Answer:
A. 3.25x + 13.50 ≤ 40
The number of bracelets is x. It's a variable.
The 13.50 is a constant.
The total needs to be less than or equal to 40 because that's all the money he has.
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
Answer:
a
The percentage is
b
The probability is
Step-by-step explanation:
From the question we are told that
The population mean is
The variance is
The range consider is
The value consider in second question is
Generally the standard deviation is mathematically represented as
substituting value
The percentage of a cucumber give the crop amount between 778 and 834 kg is mathematically represented as
Generally
So
From the z-table the value for
and
So
The percentage is
The probability of cucumber give the crop exceed 900 kg is mathematically represented as
substituting values
From the z-table the value for
Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
step 1
Find the length side c
Applying the Pythagoras Theorem
substitute the given values
step 2
Fin the measure of angle B
we know that
In the right triangle
substitute the given values
step 3
Find the measure of angle A
we know that
The measure of interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
Remember that in a right triangle the measure of angle C is 90 degrees
we have
substitute
