3 0

Answer:

\frac{18}{19}

Step-by-step explanation:

The absolute value of a number is how far away it is from 0 on the number line. Even though \frac{-18}{19} is a negative number, the absolute value wouldn't be \frac{-18}{19}, because distance can't be negative. Hence the absolute value of \frac{-18}{19} is \frac{18}{19}.

Which would you consider to be more accurate, a probability experiment of 10 trials or a probability experiment of 100 trials
Marat540 [252]
I would 100 because the more the trials means the more the results which means you get more of an accurate experiment then if you only did 10. Because since you have so many answers from all of the experiments you can conclude the correct answer from all of the experiments. I hope you get what I’m trying to say

9. Use the rule of multiplication to calculate the probability that a particular F2 individual will be homozygous recessive or d
Bess [88]

Answer:

Complete: (1/2 dominant. + 1/2 recessive.)2

Homozygous. recessive.: 1/2 recessive. x 1/2 rec. = 1/4 rec.-rec.

Homozygous. dominant.: 1/2 dominant. x 1/2 dominant. = 1/4 dom.-dom.

Step-by-step explanation:

First, let us understand what the rule of multiplication is all about:

Basically, the rule of multiplication is a rule that states that there is a probability that two independent parallel event will eventually meet at a point.

Referring back to the question and applying the rule of multiplication,

we have,

Complete: (1/2 dominant + 1/2 recessive.) 2

Homozygous. recessive.: 1/2 rec. x 1/2 rec. = 1/4 recessive.-rec.

Homozygous. dominant.: 1/2 dom. x 1/2 dom. = 1/4 dom.-dom.

Solve by factoring 2x squared -6 = x squared+48
Kitty [74]

x = ± 3√6

2x² - 6 = x² + 48 ( subtract x² from both sides )

x² - 6 = 48 ( add 6 to both sides )

x² = 54 ( take the square root of both sides )

x = ± √54 = ± 3√6

Item 14<br> Find the missing dimension. Use the scale factor 1 : 12.
Vitek1552 [10]

Answer:

3.84m

Step-by-step explanation:

If the scale for this Water tower is 1 : 12 then this means that for every 1cm of the model, the actual water tower has 12cm. Therefore, in order to find the actual depth of the water tower we first need to multiply the depth of the model by 12.

32cm * 12 = 384cm

1 cm is equal to 0.01 m , therefore we now have to multiply the depth of the actual water tower which is in cm by 0.01 to get the actual depth in meters

384 * 0.01 = 3.84m
