + 1)(a + 3).

The entire expression is the product of two smaller expressions, namely 1/2 and (2a + 1)(a + 3).

The second expression, (2a + 1)(a + 3), is a product of two binomials. Each binomial contains two terms separated by a plus sign.

The first binomial, 2a + 1, has a coefficient of 2 in front of the variable a and a constant term of 1. The second binomial, a + 3, has a coefficient of 1 in front of the variable a and a constant term of 3.

To simplify the expression 1/2(2a + 1)(a + 3), we can distribute the 1/2 to both terms inside the parentheses, resulting in the expression (a+1/2)(a+3).

The expression can be further simplified by multiplying the two binomials together, resulting in the quadratic expression a² + 7/2a + 3/2.

The value of x in the chord intersection is 16 units.

The intersecting chord theorem  states that the products of the lengths of the line segments on each chord are equal. In other words, If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.

Therefore, lets find the value of x in the intersecting chords as follows:

15 × x = 24 × 10

15x = 240

divide both sides of the equation by 15

x = 240 / 15
