How many different 2-digit ID numbers can be made if each ID number can use the numbers 1 through 8 and no digits may be repeated?

Answers

Answer 1

Answer:1,2,5,7,8 and 9. Thus, we have 6 numbers.

Step-by-step explanation:Then we want to form two-digit numbers without repetition. There are 6 number that is possible to occupy first digit, right? 1,2,5,7,8 or 9. Because it’s without repetition, so the number that have been filled the first digit cannot be the second digit. Thus, the numbers that possible to occupy second place are 5 digits.So step by step

What is another way that you could write the ratio of pennies to quarters?

Answers

Answer:

1/100 to 25/100

or

0.01 to 0.25

Step-by-step explanation:

Pennies are also known as one per cent. Cent refers to 100 and pennies are called one per cent because they value 1 out of 100. 100 pennies equal one dollar.

Similarly, one quarter is 1/4 of a dollar and 1/4 equals 25/100 when multiplying the numerator and denominator by 25.

A quadratic function has one zero (x-intercept) at x = -5 and another zero at x = 3. What is the equation of the axis of symmetry of this function?

Answers

Answer:

x = - 1

Step-by-step explanation:

The axis of symmetry is a vertical line located at the midpoint of the zeros.

Equation is then

x = [tex]\frac{-5+3}{2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , that is x = - 1

In a park, a sidewalk is built around the edge of a circular garden as shown. The sidewalk is 5 feet wide, and the garden measures 10 feet across. Which measurement is closest to the circumference of the outer edge of the sidewalk?

Answers

Answer:

63 feet.

Step-by-step explanation:

The total diameter of the circular garden is given by 5ft+ 10 ft + 5 ft= 20 feet

As the circumference of the circle = 2πr where r = radius obtained by dividing the diameter by 2. Here the diameter = 20 feet and r= d/2 = 20/2 = 10 feet

Putting the values in the circumference formula

Then C= 2(22/7) (10)= 62.85 feet

Rounding gives almost 63 feet .

means as a multiple of the MAD?

The difference of the means is.......? times the MAD


HELP!

Answers

Answer:

The difference of the means is 2 times the MAD

Step-by-step explanation:

Mean of data set A = 42

Mean of data set B = 47

MAD of both data sets = 2.5

Difference of their means = 47 - 42 = 5

Thus, the difference of their means = 2 × the MAD

= 2 × 2.5 = 5

Therefore:

The difference of the means is 2 times the MAD

Assume that θ is an acute angle in a right triangle satisfying the given conditions. Evaluate the 5 remaining trigonometric functions. Sketch a triangle in the correct quadrant and label.

sec θ= 17/15
sin θ<0

Answers

Answer: See step by step. Replace the x with theta

Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.

We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.

We can find tangent by using the identity

[tex]tan^{2} (x)+ 1=sec^{2} (x)[/tex] where x is theta.

[tex]tan^{2} (x)+1=\frac{289}{225}[/tex]

[tex]tan^{2} (x)+\frac{225}{225} =\frac{289}{225}[/tex]

[tex]tan^{2}(x)=\frac{64}{225}[/tex]

tan x=[tex]\frac{8}{15}[/tex], Tangent in the fourth  quadrant is negative  so  the answer is instead

[tex]tan x= -\frac{8}{15}[/tex]

We can find cotangent by taking the recipocial of tan so

[tex]cot=-\frac{15}{8}[/tex]

We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is

[tex]cos =\frac{15}{17}[/tex]

We can find sin by doing quoteint identies.

[tex]\frac{sin x}{cos x} =tan x[/tex]

[tex]\frac{ sin x}{15/17} =-\frac{8}{15}[/tex]

[tex]sin x= -\frac{8}{17}[/tex]

To find csc, take reciprocal of sine.

[tex]csc=\frac{-17}{8}[/tex]

Juanita is bringing the snacks for her daughter’s soccer team. Each girl on the team will eat 1/3 of an orange and drink one serving of juice or 1/9 of the amount in a bottle. How many oranges and how many juice bottles will she need for all 18 girls?show you work!!

Answers

Answer:

6 Oranges and 2 bottles of juice.

Step-by-step explanation:

For the amount of oranges: 18÷3=6 (take 1/3 of 18).

For the bottles of of Juice: 18÷9=2 (take 1/9 of 18).

in this question, if the numerator is 1, then just divide the number of girls by the denominator (eg. 3 and 9 in this case).

There are six oranges and two bottles of juice will she needs for all 18 girls.

What is the division operation?

In mathematics, divides left-hand operands into right-hand operands in the division operation.

For example 4/2 = 2

There are the total number of girls is 18. Each girl will eat 1/3 of an orange and one serving of juice, or 1/9 of the amount in a bottle.

To determine the number of oranges and the bottles of juice.

We have to divide the number of girls by the denominator (eg. 3 and 9 in this case).

For the number of oranges:

1/3 of 18

18 ÷ 3

18 / 3 = 6

For the bottles of Juice:

1/9 of 18

18 ÷ 9

18 / 9 = 2

Hence, there are six oranges and two bottles of juice will she needs for all 18 girls.
