How do you calculate angles on a straight line??

dimaraw [331]

Answer:

Step-by-step explanation:

Straight line is an angle whose vertex point(O) has a value of 180. The arms (OA & OB) of the straight line angle lies opposite to each other from the vertex point

Sum of all the angles in a straight line = 180

From this you can find the value of unknown angle, if other angles are given.

∠AOC + ∠BOC = 180

Tina is saving to buy a notebook computer. She has two options. The first option is to put $200 away initially and save $10 ever

Mamont248 [21]

Answer: In five months,she will save the same money which is $250.

Step-by-step explanation:

Using the first statement we can generate the function y=10x + 200 and using the second statement we can also generate the function y = 30x + 100 . Now using the two equations solve for x and y to determine how many months they cost the same.

y = 10x + 200

y = 30x + 100

Substitute the value of x in the first equation into the second equation.

30x + 100= 10x + 200 now solve for x

-100 -100

30x = 10x + 100

-10x -10x

20x = 100

x= 5

This means in five months Tina will save the same amount. Now to find out how much the amount is, plot the value of x into one of the equations and solve for y.

y = 10(5) + 200

y = 50 + 200

y = 250

She will save $250 with either option.

Please help me answer as soon as possible. Thank u very much. Work is due tomorrow.

Firdavs [7]

The answer is 3 11/12 because the last one said RUNNING and it asked how much did he SWIM. Here is the math.

6/12 + 5/12 = 11/12

1+2=3

3 11/12. Hope this helped!

A human gene carries a certain disease from the mother to the child with a probability rate of 34%. That is, there is a 34% chan

eimsori [14]

Answer:

The probability that at least one of the children get the disease from their mother is P=0.7125.

Step-by-step explanation:

This can be modeled as a binomial random variable.

The parameter p=0.34 is the probability of a child being infected, and is constant and independent of the other events.

The parameter n=3 is the number of children (sample size).

Then, we have to calculate the probabilty that at least one of the children get the disease from their mother. That is:

$P(x\geq1)$

The probability of exactly k children being infected can be calculated as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}$

Then, the easiest way to calculate this probability is using the complement: the value of the probability is 1 (or 100%) less the probability that no children gets infected.

$P(x\geq1)=1-P(x=0)\\\\\\P(x=0) = \dbinom{3}{0} p^{0}(1-p)^{3}=1*1*0.2875=0.2875\\\\\\P(x\geq1)=1-0.2875=0.7125$
