Answer:

a = 127 kg

b = 55 kg

Step-by-step explanation:

a + b = 182

a - 36 = b + 36

   + 36      + 36

a = b + 72

 

(a) + b = 182

(b + 72) + b = 182

2b + 72 = 182

      -72    -72

2b = 110

÷2    ÷2

b = 55

a + (b) = 182

a + (55) = 182

   - 55      - 55

a = 127

{127 - 36 = 91}

{55 + 36 = 91}

{91 + 91 = 182}

4. Use the diagram below to answer the question
ludmilkaskok [199]

Answer:

≈ 397 m

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Let h represent the height of the balloon above ground, then

h² + 50² = 400², that is

h² + 2500 = 160000 ( subtract 2500 from both sides )

h² = 157500 ( take the square root of both sides )

h ≈ 397 m ( to the nearest metre )

A researcher reports a 98% confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be [0.34,
Fantom [35]

Answer:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Step-by-step explanation:

For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Twice the difference of a number + -3 is 4 find the number
NNADVOKAT [17]

Answer:

The number is 5

Step-by-step explanation:

If we need to find the hidden number, Which for simplicity's sake we will denote as "n", lets first write out the equation.

"2 x [n + (-3)] = 4"

We can work through this problem backwards. if we need two times the sum of "n" and (-3) to get to 4, the only number that can be multiplied by 2 to get a product of 4 is 2, so "n" + (-3) must equal 2. so, From here, we can figure out that since 5 + (-3) equals 2, "n" Must equal 5. so, if we plug in 5 for "n" the equation looks like this:

"2 x [5 + (-3)] = 4"

So, since the equation makes sense, the answer is, "n = 5"
