Answer:
p = 33/100 = 33%
Step-by-step explanation:
p (probability) = 1.00 - [variables]
p = 1.00 - (0.12 + 0.07 + 0.05 + 0.28 + 0.15)
p = 1.00 - 0.67
p = 33/100

4(6x – 7) = 44
Answer:
x = 3
Step-by-step explanation:
4(6x - 7) = 44
divide both sides by 4
6x - 7 = 11
add 7 to both sides
6x = 18
divide both sides by 6
x = 3
What is d?
-16 (d + 1) = -20
d=?
Answer:
Step-by-step explanation:
Simplify it. -16d-16=-20.
Add 16 to both sides. -16d=-4
Divide 16 by both sides.
d=1/4

if the area of a triangle is 128 sqcm and height is 12cm, find its base?
Area of triangle = 1/2 x base x height
128 = 1/2 x base x 12
Multiply both sides by 2:
256 = base x 12
Divide both sides by 12
Base = 21 1/3 cm

Mellie is conducting a test on mold spores on bread. She uses 6 slices of bread to compare two strains of mold. She applies one strain to the left side of the bread and one strain to the right side. She flips a coin to decide which strain goes on the right side of the bread. The mold spores that appear on each side are counted and she records them in a table.

Considering the t-test applied, the number of degrees of freedom is given by:
d. 10.
What is the number of degrees of freedom of a t-test?For a sample of size n, the number of degrees of freedom is given by:
df = n - 1
When there are m samples, the amount of degrees of freedom is m multiplied by the sum of degrees of freedom of each sample.
In this problem, there are 2 samples with 6 - 1 = 5 df, hence:
2 x 5 = 10.
Option d is correct.

The number of absences for one week for all students at a high school were compiled, and the probability distribution below was created. What is the probability in any given week that a randomly selected student will be absent no more than one day? Probability Distribution Days Absent: X Probability: P(X) 0 0. 78 1 0. 14 2 0. 03 03 2000. 01 4 0 5 0. 04 0. 08 0. 14 0. 78 0. 92.
The probability of randomly selected students who will be absent no more than one day is 0.92. Option D is correct.
What is the probability?
The probability is defined as the number of favorable occurrences of an event.
Given the probability distribution of the number of absence for one week,
x: 0 1 2 3 4 5
P(X): 0.78 0.14 0.03 0.01 0 0.04
We know that the probability of any event is always less than equal to 1. We can write that, [tex]P(x\leq 1)[/tex].
So the probability of randomly selected students who will be absent no more than one day is calculated as given below.
[tex]P = P (x=0) + P(x=1)\\P = 0.78 + 0.14[/tex]
[tex]P = 0.92[/tex]
Hence we can conclude that the probability of randomly selected students who will be absent no more than one day is 0.92. Option D is correct.

Four friends buy cinema tickets using this offer.
Cinema tickets
Buy 3 tickets and get a ticket free
They each pay £7.05
How much does a ticket cost?
t
+
Answer:
7.04*4=x
x/3=how much the tickets cost
Step-by-step explanation:
If each of the four friends pays $7.04, the equation would be set up like this: 7.04*4=28.16. This means the total cost for tickets is 28.16. If the total cost for three tickets is 28.16, just divide the total cost by how many tickets were purchased. 28.16/3=9.39. This means one ticket cost 9.39.
[tex]\longrightarrow \sf £ \:9.4 [/tex]
Solution:-[tex]\leadsto[/tex]Money paid by 1 friend = £ 7.05
[tex]\leadsto[/tex]Money paid by 4 friend = £ 7.05 × 4
[tex] \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad[/tex]= £ 28.2
This is equal to cost of 3 tickets
[tex]\leadsto[/tex] Cost of 3 tickets = £ 28.2
[tex]\leadsto[/tex] Cost of 1 ticket = £ 28.2 ÷ 3
[tex]\quad\quad\quad\quad\quad\quad\quad\quad\quad[/tex]=£ 9.4
Thus , each ticket cost £ 9.4 .

on Saturday five girls held a car wash to earn money for each car they charged $6 the girls washed a total of 22 cars and collected an extra $10 in tips if they divide the money equally how much will each girl receive
This is due at 4:20 Can you please help
Answer:
$28.40
Step-by-step explanation:
First let's find how much they earned from washing the cars. They charged $6 for each car and washed 22 so 6x22=$132 from washing cars. After that they earned 10 more dollars so we have to add that. 132+10=$142 earned in total. Then we have to divide this total income between all of the girls. 142/5=$28.40 for each girl.
Sean works at a book shop. He finds that when a book is chosen from the shop at random, the following probabilities are correct: P(non-fiction) = 0.37 P(paperback) = 0.23 P(both non-fiction and paperback) = 0.18 - Work out P(neither non-fiction nor paperback) as a decimal.

Answer:
220°
Step-by-step explanation:
[tex]\angle PQM [/tex] is inscribed in the [tex]\widehat{PQM}[/tex] and [tex]\widehat{PNM}[/tex] is intercepted by it.
Therefore, by inscribed angle theorem:
[tex]m\angle PQM =\frac{1}{2}\times m\widehat{(PNM)}[/tex]
[tex]\implies 110\degree =\frac{1}{2}\times m\widehat{(PNM)}[/tex]
[tex]\implies 110\degree \times 2= m\widehat{(PNM)}[/tex]
[tex]\implies m\widehat{(PNM)}= 220\degree [/tex]
