Answer:

non-cardholder: 152

cardholder: 147

Step-by-step explanation:

Lets make a system of equations

c=cardholder

n=non-cardholder

1. c + n = 299

2. 1.25c + 2.50n = 563.75

Write 1 as n = 299-c

Write 2 as cents, 125c + 250n = 56375

n= 299-c

125c + 250n = 56375

Substitute n with 299 - c

125c + 250(299-c) = 56375

125c + 74750 - 250c = 56375

74750 - 125c = 56375

125c = 18375

c = 147

n = 299 - c

n = 299 - c = 152

Hope this helps :)

Have a nice day!

24.42

Step-by-step explanation:

Quotient can be defined as the result when a number is divided by another number.

Here, the Dividend = 7.326; Divisor = 0.3

7.326 ÷ 0.3 = 24.42

This shows that 7.326 is not exactly divisible by 0.3

Therefore, quotient = 24.42

The 90% confidence interval for the mean score, μ, of all students taking the test is B. 21.8<u<23.0

Given a=0.1, Z(0.05)=1.645 (from standard normal table)

So 90% confidence interval is

xbar+/-Z*s/vn

= 22.4+/-1.645*2.8/sqrt(66)

= (21.83304, 22.96696)

Therefore, the 90% confidence interval for the mean score, μ, of all students taking the test is 21.8<u<23.0.

The equations which is equivalent to 1 whole 1/2 x 3 whole 1/5 = 4 whole 1/2 is 3/2 x 16/5 = 9/2.

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now given equation is,

1 whole 1/2 x 3 whole 1/5 = 4 whole 1/2

Converting them into simple fraction we get,

1 whole 1/2 = 3/2

3 whole 1/5 = 16/5

4 whole 1/2 = 9/2

Thus, the equation becomes,

3/2 x 16/5 = 9/2

this is the required equivalent equation for the given equation.

The measure of the central angle m∠UQR is 130 degrees.

Central angle is the angle formed by two arms and having the vertex at the centre of a circle.

The diameter of a circle runs from the centre of a circle.

The diameter SU and RT intersect each other at point Q.

Therefore,

m∠UQT = m∠RQS (Vertically opposite angles)

m∠UQR = m∠TQS (Vertically opposite angles)

Hence,

m∠RQS = 50°

Therefore,

m∠UQR = 360 - 50 + 50  / 2

m∠UQR = 360 - 100 / 2

m∠UQR = 260 / 2

m∠UQR = 130°

Therefore, the measure of the central angle m∠UQR is 130 degrees.

Step-by-step explanation:

For the function g(x) we have:

There are multiple features we can find, in this case, the most important ones are:

Domain.

Y-intercept.

Range.

First let's find the domain.

We know that logarithmic functions can be only evaluated in arguments larger than zero, so:

x + 2  > 0

x > -2

The domain is the set of all real numbers larger than -2.

Now the range is trivial, for all logarithmic functions the range is the set of all real numbers.

Finally, for the y-intercept we need to evaluate in x = 0, so we get:

y-intercept = log(0 + 2) = log(2) = 0.3

If 80 % (percentage) of marbles are blue then there are 36 blue marbles.

Percentage is the process of representing parts of a number by dividing the number into equal hundreds.

If the total amount is equivalent to 100 then the percentage denotes the number which is identical to the part of the number. In other words percentage denoted as % is part of 100.

The process of converting a part into percentage is by dividing the part by the total amount and multiplying the result by 100.

Now the total number of marbles in the jar is 45 and 80% of them are blue.

Now let us consider this :

so 80% of 45 = 80/100 × 45

The steps given to find the standard deviation of the data-set are as follows:

For this problem, the are 5 values, hence:

n = 5.

The sum of the values is given by:

6 + 7 + 8 + 9 + 10 = 40.

Hence:

[tex]\sum x = 40[/tex]

The mean is given by:

40/5 = 8.

Hence:

[tex]\bar{x} = \frac{\sum x}{n} = 8[/tex]

The sum of the differences squared between each observation and the mean is:

(6 - 8)² + (7 - 8)² + (8 - 8)² + (9 - 8)² + (10 - 8)² = 10.

Hence:

[tex]\sum (x - \bar{x})^2 = 10[/tex]

Dividing by the number of values, we have that 10/5 = 2, hence:

[tex]\frac{\sum (x - \bar{x})^2}{n} = 2[/tex]
