A child gets 20 heads out of 30 tosses of a coin. If he declared the chance of getting a head with that coin were 2/3, that woul

Komok [63]

Answer: Experimental probability

Step-by-step explanation:

There are two kinds of probability: Theoretical probability and Experimental probability.

To calculate theoretical probability we divide favorable outcomes by total outcomes.

To calculate experimental probability we divide number of times an event occurs by the total number of trials or times the activity is performed.

Here, A child gets 20 heads out of 30 tosses of a coin. If he declared the chance of getting a head with that coin were 2/3, which is dependent on the activity he performed, thus it is an experimental probability.

If K parallel to L find the value of a and the value of b.

CaHeK987 [17]

Answer:

$a = 30$

$b = 40$

Step-by-step explanation:

Given

The attached triangle

Such that K is parallel to L

Required

Find the value of a and b

From the properties of parallel triangles;

Provided that k is parallel to l, then

$\frac{a}{40} = \frac{a+15}{60}$

Multiply both sides by (60)(40)

$(60)*(40)*\frac{a}{40} = (60)*(40)*\frac{a+15}{60}$

$60a = 40(a+15)$

Open Bracket

$60a = 40*a+40*15$

$60a = 40a+600$

Subtract 40a from both sides

$60a - 40a = 40a - 40a + 600$

$20a = 600$

Divide both sides by 20

$\frac{20a}{20} = \frac{600}{20}$

$a = \frac{600}{20}$

$a = 30$

Similarly;

$\frac{b}{40} = \frac{b+20}{60}$

Multiply both sides by (60)(40)

$(60)*(40)*\frac{b}{40} = (60)*(40)*\frac{b+20}{60}$

$60b = 40(b+20)$

Open Bracket

$60b = 40*b+40*20$

$60b = 40b+800$

Subtract 40b from both sides

$60b - 40b= 40b - 40b + 800$

$20b= 800$

Divide both sides by 20

$\frac{20b}{20} = \frac{800}{20}$

$b = \frac{800}{20}$

$b = 40$

Tyler’s cell phone plan costs $350 to start, then there is a $50 charge each month. on the same grid as Hana plan, graph the cos

yaroslaw [1]

Based on the graphs representing Tyler and Hana's cell phone plans, we can say that:

They are similar because their slopes are the same.
They are different because their y-intercepts are different.

<h3>How are the graphs related?</h3>

Hana's plan has a $50 monthly charge which is the same as Tyler's. This means that Tyler and Hana's graph will have the same slope because their total amounts are changing by the same amount.

Tyler's y-intercept would be $350 which was the starting point of his plan and Hana's y-intercept would be $250. Their intercepts would therefore be different.

Rest of the question is:

Hana's cell phone plan costs $200 to start. Then there is a $50 charge each month.
