Answer:

66.666%

Step-by-step explanation:

Ok first of all the first ticket is $3.00 the second one is 5.00. Important to note that the difference is $2.00. So we do $2.00/$3.00 which gives the answer of 66.666(recurring). Therefore your answer is 66.666%

0

The answer would be 0 because 2/3 wouldn't be able to round up to a number so it would be 0.But if what you are saying is 3 1/3 rounded to the nearest whole number it would be 3

Answer:

a)

Step-by-step explanation:

for each point (A, B, C) reduce the 'x-value' by two and reduce the 'y-value' by 7

for example, for point A:

to find A':  (-6, -7) would be (-6-2, -7-7)  which is (-8, -14)

Answer:

x = 19

Step-by-step explanation:

The 5x + 30 should also = 125, since they both have the same angle.

So you can make this equation:

125 = 5x + 30

125 - 30 = 5x

95/5 = x

x = 19

Step-by-step explanation:

125°=5x+30°

125-30= 95

95÷5=19

so x = 19

Answer:

A, because with all of the X values they can be multiplied to get to the y value.

Step-by-step explanation:

a) 0.04>0.004 is right.

b) 8.2>8.02 is right.

c) 7.6<7.67 is right

d) 0.03>0.003 is right.

Answer:

Area of parallelogram is =base *height

Given area of parallogram is 315square inches

Therefore, area of parallogram =b*h

Therefore area of parallogram =21*h

Therefore, 315=21*h

Therefore 315/21=h

Therefore, 15 =height

Height of parallogram is 15 inches

Answer:

The price of the TV with the sales tax included is $ 722.38.

Step-by-step explanation:

Given that a TV has a listed price of $ 671.98 before tax, and the sales tax rate is 7.5%, to find the total cost of the TV with sales tax included the following calculation must be performed:

671.98 + (671.98 x 0.075) = X

671.98 + 50.3985 = X

722.3785 = X

Therefore, the price of the TV with the sales tax included is $ 722.38.

Answer:

C

Step-by-step explanation:

The percentage of the shaded region of the circle is 75%.

Option C is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The circle can be in 4 parts.

Three parts are shaded.

Now,

The percent of the shaded region.

= (Shaded parts / Total parts) x 100

= 3/4 x 100

= 75%

Thus,

75% is shaded.

Answer:

The critical value that should be used is T = 2.492.

The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³

Step-by-step explanation:

We have the standard deviation for the mean, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 25 - 1 = 24

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.492, which is the critical value that should be used.

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.492\frac{0.0313}{\sqrt{25}} = 0.016[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 0.502 - 0.016 = 0.486 cc/m³

The upper end of the interval is the sample mean added to M. So it is 0.502 + 0.016 = 0.518 cc/m³

The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³
