Answer:
22°
Step-by-step explanation:
Triangle KJL ≅ Triangle MJL (RHS)
[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]
we come up to the conclusion that 4x + 6 = 3x + 10
x = 4
∴angle KJL = 4(4) + 6 = 22°

Answer:
[tex]\frac{9}{14} \ chance[/tex]
Step-by-step explanation:
1. Approach
Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, [tex]\frac{desired\ outcomes}{total\ outcomes}[/tex].
It is given that
- (63) paid with cash
- (22) paid with a debit card
- (13) paid with a credit card
First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.
2. Find the total number of customers
Add up all of the given customers, regardless of their payment type.;
[tex](cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98[/tex]
(98) total customers.
3. Find the probability
Now set up the probability, remember, the formula for finding the probability is,
[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]
The desired outcome is the number of customers who pay with cash = (63)
The total outcome is the number of customers who when to the business; (98)
Substitute in the numbers and simplify,
[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]
[tex]\frac{63}{98}[/tex]
Both of these numbers are divisible by (7), hence divide the fraction by (7)

The age of trees in a forest is known to be approximately normal with an average age of 40 years and a standard deviation of 10 years. About ____ of the trees have ages between 10 years and 70 years.
Answers
Answer:
Not 95%
Step-by-step explanation:
The normal distribution is also known as the Gaussian distribution. About 99.7% of the trees have ages between 10 years and 70 years.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the age of the tree is normally distributed. Also, the following details are known,
Standard Deviation, σ = 10 years
Mean, μ = 40
Now, the z-score and the p-values for the value of 70 and 10 can be written as,
Z = (X-μ)/σ
Z = (70 - 40)/10
Z = 3
The p-value for z-score of 3 is 0.9987.
Z = (X-μ)/σ
Z = (10 - 40)/10
Z = -3
The p-value for z-score of -3 is 0.0013.
Further, the percentage of the trees have ages between 10 years and 70 years is,
Percentage = 0.9987 - 0.0013
= 0.9974
= 99.7%
Hence, About 99.7% of the trees have ages between 10 years and 70 years.

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will it takes the plant to reach one foot.
Answers
Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks
