Answer 1

So , the percentage of time spent on messenger work by the clerk during the week was most nearly is 16%.

How to find percentage?

From the Latin word "per centum," which meaning "by the hundred," the word "percentage" was borrowed. The denominator of percent's is 100, making them fractions. In other words, it is the relationship between a component and a whole in which the value of the entire is consistently set to 100. The value of the entire is always 100 in a percentage, which is a ratio or fraction. Sam, for instance, would have received a score of 30 out of 100 on his arithmetic test if he received a 30%. When expressed as a ratio, it is written as 030:10 and as a fraction, 30/100. An quantity or part that is contained in each hundred is known as a percentage. The symbol "%" signifies that it is a fraction with 100 as the denominator.

35 h * 1 / 5 = 7 h

35 h * 1 / 2 = 17.5 h

35 h * 1 / 7 = 5 h

7 h + 17.5 h + 5 h

= 29.5 h

The rest of his time = 35 - 29.5

= 5.5 h

5.5 / 35 = 0.15714

= 15 .714 %

Enter your answer in the box.

Answers

The slope of the line passing through (0, 5) and (-12, 2) will be 1/4.

What is Slope?

A slope of a line is a number that describes both the direction and the steepness of the line.

Given that;

Two points on line are (0, 5) and (-12, 2).

Now, The slope of the line passing through (0, 5) and (-12, 2) are calculated as;

m = (2 - 5)/ (-12 - 0)

m = - 3 / -12

m = 3 / 12

m = 1/4

Thus, The slope of the line passing through (0, 5) and (-12, 2) will be 1/4.

Explanation:

Here, we want to get the amount of money Eric earns per week

Let the amount earned be n

Now, to get the value earned, we have to subtract the value he had before from what he has now or simply add what he had before to what he earned now and equate to his total balance now

The given equation is,

2 - b) 2a + b - 2c.

3 - a) 5q + 7.

3 - b) 6r + 3s + 7t.

How to simplify an expression?

An expression is simplified combining the like terms, that is, adding or subtracting, depending on the signal, the terms that have the same variable and the same exponent.

For item 1, the variables are common for all terms, hence we just add the terms keeping the variable, hence:

4g + 6g + g = 11g.4m - m = 3m.5k² - 4k² - 2k² = -k².

For item 2, there are multiple variables, hence we combine the terms of each variable(we cannot add terms with x and y, for example), as follows:

5x + 3x + 5y + 6y = 8x + 11y.2a + 4b + 6c - 3b - 8c = 2a + b - 2c.

Item 3 works similarly to item 2, as there are multiple variables, hence we combine the terms with each variable(or with the constant = no variable), as follows:

9q - 4q + 15 - 8 = 5q + 7.8r + 2s + 4t - 2r + s + 3t = 6r + 3s + 7t.

Answers

The patient's systolic blood pressure will be lowered by 48.709< m<56.091 at a 98% confidence interval.

What is a confidence interval?

For an unknown parameter, a confidence interval is just a range of guess. Usually 95% confidence level is generally the most usual, but other levels, such 90% or 99%, are occasionally used to generate a Confidence interval.

The reduction in systolic blood pressure is, mean, x=52.4

Sample size, n=25

Standard deviation, s=8.5

We must determine the t value for a 90% Confidence interval because the sigma is unknown.

From Inverse t Distribution Calculator, the Confidence interval is 0.98 and the degree of freedom is 25-1=24:

One-sided t-Score: 2.1715

We can now determine the standard error E:

E=2.1715(8.5/√25)=3.691

We can now create the confidence interval by:

x - E < m < x+ E

52.4-3.691< m<52.4+3.691

48.709< m <56.091

The patient's systolic blood pressure will be lowered by 48.709< m <56.091 at a 98% confidence interval.

Given f of x is equal to the quantity x plus 3 end quantity over the quantity x squared minus 4 times x minus 21 end quantity and g(x) = log4x, evaluate (g – f)(8).

Answers

The numeric value of the subtraction function at x = 8 is given by:

(g - f)(8) = 0.5.

How to find the numeric value of a function or of an expression?

To find the numeric value of a function or of an expression, we replace each instance of the input variable in the function by the desired value.

To find the subtraction function, we find the numeric value of each function, then subtract them, as follows:

(g - f)(8) = g(8) - f(8).

Function f(x) is defined as follows:

f(x) = (x + 3)/(x² - 4x - 21).


At x = 8, the numeric value is given as follows:

f(8) = (8 + 3)/(8² - 4(8) - 21) = 11/11 = 1.

Function g(x) is defined as follows:

g(x) = log4(x).

At x = 8, the numeric value is given as follows:

g(8) = log4(8) = 1.5, as 4^(1.5) = 8.

Hence the numeric value of the subtraction function is given by:

(g - f)(8) = g(8) - f(8) = 1.5 - 1 = 0.5.

Answers

Answer:

Step-by-step explanation:

Check image below for explanation

If .5 gallon covers 200

and Susan needs 246.75

1 whole gallons covers 400 (too much)

.5 gallon = 200 paint

?? gallon = 46.75 paint

200 / 46.75 = 4.27807487

.5 / 4.27807487 = 2.13903744

2.13903744 gallon = 46.75 paint

So,

.5 gallon+ 2.13903744 gallon = 2.63903744 gallons

(200 paint + 46.75 paint = 246.75 paint)
