Answer:
Since 342 hundredths is 342 over one hundred, 342 hundredths as a Fraction is 342/100. If you divide 342 by one hundred you get 342 hundredths as a decimal which is 3.42. To get 342 hundredths as a Percent, you multiply the decimal with 100 to get the answer of 342 percent.
Answer:3.42
Step-by-step explanation:
A thumbtack that is tossed can land point up or point down. The probability of a tack landing point up is 0.2. A simulation was conducted in which a trial consisted of tossing 5 thumbtacks and recording the number of thumbtacks that land point up. Many trials of the simulation were conducted and the results are shown in the histogram.
Based on the results of the simulation, which of the following is closest to the probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed?
A 0.09
B 0.19
C 0.28
D 0.72
E 0.91
Answer:
Option C: 0.28
Step-by-step explanation:
This is a binomial probability distribution problem.
Now, we want to find the probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed. This is written as;
P(X ≥ 2) = P(2) + P(3) + P(4) + P(5)
From the histogram;
P(5) = 0.02
P(4) = 0.02
P(3) = 0.05
P(2) = 0.19
Thus;
P(X ≥ 2) = 0.19 + 0.05 + 0.02 + 0.02
P(X ≥ 2) = 0.28
From the histogram, it is found that there is a 0.28 = 28% probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed, option C.
------------------
The probabilities given by the histogram are:
[tex]P(X = 0) = 0.33[/tex]
[tex]P(X = 1) = 0.39[/tex]
[tex]P(X = 2) = 0.19[/tex]
[tex]P(X = 3) = 0.05[/tex]
[tex]P(X = 4) = 0.02[/tex]
[tex]P(X = 5) = 0.02[/tex]
The probability of at least 2 up is:
[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.019 + 0.05 + 0.02 + 0.02 = 0.28[/tex]
0.28 = 28% probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed, option C.

twice the square of a number
Answer:
2 * x^2
Step-by-step explanation:
in word form: two times the square of x
"a number" can be any variable; i used x
Answer:
x² × 2
Step-by-step explanation:
Notice vocabulary:
twice → multiplication by a factor of two → ×2a number → unknown number; variable → xthe square → raised to the power of two → x²Put this information together.
"Twice the square of a number"
Since it says of a number, this number comes first → [tex]x[/tex]
"Twice the square of a number"
The square of a number means that the variable will be squared → [tex]x^2[/tex]
"Twice the square of a number"

What rule can you write about where the numbers in an inequality with a greater than symbol lie in relation to each other on the horizontal number line?
Answer:
For inequalities with a less than sign (<), the first number is always to the left of the second number on the horizontal number line.
Step-by-step explanation: I had it as a question.
The first number is always to the left of the second number in inequalities with a less-than sign ().
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let's assume an inequality,
y < x
Which represents that x has a greater value than y, and also on the horizontal number line, the first number is always to the left of the second number in inequalities with a less-than sign ().
Thus, The first number is always to the left of the second number in inequalities with a less-than sign ().

Answer:

Solution:
First, you need to add all sides which will give you 147. Then, to find the length of GA, you need to subtract the perimeter which is 167, by 147 which will give you 20. GA = 20
Thus to find G'A', you need to cross multiply 14/35 = G'A'/20
You should end up with 280 = 35. Divide 35 by 280 and you get 8.

(Round your answers to two decimal places.)
(a) 95% confidence, n = 17
We find our degrees of freedom first
= n - 1
= 17 - 1
= 16
The t critical value using the t table =
2.120
(b) 90% confidence, n = 12
We find our degrees of freedom first
= n - 1
= 12 - 1
= 11
The t critical value using the t table =
1.796
(c) 99% confidence, n = 24
We find our degrees of freedom first
= n - 1
= 24 - 1
= 23
The t critical value using the t table = 2.807
(d) 90% confidence, n = 24
We find our degrees of freedom first
= n - 1
= 24 - 1
= 23

Step-by-step explanation:
please tell me what you got when you receive an answer
Answer:
30 degrees
Step-by-step explanation:
we need to compute angle A and angle B (see figure below)
hence,
[tex]cosA=\frac{20}{40}\\ cosA=\frac{1}{2}[/tex]
this implies that A=60 degrees.
Since interior angles of a triangle add up 180 then,
A+B+90=180
60+B+90=180
B+150=180
B=180-150
B=30 degrees
which is the smallest angle

How do you do this question?
Answer:
y = Ce⁻ᵗ − 7
Step-by-step explanation:
dy/dt = -y − 7
dy/dt = -1 (y + 7)
Separate the variables.
dy / (y + 7) = -1 dt
Integrate both sides.
ln│y + 7│= -t + C
Solve for y.
y + 7 = e⁻ᵗ⁺ᶜ
y + 7 = eᶜ e⁻ᵗ
eᶜ is another arbitrary constant, so:
y + 7 = Ce⁻ᵗ
y = Ce⁻ᵗ − 7

Answer:
185
Step-by-step explanation:
firstly you calculate all in brackets
(280+20)÷3
300÷3
100-15
85
now you calculate 10×5=50
2×50=100
85+100=185
so firstly deal with problem inside the brackets, then you got multiplication and division outside their brackets and finally get 85 +100 =185
