Answer:

Estimated probability P=\frac{5}{12}

Step-by-step explanation:

In this question Emil estimates the probability of 2 or more heads coming up in 3 coin flips.

He has a computer which randomly selects 0 or 1 three times, with 0 representing heads and 1 as tails.

From the results shown we will select the preferred events of getting 2 or more heads, means results having 2 zeros or more than 2 zeros.

Number of preferred events are = 5

And total events are = 12

Therefore estimated probability = P=\frac{\text{Preferred events}}{\text{Total events}}

Probability P=\frac{5}{12}

Therefore answer is P=\frac{5}{12}

If the simple interest on ​$3,000 for 8 years is ​$1,680​, then what is the interest​ rate?
madam [21]

We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years

In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.

Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...

Answer:

16.7

Step-by-step explanation:

We can use the Pythagorean theorem, a^2 + b^2 = c^2.

a = 11

c = 20

11^2 + b^2 = 20^2

121 + b^2 = 400

b^2 = 279

b = sqrt(279) = 16.7

Andre notices that he is a little taller than Lin but is shorter than their math teacher, who is 164 centimeters tall. Write two
Ugo [173]

Answer:

Andre's height:  y < x < 164

Step-by-step explanation:

We will first of all convert each of the statements to mathematical inequalities, before we combine them.

Let Andre's height be = x

Lin's height be = y

The maths teacher's height = 164

Andre is a little taller than Lin:

x > y

Andre is shorter than their maths teacher, who is 164 centimetres

x<164

Combining the two inequalities, we have Andre's height as

y < x < 164

This means that Lin is shorter than Andre who is in turn shorter than the Maths Teacher.
