Help! What’s the surface area??

Answer:

1 3/8 yards

Step-by-step explanation:

Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks

The above question is calculated as:

2 3/4 yards × 1/2 of ribbon

= 2 3/4 × 1/2

= 11/4 × 1/2

= 11/8

= 1 3/8 yards

Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks

Answer:

[tex]a_{15} = 2147483648[/tex]

Step-by-step explanation:

first, find the common ratio (r) by dividing the second term by the first term:

r = 32 / 8 = 4

next, write a formula for the geometric sequence:

[tex]a_{n} = a_{1} * (r)^{n-1} \\a_{15} = 8 * (4)^{14} \\a_{15} = 2147483648[/tex]

Answer:

44200 of them were girls

Step-by-step explanation:

If the ratio is 8:25, we must find x:65000

In order to change the ratio 8:25 into x:65000, we must multiply 25 by 2600. So you have to multiply 8 by 2600 too

8 x 2600 = 20800

65000 (total students) - 20800 (boy students) = 44200 (girl students)

1) 31.5

Step-by-step explanation:

tanA = opp/ adj

tanA = 11.2/18.3

A= arctan(11.2/18.3)

A= 31.468   -> 31.5

Answer:

1/24

Step-by-step explanation:

1/24 bc there is 24 students in the class and the teachercould only choose 1 student

The two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl are:

- Assign one gender to even numbers and the other gender to odd numbers.

- Assign each student a number from 1 to 24, and then divide the numbers into two groups.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

To simulate the probability of selecting a boy or girl from Trevor's math class,

We can use a six-sided die in two different ways:

- Assign one gender to even numbers and the other gender to odd numbers.

For example, we can assign boys to even numbers (2, 4, 6) and girls to odd numbers (1, 3, 5).

We would then roll the die, and if it lands on an even number, we would consider the selected student to be a boy, and if it lands on an odd number, we would consider the selected student to be a girl.

We can repeat this process multiple times to simulate the probability of selecting a boy or girl.

- Assign each student a number from 1 to 24, and then divide the numbers into two groups:

one group for boys and the other group for girls.

For example, we can assign the boys the numbers 1 to 12 and the girls the numbers 13 to 24.

We would then roll the die and select the student with the corresponding number.

If the number is between 1 and 12, we would consider the selected student to be a boy, and if the number is between 13 and 24, we would consider the selected student to be a girl.

We can also repeat this process multiple times to simulate the probability of selecting a boy or girl.

Thus,

The two different ways that rolling a six-sided die could be used to simulate the probability that Trevor's teacher will select a boy or girl are:

- Assign one gender to even numbers and the other gender to odd numbers.

- Assign each student a number from 1 to 24, and then divide the numbers into two groups.

Answer:

-4

Step-by-step explanation:

m is the slope

Answer:

m=-4

Step-by-step explanation:

in the formula y=mx, m is the slope. You can find it by looking at the graph, and finding two points that are defined on the grid. In this case, we can use (0,0) and (-1,4). Put it into the slope formula, (y2-y1)/(x2-x1). In this case, it would be (4-0)/(-1-0), which simplifies to 4/-1=-4. Therefore, m= -4

Answer:

2.5

Step-by-step explanation:

2 times 2.5= 5

6 times 2.5= 15

8 times 2.5= 20

So for 1 It will be 2.5

1 times 2.5= 2.5

Answer:

1.53 times

Step-by-step explanation:

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?

We would have:

First strain : Second strain

0.000000143 mm : 0.0000000937 mm

How much larger is the first strain than the second?

We divide both by the length of the second strain

0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937

1.52614727855 times

Approximately = 1.53 times

Answer: Correct answer is C -I just took the test

we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.

you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)

now we have:

g(x) = -f(x) = - 4(1/2)x

then the right answer is the third option:

g(x) = -4(1/2)x

Answer:

58.1 degrees

Step-by-step explanation:

Given the following

JK = 9.4miles (towards south) negative y axis

If the move 15.1 miles towards east (that will be towards the positive x axis)

Using the SOH CAH TOA identity

opposite= 15.1 miles(side facing m<J)

adjacent= JK = 9.4miles

tan theta = opposite/adjacent

tan m<J = 15.1/9.4

tan m<J = 1.6063

m<J = arctan (1.6063)

m<J = 58.09 degrees

Hence the measure of m<J to the nearest tenth is 58.1 degrees

Answer:

We know that our sample is a group of 50 randomly selected students.

First, we want to know the name of the sampling technique.

There are a lot of sampling techniques, but knowing that the students are selected randomly, we can conclude that this is the simple random sampling technique, where each individual is chosen entirely by chance (so all the students have the same probability of being chosen)

Now we want to know if the method is biased or not,

Always that we use the simple random sampling technique, we will have an unbiased sample.
