2) A fair coin was tossed 75 times. The coin landed on Heads 42 times and Tails 33 times. What is the experimental probability of the coin landing tails side up? Your answer needs to be a fraction in simplest form. Grid in boxes below. One digit/symbol per box, 7. SP.6 5) Tanya set a goal to swim 30
Answers
Answer:
[tex]\frac{11}{25}[/tex]
Step-by-step explanation:
In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...
[tex]\frac{33}{75}[/tex] or 0.44
This fraction can also be simplified to its simplest form of [tex]\frac{11}{25}[/tex] which is obtained by dividing both the numerator and denominator by 3

Answers
Answer:
$26.80
Step-by-step explanation:
(I don't know exactly how other people were taught to do percentages, but this is how I was taught and I find it the easiest for me.)
You are going to subtract your percentage number by 100.
100 - 33 = 67
This will give you your multiplier so you can then get your answer but you have to turn it into a decimal.
0.67 x 40 = 26.80

A train leaves at 14.54 and arrives at its destination at 15.47.
If the train travelled 66 km, what was it's average speed in km/h?
Give your answer rounded to 1 dp.
km/h
Answers
Answer:
74.7 km/h
Step-by-step explanation:
The computation of the average speed is shown below:
As we know that
Speed = Distance ÷ Time
where
Distance = 66 km
And, the time is from 14.54 to 15.47 is 53 minutes
So, the speed is
= 66 km ÷ 53 minutes
= 74.71698 kilometers per hour
= 74.7 km/h

Answers
Answer:
Step-by-step explanation:
1). x² - 8x
To convert this expression into a perfect square trinomial,
x² - 2(4x) + 4² = (x - 2)²
Therefore , 4² = 16 should be added.
Option (4) is the answer.
2). x² + 2x = 3
x² + 2(1)(x) = 3
x² + 2(1)(x) + 1 = 3 + 1 [By adding 1 on both the sides]
(x + 1)² = 4
x + 1 = ±2
x = -3, -1
Option (1) is the answer.
3). 3x²- 18x = 21
x² - 6x = 7
x² - 2(3x) = 7
x² - 2(3x) + 3² = 7 + 3²
(x - 3)² = 7 + 9
(x - 3)² = 16
x - 3 = ±4
x = -1, 7

Lori bought some cookies for $2 each and muffins for $3 each. She bought twice as
many muffins as cookies and spent $16. How many cookies did Lori buy?
Answers
Answer:
2 cookies
Step-by-step explanation:
let c represent cookies, m represent muffins. set up a system of equations:
2c+3m=16
m=2c
(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).
then solve the system of equations by substitution, substituting 2c for m in the top equation:
2c+3(2c)=16
2c+6c=16
8c=16
c=2
this means that lori bought 2 cookies.
Answer:
2 cookies
Step-by-step explanation:
let c = no. of cookies
2c = no. of muffins
The cost for c cookies is 2c since each cookie was $2
and the cost of 2c muffins is 3(2c) = 6c since each muffing was $3
The total cost = 2c + 6c = 16
8c = 16
c = 2
So, she bought 2 cookies and 4 muffins
A grocery store sells 3 pounds of Granny Smith apples for $6.27. It sells 5 pounds of Red Delicious apples for $9.95. Which costs more per pound?
Answers
The Granny Smiths apples sells it for 2.09 per pound. Red delicious sells it for 1.99 per pound.
Step by step
Divide 6.27 by 3 you’ll get 2.09
Divide 9.95 by 5 you’ll get 1.99
And 2.09 is greater then 1.99 so Granny Smith sells it for more
