I need to find x
[calling 10th graders or geometry]
will give brainliest and + points please!
angles sum: 180(6-2) = 720
50 + 37 + 42 = 129
129 + 5x + 7x - 1 + 3x + 40 = 720
15x + 168 = 720
15x = 552
x = 36.8
check:
129 + 5(36.8) + (3(36.8) + 40) + (7(36.8) - 1) = 720
Correct answer??
180-50 = 130
180-37 = 143
180-42 = 138
Known internal angles:
130 + 143 + 138 = 411
15x + 39 + 411 = 720
15x = 270
x = 18

Trevor is interested in purchasing the local hardware/sporting goods store in the small town of Dove Creek, Montana. After examining accounting records for the past several years, he found that the store has been grossing over $850 per day about 65% of the business days it is open. Estimate the probability that the store will gross over $850 for the following. (Round your answers to three decimal places.)
(a) at least 3 out of 5 business days
(b) at least 6 out of 10 business days
(c) fewer than 5 out of 10 business days
(d) fewer than 6 out of the next 20 business days If the outcome described in part (d) actually occurred, might it shake your confidence in the statement p = 0.65? Might it make you suspect that p is less than 0.65? Explain. Yes. This is unlikely to happen if the true value of p is 0.65. Yes. This is likely to happen if the true value of p is 0.65. No. This is unlikely to happen if the true value of p is 0.65. No. This is likely to happen if the true value of p is 0.65.
(e) more than 17 out of the next 20 business days If the outcome described in part (e) actually occurred, might you suspect that p is greater than 0.65? Explain. Yes. This is unlikely to happen if the true value of p is 0.65. Yes. This is likely to happen if the true value of p is 0.65. No. This is unlikely to happen if the true value of p is 0.65. No. This is likely to happen if the true value of p is 0.65.
Answer:
A) P(X ≥ 3 ) = 0.7648
B) P(X ≥ 6) = 0.7515
C) P(X < 5) = 0.0949
D) P(X < 6) = 0.00031113
Yes. This is likely to happen if the true value of p is 0.65
E) P(X ≥ 17) = 0.012118
No. This is unlikely to happen if the true value of p is 0.65
Step-by-step explanation:
Solving this question means we have to deal with binomial probability distribution which follows a formula;
P(X = x) = C(n, x) * p^(x) * (1 - p)^(n - x)
We are given p = 65% = 0.65
A) probability of getting At least 3 out of the 5 business days, we have;
P(X ≥ 3 ) = P(X = 3) + P(X = 4) + P(X = 5)
And n = 5
Thus;
P(X = 3) = C(5, 3) × 0.65³ × (1 - 0.65)^(5 - 3)
P(X = 3) = 0.3364
P(X = 4) = C(5, 4) × 0.65⁴ × (1 - 0.65)^(5 - 4)
P(X = 4) = 0.3124
P(X = 5) = C(5, 5) × 0.65^(5) × (1 - 0.65)^(5 - 5)
P(X = 5) = 0.116
Thus;
P(X ≥ 3 ) = 0.3364 + 0.3124 + 0.116
P(X ≥ 3 ) = 0.7648
B) Probability of getting at least 6 out of the 10 business days.
P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)
From online binomial calculator, we have;
P(X = 6) = 0.2377
P(X = 7) = 0.2522
P(X = 8) = 0.1757
P(X = 9) = 0.0725
P(X = 10) = 0.0134
P(X ≥ 6) = 0.2377 + 0.2522 + 0.1757 + 0.0725 + 0.0134
P(X ≥ 6) = 0.7515
C) probability of getting fewer than 5 out of the 10 business days.
P(X < 5) = P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1)
From online binomial calculator, we have;
P(X = 4) = 0.0689
P(X = 3) = 0.0212
P(X = 2) = 0.0043
P(X = 1) = 0.0005
P(X < 5) = 0.0689 + 0.0212 + 0.0043 + 0.0005
P(X < 5) = 0.0949
D)probability of getting fewer than 6 out of the next 20 business days;
P(X < 6) = P(X = 5) + P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1)
From online binomial calculator, we have;
P(X = 5) = 0.000261
P(X = 4) = 0.000044
P(X = 3) = 0.0000056
P(X = 2) = 0.0000005
P(X = 1) = 0.00000003
P(X < 6) = 0.000261 + 0.000044 + 0.0000056 + 0.0000005 + 0.00000003
P(X < 6) = 0.00031113
Yes, in this scenario, It is likely to happen and I would think p is less than 0.65 because probability is less than 1 out of 1000.
E) probability of getting more than 17 out of the next 20 business days.
P(X ≥ 17) = P(X = 18) + P(X = 19) + P(X = 20)
From online binomial calculator, we have;
P(X = 18) = 0.0099846
P(X = 19) = 0.00195187
P(X = 20) = 0.00018125
P(X ≥ 17) = 0.0099846 + 0.00195187 + 0.00018125
P(X ≥ 17) = 0.012118
Probability is around 12 in 100 and not up to 50%. Thus, This is unlikely to happen if the true value of p is 0.65

Find tan 30°
Answer:
[tex]tan(30) = \frac{A}{B}[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find tan(30)
Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B
So [using tangent identity]:
[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
This gives:
[tex]tan(30) = \frac{A}{B}[/tex]

30 okay P O I N T S
Please anyone help me on this
Answer:
Standard line equation:
y=ax+b
The point (5,1) is on the line. so :
1=a(5)+b → 1=5a+b
The point (1,-5) is also on the line. Then :
-5=a(1)+b → -5=a+b
Subtract the two equations in terms of a and b. we have:
6=4a → a=3/2 , b=-6.5
y=1.5x-6.5

Find the value of the variable
Answer:
x=6
Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6
