Answer:

743.25m^2

Step-by-step explanation:

Area of triangle = 1/2bh

= 1/2 x 30 x 26

= 390

Area of semi circle = 1/2 πr^2

= 1/ 2 x 3.14 x 15 x15

=353.25m^2

= 390 + 353.25

= 743.25m^2

743.25

Step-by-step explanation:

To find the area of a triangle you use this formula (h= height b=base) A=hb/2 So 26*30/2=390

To find the area of a circle you use this formula (r= radius π=3.14) A=πr^2 So 3.14*15^2=706.5 Now cut it in half because it's a half circle 706.5/2=353.25

Add them 353.25+390= 743.25

Answer:

b. 0.45.

Step-by-step explanation:

The total possible outcome of a probability is 1

Given;

Probability that both lights will be red when she reaches them = 0.22

Probability that the first light will be red and the second light will not be red = 0.33

Probability that the second light will be red when she reaches it = x

These are all the possible outcomes, therefore

0.22 + 0.33 + x = 1

0.55 + x = 1

x = 1 - 0.55

x = 0.45

Option b

ASAP HELP: If a sample proportion is 0.55, which range of possible values best describes an estimate for the population paramete

iris [78.8K]

Answer:

B.(0.4,0.7)

Step-by-step explanation:

We are given that

Sample proportion

$\hat{p}=0.55$

We have to find the range of possible values which describes best an estimate for the population parameter.

Estimate for the population parameter

$\hat{p}\pm Z(SE)$

A.(0.55,0.6)

Difference between 0.55 and 0.55=0

Difference between 0.55 and 0.6=0.05

Difference between 0.55 and 0.55 is not equal to difference between 0.55 and 0.6.

Hence, option A is wrong.

B.(0.4,0.7)

Difference between 0.55 and 0.4=0.15

Difference between 0.55 and 0.7=0.15

Difference between 0.55 and 0.4 is equal to difference between 0.55 and 0.7.

Hence, option B is correct.

C. (0.4,0.69)

Difference between 0.55 and 0.4=0.15

Difference between 0.55 and 0.69=0.14

Difference between 0.55 and 0.4 is not equal to difference between 0.55 and 0.69.

Hence, option C is not correct.

D.(0.5,0.59)

Difference between 0.55 and 0.5=0.05

Difference between 0.55 and 0.59=0.04

Difference between 0.55 and 0.5 is not equal to difference between 0.55 and 0.59.

Hence, option D is not correct.

Plz help in the picture below plz ill give you brainliestt

nexus9112 [7]

change both the fractions to improper fractions. the area will be 147/4 , and the width will be 9/2 . with both of these you may now divide, (147/4) / (9/2)

remember to use the KCF when dividing fractions.

147 * 2 = 294

4 * 9 = 36

your new fraction will be 294/36 .... which it is also 8 1/6
