Answer:

5 bows

Step-by-step explanation:

Total feets of ribbon = 3 1/2

Fraction required to make a bow = 2/3

Number of bows that can be made = (total ribbon / Fraction required to make a bow)

3 1/2 ÷ 2/3

7/2 ÷ 2/3

7/2 * 3/2

= 21 / 4

= 5.25

A coin is tossed 20 times. It lands on heads 9 times. What is the P(H) according to your experiment? Write your answer as a frac

Mama L [17]

Answer:

$\frac{9}{20}=0.45=45$ %

Step-by-step explanation:

Probability is found by first forming a fraction where the numerator represents the number of desired outcomes and the denominator represents the total number of outcomes. In this case, the desired outcomes is the amount of times the coin lands on heads (9) and the total outcomes is the number of times the coin is tossed (20):

$\frac{9}{20}$

Divide numerator by denominator to get a decimal: 9÷20= 0.45

Multiply the decimal by 100 to get a percent: 0.45 x 100 = 45%

Help anyone pleaseeee

Answer:

36 <127

(36,127°)

36 [ cos (127) + i sin (127)]

Step-by-step explanation:

w1 = 2 < 95

w2 = 18 < 32

w1 * w2

We multiply the magnitude and add the angles

w1 * w2 = 2*18 < (95+32)

=36 < 127

36 [ cos (127) + i sin (127)]
