vodka [1.7K]3 years ago
3 0

Answer:

(13)

<u>x= 8</u>

<u>y=11</u>

(14)

<u>x= 20</u>

<u>y=20.75</u>

(15)

<u>x=9</u>

<u>y=13</u>

Step-by-step explanation:

(13) 8x-1 = 11x -25

24=3x

<u>x= 8</u>

8(8)-1 +15y-48= 180

15y=165

<u>y=11</u>

(14) 7x-44 + 4x + 4= 180

11x= 220

<u>x= 20</u>

4(20)+4+39= 8y-43

123=8y-43

166=8y

<u>y=20.75</u>

(15) 12x+1=15x-26

3x=27

<u>x=9</u>

28+15(9)-26+4y-9=180

4y=52

<u>y=13</u>

Which of the following scenarios MUST represent two independent events?
egoroff_w [7]

Answer: C) P(blue) = 70%, P(green) = 30%, P(blue and green) = 21%

Step-by-step explanation:

Given probabilities P(A) AND P(B) are independent, the probability that both events to occur is given by:

P(A)∩P(B)

thus from the example, independent events will be:

P(blue)=70%, P(green)=30%, P(blue and green)=21%

Because:

P(blue)∩P(green)=0.7×0.3=0.21=21%

natita [175]

Equation for this problem:            Total 3 cubed / (L x W)

So 18.5cm x 15cm = 277.5 is the product of L and W. Now you need to devide the total by 277.5 which is 14. So the aquarium is 14 cm deep.

35 – 2.4 ( 7 – 5)<br> Show each step
saveliy_v [14]

Answer:

35 - 2.4(7-5)

= (35/1)-(24/10)(7-5)

= [(35×10)/(1×10)]-(24/10)(2)

= (350/10)-(24/10)(2)

= (350-24)/10(2)

= 326/10(2)

= 32.6(2)

= 65.2

Thank you.
