Answer:

the experimental probability of the spinner’s landing on A is:

17%

Step-by-step explanation:

We are given that:

A spinner has five sections, labeled A, B, C, D, and E. The spinner is spun 84 times, and the results are recorded in the table.

Outcome Number of times outcome occurred

A 14

B 20

C 18

D 15

E 17

We are asked to find  the experimental probability of the spinner’s landing on A

P(landing A)=no. of times outcome A has occurred/total number of outcomes

                  = 14/84

                  = 1/6

                  = 100/6%

                 = 16.66%

                 ≈ 17%

17% because you would do the number of times it landed on section a (14) over the total times spun (84) which gives you 16.6666 (16 2/3) which would round up to 17%. Hope this helps!

You need 3 1/2 cups of flour for each batch of cupcakes. How many whole batches can make if you have 17 cups of flour? Show two
rosijanka [135]

<u>ANSWER:</u>

4 batches of cupcakes can be made.

<u>SOLUTION: </u>

Given, we need 3\frac{1}{2} cups of flour for each batch of cupcakes. And we have 17 cups of flour.

We need to find how many batches can be made.

1st way:

We will get the number of batches when we divide the available cups with cups required for one batch.

Available cups = 17 and required cups for one batch = 3\frac{1}{2} = \frac{7}{2} cups

number of batches = $\frac{17}{\frac{7}{2}}$

$=\frac{17}{1} \times \frac{2}{7}$

$=\frac{34}{7}$ = 4.857

As the number of batches can’t be fraction, we will neglect the fractional part.

2nd way:

Let the number of batches be x.

Then, cups of flour required for batches must be less than available flour

(x)(\frac{7}{2}) < 17

(x)(7) < (2)(17)

7x < 34

x < \frac{34}{7}

x < 4.857

As the number of batches must be an whole number, x becomes 4.

Hence, 4 batches of cupcakes can be made.

Use the given conditional statement to determine the converse and inverse statements. If a line is vertical, then it has undefin
Georgia [21]
1) Definitions:

1.1) Inverse statement: negating the hypothesis and the conclusion of the original statement, i.e.:

conditional statement: p → q

inverse: ~p → ~q (the symbol ~ means the negation)

1.2) Converse statement: switching the hypothesis and the conclusion of the conditional statement, i.e.:

conditional statement: p → q

converse: q → p

2)  converse of the given statement

conditional: <span>If a line is vertical, then it has undefined slope.

converse: switch the hypothesis and the conclusion

if a line has undefined slope, then it is vertical <------- answer

</span>3) Inverse of the given statement

conditional: if <span>a line is vertical, then it has undefined slope.

inverse: negate both hypothesis and conclusion.

 </span>if a line is not vertical, then it does not have an undefined slope <---answer
