Factor & solve please helppp my brain is mush i don’t remember anything
yanalaym [24]
This equation uses y and x so it cannot be factorised.

Let’s try the equation y^2 - 12y + 36 = 0

Look for two factors of 36 that add to -12.
This would be -6 and -6

(y - 6)(y - 6) = 0
(y - 6) must equal 0
y = 6

Algebra 2, how do you solve these questions?
adelina 88 [10]
#13:

s² = 144
√(s²) = √144
|s| = 12

s = -12 OR s = 12

--------------------

#15 (not sure what letter you used so I went with 'g')

(g-6)² = 25
√[(g-6)²] = √25
|g-6| = 5

g - 6 = -5 OR g - 6 = 5

g = 1 OR g = 11

Tickets to Dundee crowns mr.dchs are $3 for students and $5 for adults. The number of adult tickets sold was 195 more than the n
Maurinko [17]

Answer: number of tickets sold to adult = 566

Step-by-step explanation:

Let x = number of tickets sold by DCHS to students.

Let y = number of tickets sold DCHS to adults.

Tickets to Dundee crowns mr.dchs are $3 for students and $5 for adults.

This means cost of total tickets sold to students and adults is $3x and $5y respectively.

If DCHS collected $3943 for the tickets, then we have

3x + 5y = 3943 - - - - - -1

The number of adult tickets sold was 195 more than the number of student tickets. This means

y = x +195.

Put y = x +195 in equation 1

3x + 5(x+195) = 3943

3x + 5x + 975= 3943

8x +975=3943

8x = 3943-975= 2968

x = 2968/8 = 371

y = 371 + 195= 566

Flip a coin 10 times and record the observed number of heads and tails. For example, with 10 flips one might get 6 heads and 4 t
zepelin [54]

Answer:

The greater the sample size the better is the estimation. A large sample leads to a more accurate result.

Step-by-step explanation:

Consider the table representing the number of heads and tails for all the number of tosses:

Number of tosses    n (HEADS)        n (TAILS)            Ratio

            10                         3                      7                    3 : 7

           30                         14                    16                   7 : 8

          100                        60                   40                  3 : 2

Compute probability of heads for the tosses as follows:

  • n = 10 tosses

        P(\text{HEADS})=\frac{3}{10}=0.30

The probability of heads in case of 10 tosses of a coin is -0.20 away from 50/50.

  • n = 30 tosses

        P(\text{HEADS})=\frac{14}{30}=0.467

The probability of heads in case of 30 tosses of a coin is -0.033 away from 50/50.

  • n = 100 tosses

        P(\text{HEADS})=\frac{60}{100}=0.60

The probability of heads in case of 100 tosses of a coin is 0.10 away from 50/50.

As it can be seen from the above explanation, that as the sample size is increasing the distance between the expected and observed proportion is decreasing.

This happens because, the greater the sample size the better is the estimation. A large sample leads to a more accurate result.
