Solution :

P(A) = 0.2

[tex]$P(B)=0.3$[/tex]

[tex]$P(C)=0.5$[/tex]

Each portfolio has both the stocks and the bonds, and the investors are equally likely to choose either of them.

Let Stock = S

      Bond  = b

Therefore, we have:

[tex]$P(S|A) = 0.5$[/tex]

[tex]$P(b|A) = 0.5$[/tex]

[tex]$P(S|B) = 0.5$[/tex]

[tex]$P(b|B) = 0.5$[/tex]

[tex]$P(S|C) = 0.5$[/tex]

[tex]$P(b|C) = 0.5$[/tex]

Therefore,

[tex]$P(b \text{ and } B)= P(b|B) \times P(B)$[/tex]

                    = 0.5 x 0.3

                    = 0.15

Based on the tree diagram, probability of an investor choosing only bonds from portfolio B is 0.15.

Probability is the chance or likelihood of an event occurring.

Mathematically, probability is given as;

From the tree diagram:

P(A) = 0.2

P(B) = 0.3

P(C) = 0.5

The investors are equally likely to choose from each portfolio.

Each portfolio has both the stocks and the bonds.

Assuming stock = S and Bond = B.

Then;

P(S|A) = 0.5

P(b|A) = 0.5

P(S|B) = 0.5

P(b|B) = 0.5

P(S|C) = 0.5

P(b|C) = 0.5

[tex]P(b \text{ and } B)= P(b|B) \times P(B)[/tex]

[tex]P(b \text{ and } B)= 0.5 \times 0.3 = 0.15[/tex]

Therefore, the probability of an investor choosing only bonds from portfolio B is 0.15.

Answer:

The fraction of the drink that is juice is [tex]\frac{2}{13}[/tex]

Step-by-step explanation:

Since the ratio of the water to juice is 11:2, that means the ratio of juice to the total amount of liquid in the glass would be [tex]\frac{2}{11+2}[/tex] or [tex]\frac{2}{13}[/tex].

The fraction of the drink that is juice is [tex]\( \frac{2}{13} \)[/tex].

The ratio of water to juice in the glass is 11:2. This means that for every 11 parts of water, there are 2 parts of juice in the drink.

To find the fraction of the drink that is juice, we need to add the number of parts of juice and water together. In this case, we have 11 parts of water and 2 parts of juice, making a total of [tex]\(11 + 2 = 13\)[/tex] parts.

Now, to find the fraction of juice in the drink, we divide the number of parts of juice by the total number of parts in the drink. So, we have:

[tex]\( \text{Fraction of juice} = \frac{\text{Number of parts of juice}}{\text{Total number of parts}} = \frac{2}{13} \).[/tex]

Thus, [tex]\( \frac{2}{13} \)[/tex] of the drink is juice.

In summary, to find the fraction of juice in the drink, we first add the number of parts of juice and water together to get the total parts in the drink.

Then, we divide the number of parts of juice by the total parts to find the fraction of juice. In this case, the fraction of juice in the drink is [tex]\( \frac{2}{13} \).[/tex]

Answer:

$255

Step-by-step explanation:

First, we need to generate an equation in slope-intercept form, y = mx + b, that represents the graph. To do this, we need to find b = initial value (y-intercept) and m = slope (money she puts in her account each week).

x = number of weeks

y = balance ($)

✔️Slope (m) = change in y/change in x

Using two points on the line, (1, 45) and (2, 60),

Slope (m) = (60 - 45)/(2 - 1) = 15/1

m = 15

✔️To find b, substitute (x, y) = (1, 45) and m = 15 into y = mx + b.

45 = 15(1) + b

45 = 15 + b

45 - 15 = b

30 = b

b = 30.

✔️To write the equation, substitute m = 15 and b = 30 into y = mx + b

y = 15x + 30

✔️To determine how much Tina will have in her account (y) after 15 weeks (x) of mowing, substitute x = 15 into y = 15x + 30:

y = 15(15) + 30

y = 225 + 30

y = 2

Therefore, Tina will have $255 in her accounts after 15 weeks of mowing lawns.

Answer:

The area is: [tex]69m^2[/tex]

Step-by-step explanation:

Given

[tex]A= \frac{1}{2}(b_1 + b_2) * h[/tex]

[tex]b_1 = 9m[/tex]

[tex]b_2 = 14m[/tex]

[tex]h =6m[/tex]

Required

The area

We have:

[tex]A= \frac{1}{2}(b_1 + b_2) * h[/tex]

This gives:

[tex]A = \frac{1}{2}* (9m + 14m) * 6m[/tex]

[tex]A = \frac{1}{2}* 23m * 6m[/tex]

[tex]A = 69m^2[/tex]

Answer:

B. 90 inches

Step-by-step explanation:

Given that

The length is 50 m

And, the width is 25 m

Scale factor is 3 inches per 5 m

We need to find out the  perimeter of the pool

So,

5 meter = 3 inches

3  ÷ 5 = x ÷ 50

x = 30 inches = length

Now

3  ÷ 5 = x ÷ 50

x = 15 inches = width

Now the perimeter of the pool is

= 2(l + w)

= 2 (30 + 15)

= 90 inches

In this question, we're trying to find how many apples Jenson picked from the basket.

Lets gather information that can help us.

Important information:

• Picked a fruit from a basket 40 times Probability of picking an apple is 0.3

With the information above, we can solve the question.

We know that he picked up a fruit 40 times, but we need to find how many apples he picked up during the 40 times.

The probability of picking an apple is 0.3, which is equivalent to 30%

This means that 30% of the 40 times he picked an apple.

We would multiply 40 by 0.3 to get our answer.

This means that Jenson picked 12 apples.

Answer:

68250

Step-by-step explanation:

Number of ways in which 2 letters can be selected out of 26 letters = 26 c 2 = 26 ! / ( 2! x 24! ) = 325

Number of ways in which 4 digits can be selected out of 10 digits = 10 c 4 = 10 ! / ( 4! x 6! ) = 210

So , total number of ways in which password containing 2 letters & 4 digits can be made = 325 x 210 = 68250

Step-by-step explanation:

Answer: A. 0.01

Step-by-step explanation:

Type I error are refered to as false positives and it means that when a statistically significant difference is validated by the researcher even though the results aren't statistically significant.

Type I error is when one rejects the null hypothesis even though it's actually true. In this case, the inspector rejects the hypothesis which was that the proportion of water that is contained the product is 0.5.

The probability of type 1 error will then be equal to the hypothesis level of significance and this will be 0.01.

Answer:

It is 65 cm

Step-by-step explanation:

Alright, within the image, the triangles ABC and TUV are congruent. With this, the following is true: AB ≅ TU, BC ≅ UV, and CA ≅ VT because the order and their sides between the two triangles is shared.

With this, BC is ≅ to UV. Now, just set the two equations equal to each other:

9x+2=8x+9

9x=8x+7

x=7

Now, we've got x, though it needs to be plugged back into side BC for the final answer

Answer: Option C

l = (P - 2b)/2

Step-by-step explanation:

From P = 2(l + b)

Divide both sides by 2;

P/2 = 2(l + b)/2

P/2 = l + b

l + b = P/2

Make l the subject of formula;

l = (P/2) - b

l = (P - 2b)/2
