Answer:

$4.70

Step-by-step explanation:

First, you need to divide 18.80 by 8.

18.80/8 = 2.35

2.35 is the unit price for one (1) pound bag of flour,

Multiply by 2 to find the price of a two (2) pound bag.

2.35 * 2 = 4.7

$4.70 is the price of a two-pound bag.

hope this helps :)

Let the price be x

Price is $17 now

Answer:

B. 8

Step-by-step explanation:

Explanation: 2.3x3.6 is 8.28, and we round down to 8 because 8.28 is closer to 8 than 9.

Answer:

A: y= 3x-4

B: y= -2/4x+3

Step-by-step explanation:

slope intercept form: y=mx+b

m = slope

slope = rise/run

b = y-intercept

Answer:

A: y = 3x - 4

B: y = -1/2x +3

Step-by-step explanation:

First, lets find the slope of line B. We need to find two coordinates on the line that coincide with points on the grid. We see that (2, 2) and (4, 1) are two points that match the criteria, so we can use both points. You can use any two points, I just randomly chose these two. Slope is nothing but the Y coordinate of the first point  subtracted from the Y coordinate of the second point. We do 2 - 4 and get -2. Next, we do the same thing but with the X coordinates to get 2 - 1, which is 1. We do 1 over -2 to get negative 1/2 for our slope. The last variable in the equation is just where the line hits the Y axis, which is 3. So, the final equation is y = -1/2x + 3. Rinse and repeat for the next question.

Step-by-step explanation:

There are 4 possibilities for the first card. After that, there are 3 possibilities for the second card. Finally, there are 2 possibilities for the third card. The total number of permutations is 4×3×2 = 24. Here's the list (in alphabetical order): ARS ART ASR AST ATR ATS RAS RAT RSA RST RTA RTS SAR SAT SRA SRT STA STR TAR TAS TRA TRS TSA TSR

Step-by-step explanation:

The Pythagorean Theorem is a useful tool that shows how the sum of the areas of three intersecting squares can determine the side lengths of a right triangle.

You use the Pythagorean Theorem when you know the lengths of two sides of a right triangle and you want to figure out the length of the third side.

C

Line symmetry is when a shape can be folded over an imaginary axis and have both sides be a mirror of the other. This axis is called the line of symmetry.

Letter C

In this case, if you draw a horizontal line across the middle of the letter "C" and fold the letter, each half would be the same. The top half of "C" mirrors the lower half.

Other Examples

The lowercase letter "l" also has 2 lines of symmetry. You can draw both a horizontal and vertical line across the letter and each side will mirror the other.

In Rectangle , 16 copies of ABCD fit inside A'B'C'D'.

What is a rectangle, exactly?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral.

                                       The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.

DA = 3

D'A' = 12

Scale factor DA/D'A' = 3/12 = 1/4

The scale factor = 1/4

The scale factor = 1/4

The probability (x s 110) is 0.975, the correct option is A.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

We are given that;

Mean=98

Now,

To find the probability that x is less than or equal to 110 for a normal distribution with mean 98 and standard deviation 6, we need to use the standard normal table or a calculator.

Using the standard normal table, we first need to convert x to a z-score using the formula:

z = (x - mean) / standard deviation

Plugging in x = 110, mean = 98 and standard deviation = 6, we get:

z = (110 - 98) / 6

z = 2

This means that x = 110 is equivalent to z = 2 on the standard normal distribution.

Now we look up the value of z = 2 on the table and find that it corresponds to an area of 0.9772. This means that P(z ≤ 2) = 0.9772.

However, this is not the answer we want. We want P(x ≤ 110), which is the same as P(z ≤ 2). The table gives us the area to the left of z, but we need to subtract it from 1 to get the area to the right of z. This is because P(x ≤ 110) = P(z ≤ 2) + P(z > 2) = 1.

Therefore,

P(x ≤ 110) = P(z ≤ 2)

P(x ≤ 110) = 1 - P(z > 2)

P(x ≤ 110) = 1 - (1 - P(z ≤ 2))

P(x ≤ 110) = P(z ≤ 2)

P(x ≤ 110) ≈0.9772

Therefore, by the given mean the answer will be 0.975.

The equation that is equivalent to the considered equation of log is given by: Option E: 2^3 = x+5

When you raise a number with an exponent, there comes a result.

Lets say you get [tex]a^b = c[/tex]

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

[tex]b = \log_a(c)[/tex]

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Some properties of logarithm are:

[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) \times log_b(c) = \log_a(c)[/tex]

Log with base e = 2.71828... is written as [tex]\ln(x)[/tex] simply.

Log with base 10 is written as [tex]\log(x)[/tex] simply.

The equation given is:

[tex]\log_3(x+5) = 2[/tex]

By using the definition of log, which says [tex]a^b = c \leftrightarrow \log_a(c) = b[/tex], we get:

[tex](x+5) = 2^3[/tex] or [tex]2^3 = x+5[/tex]

Thus, the equation that is equivalent to the considered equation of log is given by: Option E: [tex]2^3 = x+5[/tex]

(we used the fact that the question is asked in a way that expresses that there is only one equivalent equation. Plus we used the fact that as option E is a sure equivalent version, so it is correct option).

Thus, the equation that is equivalent to the considered equation of log is given by: Option E: [tex]2^3 = x+5[/tex]
