If a couple were planning to have three children, the sample space summarizing the gender outcomes would be: bbb, bbg, bgb,

harkovskaia [24]

Answer:

a.S={hh,sh,hs,ss}

b.tex]\frac{1}{4}[/tex]

c. $\frac{1}{2}$

Step-by-step explanation:

We are given that a sample space of three children

S={bbb,bbg,bgb,bgg,gbb,gbg,ggb,ggg}

a.We have to construct similar space for two children where h for healthy and s for sick.

Then the sample space of two children

S={hh,sh,hs,ss}

b.Number of cases favorable to two healthy children=1

Total number of cases=4

Number of cases for two healthy children=1

Probability =Number of favorable cases divided by total number of cases

Probability= $\frac{1}{4}$

Hence, the probability of getting two healthy children= $\frac{1}{4}$

c.We have to find the probability of getting exactly one healthy child and one sick child

Number of cases of one healthy child and one sick child={hs,sh}=2

Probability= $\frac{2}{4}=\frac{1}{2}$

Hence, the probability of getting exactly one healthy child and one sick child= $\frac{1}{2}$

Jalen bought 4 bottles of water, 2 bags of cashews, and a fruit salad. The cost of the fruit salad was $5. This expression was

grigory [225]

Answer:

water bottles = 3

Step-by-step explanation:

4x + 2x + 5 = 25

1. you need to get rid of the five, so subtract it from both sides

4x + 2x = 20 2. based on the amount you paid you need to find two multiplication problems that will amount to $20 (4x3= 12 <- - water 2x4=8 <-- cashews)

underlined = cost per item

B. 8/27 D. 1/3 10. Three spheres of radii , 2r, and 3r, respectively, are melted and formed into a new sphere. Find the surface

Dahasolnce [82]

Answer:

$A_{f}=4\pi (\sqrt[3]{36} r)^{2}\\\\V_{f}=\frac{4}{3} \pi (36r^{3})$

Step-by-step explanation:

In order to find the final radii of the sphere, we need to calculate the volume, knowing that volumes are additive:

$V_{1}=\frac{4}{3} \pi (r^{3})\\\\V_{2}=\frac{4}{3} \pi (2r)^{3}\\\\V_{3}=\frac{4}{3} \pi (3r)^{3}\\\\V_{f}=\frac{4}{3} \pi (r^{3}+(2r)^{3}+(3r)^{3})\\\\V_{f}=\frac{4}{3} \pi (r^{3}+8r^{3}+27r^{3})\\\\V_{f}=\frac{4}{3} \pi (36r^{3})\\\\V_{f}=\frac{4}{3} \pi R^{3}\\\\R=\sqrt[3]{36} r$

Now that we know the radii of the new sphere, we can calculate the surface area:

$A_{f}=4\pi R^{2}\\\\A_{f}=4\pi (\sqrt[3]{36} r)^{2}$
