1. You mix the letters S, U, M, M, E, and R in a bag. Without looking, you select one letter. Find the probability of each event

Lena [83]

Sample space ={S, U, M, M, E, R} = 6 outcomes. Event selecting S: P(S) =1/6 = 16.67% Event selecting U: P(U) =1/6 = 16.67% Event selecting M: P(M) =2/6 = 1/3 = 33.34% Event selecting E: P(E) =1/6 = 16.67% Event selecting R: P(R) =1/6 = 16.67%

Can someone please help.

zvonat [6]

Answer:

8 jars

Step-by-step explanation:

Let the number of jars is x.

<u>80 liters distributed, each jar has:</u>

80/x

<u>Redistribution with 4 less jars, each jar now has:</u>

80/(x - 4)

<u>Each jar has now twice the amount:</u>

80/x*2 = 80/(x - 4)
2/x = 1/(x - 4)
2(x - 4) = x
2x - 8 = x
x = 8

She prepared 8 jars at the start

The diameter is a circle is 16in. Find it’s circumference in terms of π.<br><br> C= ________in

DIA [1.3K]

<h3><u>S</u><u> </u><u>O</u><u> </u><u>L</u><u> </u><u>U</u><u> </u><u>T</u><u> </u><u>I</u><u> </u><u>O</u><u> </u><u>N</u><u> </u><u>:</u></h3>

According to the question,

Diameter of circle = 16 in

We are asked to calculate it’s circumference in terms of π.

★ Circumference of circle = 2πr

___________________________________

Let us first calculate the radius of the circle.

→ Diameter = 2 × Radius

→ 16 in = 2r

→ r = 16 in ÷ 2

→ r = 8 in

___________________________________

Substituting values in the formula of circumference,

→ C = 2πr

→ C = (2 × π × 8) in

→ C = 16π in

<u>Therefore</u><u>,</u><u> </u><u>1</u><u>6</u><u>π</u><u> </u><u>inches</u><u> </u><u>is</u><u> </u><u>the</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>

A 20 ft. ladder is used against a 15 ft. wall. What is the measure of the angle made by the ladder and the ground (nearest whole

Brrunno [24]

Step-by-step explanation:

Given that,

The length of a ladder, H = 20 feet

The height of the wall, h = 15 ft

We know that,

$\sin\theta=\dfrac{h}{H}$

h is perpendicular and H is hypotenuse

So,

$\sin\theta=\dfrac{15}{20}\\\\\theta=\sin^{-1}(\dfrac{15}{20})\\\\\theta=48.59^{\circ}$

Now using Pythagoras theoerm,

$b=\sqrt{H^2-h^2}\\\\b=\sqrt{20^2-15^2}\\\\b=13.2\ ft$

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
