Trygg has 3/4 package of marigold seeds. He plants 1/6 of those seeds in his garden, then he plants exactly

\dfrac{3}{4}\cdot \dfrac{1}{6} =\dfrac{3\cdot 1}{4\cdot 6}= \dfrac{3}{24} =\dfrac{1}{8}

of seeds.

Now count how much of package left:

\dfrac{3}{4}-\dfrac{1}{8} =\dfrac{6}{8}-\dfrac{1}{8} =\dfrac{6-1}{8}=\dfrac{5}{8}.

He divides the rest \left(\dfrac{5}{8}\right) equally into 10 flowerpots, then in each flowerpot is planted

\dfrac{\dfrac{5}{8}}{10}=\dfrac{5}{8} \cdot \dfrac{1}{10}=\dfrac{5\cdot 1}{8\cdot 10}=\dfrac{1}{16}.

Answer: in each flowerpot is planted \dfrac{1}{16} package of marigold seeds.

A map has a scale of 3 cm: 18 km. If Riverside and Smithville are 54 km apart then how many cm is that on a map?
Sladkaya [172]

Answer:

9 cm

Step-by-step explanation:

If the scale is 3cm:18 km, then x cm : 54km will be the distance between Riverside and Smithville. Since 18 *3 = 54 then 3cm * 3 = 9cm. On the map they are 9 cm apart.

SVETLANKA909090 [29]

Complete question:

Consider a class of 20 students consisting of 5 sophomores, 8 juniors, and 7 seniors. A math instructor assigns a group project in each of the scenarios below, the instructor selects 5 consecutive students from this class, keeping track (in order) of the level of the student that he gets.

1a. How many possible outcomes are in the sample space S? (An outcome is a 5- tuple of students.)

Let A2 denote the event that exactly 2 of the selected students are sophomore, A5 denote the event that exactly 5 of the selected students are the juniors, and A4 denote the event that exactly 4 of the selected students are seniors.

1b. Find the probabilities of each of these three events. A2, A5, A4

1c. Do the events A2, A5, A4 constitute a partition of the sample space?

Answer:

Given:

n = 20

a) The possible outcome in the sample space,S, =

ⁿCₓ = ²⁰C₅

= \frac{20!}{(20-5)! 5!)}

= \frac{20*19*18*17*16}{5*4*3*2*1}

= 15504

b) probabilities of A2, A5, A4

P(A2) = ⁵C₂ / ²⁰C₂

= \frac{20}{320} = \frac{1}{19}

P(A5) = ⁸C₅ / ²⁰C₅

= \frac{56}{15540} = \frac{7}{1938}

P(A4) = ⁷C₄ / ²⁰C₄

= \frac{35}{4845} = \frac{7}{969}

c) No,the events A2, A5, A4, do not comstitute a partition of the sample space. i.e P(A2)+P(A5)+P(A4) ≠ 1

Select the statement in if-then form.
SashulF [63]
The correct statement is C. <span>If an angle is an acute angle, then the angle measures less than 90 degrees. 
A and B are obviously incorrect, and D is incorrect because it can be other angle as well, not just acute. </span>
