Answer:
[tex]P(X \geq 13) = 0.021[/tex]
Step-by-step explanation:
From the question we are told that:
Probability of curing patients P(x)=0.65
Sample size n=14
Generally the Binomial equation is mathematically given by
[tex]P(X) =\frac{(n!)}{X!(n-X)!))} *p^X*(1-p)^(n-X)[/tex]
Generally the equation for Equation for at least 12 cured is mathematically given by
[tex]P(X \geq 13) = P(X = 13)+P(X = 14)[/tex]
For [tex]P(X = 13)[/tex]
[tex]P(X = 13) = (14!/(13!(14-13)!))*0.65^13*(1-0.65)^(14-13) \\\\P(X = 13)= 0.018116[/tex]
For [tex]P(X = 14)[/tex]
[tex]P(X = 14) = (14!/(14!(14-14)!))*0.65^14*(1-0.65)^(14-14) \\\\P(X = 14)= 0.00240318[/tex]
Therefore
[tex]P(X \geq 13) =P(X = 13)+P(X = 14)[/tex]
[tex]P(X \geq 13) = 0.018116+0.00240318[/tex]
[tex]P(X \geq 13) = 0.02051918[/tex]
[tex]P(X \geq 13) = 0.021[/tex]

5m − (m + 4) = 2?
f. -1/2
g. 1/2
h. 1
j. 3/2
k. 3
Answer:
J. 3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
5m−(m+4)=2
Step 1: Simplify both sides of the equation.
5m−(m+4)=2
5m+−1(m+4)=2(Distribute the Negative Sign)
5m+−1m+(−1)(4)=2
5m+−m+−4=2
(5m+−m)+(−4)=2(Combine Like Terms)
4m+−4=2
4m−4=2

Find the domain of the function f left parenthesis x right parenthesis equals cube root of 5 x plus 25 end root
Answer:
Domain is (-∞, ∞)
Step-by-step explanation:
Given function is [tex]\sqrt[3]{5x+25}[/tex]
Please remember, for any cube root function the domain is all real numbers, because the cube root of any real number is a real number.
So, domain is all real numbers.
We can write it in interval notation as (-∞,∞).
Write the equation of the line that is parallel to the line y= -2x+3 and goes through the point (3, -6).
Answer:
y=-2
Step-by-step explanation:
because it's parallel --> a=-2
therefore we have y=-2x+b
the line goes through the point (3,-6) --> (-2).3+b=-6 --> b=0

13. The manager of a landscaping company collected data for an entire summer. Before each job he completely filled the gasoline tank for his mower. After each job, he recorded the square footage of the lawn that was mowed as well as how much gasoline remained in the tank. As expected, larger lawns left him with very little gasoline in the tank. At the end of the season he displayed the data in a scatterplot and saw that the relationship between lawn size and gas remaining was roughly linear. The value of r? was 0.85.Find and interpret the value of the correlation between the lawn size and the amount of gasoline remaining in the tank at the end of the job.

Quadrilateral CDEF is inscribed in circle A. Which statements complete the proof to show that ∠CFE and ∠CDE are supplementary?
Quadrilateral CDEF is inscribed in circle A, so mARC CDE + mARC CFE= 360°. ∠CFE and ∠CDE are inscribed angles, which means that their measures are _________________. So, _________________. Using the substitution property of equality, 2 ⋅ m∠CFE + 2 ⋅ m∠CDE = 360°. Using the division property of equality, divide both sides of the equation by 2, resulting in m∠CFE + m∠CDE = 180°. Therefore, ∠CFE and ∠CDE are supplementary.
Answer:
The statements that complete the proofs are;
First statement
One half the measure of their intercepted arcs
Second statement
mARC CDE = 2·m∠CFE and mARC CFE = 2·m∠CDE
Step-by-step explanation:
The two column proof that ∠CFE and ∠CDE are supplementary is presented as follows;
Statement [tex]{}[/tex] Reason
Quadrilateral CDEF is inscribed is circle A [tex]{}[/tex] Given
[tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex] = 360° [tex]{}[/tex] Measure of angle round a circle
∠CFE and ∠CDE are inscribed angles [tex]{}[/tex] Given
∠CFE + ∠CDE = 1/2 × ([tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex]) [tex]{}[/tex] Inscribed angles are (i) one half the measure of their intercepted arcs
2 × (∠CFE + ∠CDE) = ([tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex])
So, (ii) [tex]m\widehat{CDE}[/tex] = 2 × m∠CFE and [tex]m\widehat{CFE}[/tex] = 2 × m∠CDE From the inscribed angle theorem above (See attached drawing)
2·m∠CFE + 2·m∠CDE = 360° [tex]{}[/tex] Using substitution property of equality
(2·m∠CFE + 2·m∠CDE)/2 = 360°/2 → m∠CFE + m∠CDE) = 180° [tex]{}[/tex] Dividing both sides by 2
m∠CFE and m∠CDE) are supplementary [tex]{}[/tex] Angles that sum up to 180°
The statements that complete the proofs are;
(i) One half the measure of their intercepted arcs
(ii) mARC CDE = 2·m∠CFE and mARC CFE = 2·m∠CDE
Answer:
1/2 the measure of their intercepted arcs; m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2 ⋅ m∠CDE (or C).

We add up all the numbers:
84 + 72 + 96 + 97 + 75 + 83 + 81 = 588
Since there are 7 numbers we divide by 7
588 divided by 7 = 84 is your mean
Step-by-step explanation:
How to find mean:
Add up the numbers, divide by the many numbers there are and thats how you find your mean.
