Seventh grade > EE.11 Probability of independent and dependent events NED
ella [17]

Step-by-step explanation:

each combination of 2 specific numbers has the same probability. there is no difference in probability between the individual numbers.

remember, a probability is always desired cases over all possible cases.

we have 4 different possible outcomes every time we spin the spinner.

to get a specific number has the probability of 1/4, because we want 1 specific outcome, and have in total 4 different possibilities.

now, we spin a second time. the probability to get a specific number is again 1/4.

but, if we consider both events to be connected, when we want to know the probability to get 2 specific numbers when spinning twice, we have to multiply the individual probabilities :

1/4 × 1/4 = 1/16

so, the probability to land first on a 5, and then secondly on a 2 is 1/16.

the same as for landing first on a 3, and then on a 5.

the same as for landing first on a 4, and then on a 4 (again).

that is because the individual spin results are independent. the result of the first spin does not impact in any way the result of the second spin (in contrary to e.g. pulling multiple cards without returning the previously pulled cards).

How do you solve 2/7m -1/7 = 3/14
Mars2501 [29]

the only thing you need to do is separate m:

2/7m= 3/14 + 1/7

2/7m= 5/14

m= (5/14)/(2/7)

m= 5/14 × 7/2

m= 35/28

m= 5/4

Jorge wants to plant 70 total flowers in his new garden.He wants the ratio of tulips to daisies in his garden to be 2 to 5. He d
weeeeeb [17]
Add the ratio together:  2 + 5 = 7
Divide this by the total number of plants;
70/7 = 10

Now times the ration by this number:
2:5 becomes 20:50 (times by 10)
This tells us we have 20 tulips as 50 daisies

i used the butterfly method.

92/75 = x/100.

i multiplied 92*100=9200

then i divided it with 75.

9200/75=x

Express the answer in standard form.​
Natali [406]

Answer:

-2x^{2} +8x-10

Step-by-step explanation:

Standard form is basically where the degrees of the terms are in descending order.

First, let's distribute the negative sign to the terms in the second parentheses:

-(3x^{2} -5x+3) = -3x^{2} +5x-3

Now, we can just combine like terms with the terms from the first parentheses:

x^{2} +3x - 7 - 3x^{2} +5x-3 = -2x^{2} +8x-10

So, our answer is: -2x^{2} +8x-10
