Please help my sister with this

Mathematics
1 answer:
Arturiano [62]3 years ago
7 0
Hello there!

The (main) thing that you would want to remember would be that, 0.4 is .4 of 1. So, when looking at your options, we would want to find something that is pretty much almost half of 1.

For example: 0.5 is half 1, so in this case, 0.4 is almost half of 1, and we would want to find an option that would be very similar.

Your correct answer would be (option b and option c).

They both are 0.4 to 1.

Which in this case 40 to 100. Or even, 4 to 10.

Your correct answer would be (option b and c).

I hope this helps you!

150 decreased by 60%

Hello there the answer to your question would be 60. Since 150-(60%*150) = 150 - 60 *150 = (1-60%)*150 = (100%-60%) * 150= 40% * 150 = 40/100 * 150 = 40 * 150 ÷ 100 = 6000/100 = 60. Hope this helps you out, have a great day!

Which of the following are based on empirical probability
Vikentia [17]

The empirical probability is Life insurance, Car insurance, and Mortality.

<h3>What is empirical probability?</h3>

The ratio of the number of outcomes in which a defined event occurs to the total number of trials, not in a theoretical sample space but in a real experiment, is the empirical probability, relative frequency, or experimental probability of an event.

Therefore the empirical probability will be Life insurance, Car insurance, and Mortality.

A flag pole has a rope that attaches to the ground from the top of the flagpole the rope create a 30° angle with the ground and
OLEGan [10]

Answer:

5.77\ \text{m}

11.54\ \text{m}

Step-by-step explanation:

p = Height of pole

h = Length of role

b = Distance between the bottom of the rope and bottom of the pole = 10 m

\theta = Angle between the rope and the ground = 30^{\circ}

\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}

The length of the rope is 5.77\ \text{m}

\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}

The length of the pole is 11.54\ \text{m}
