What is the value of s in the equation below? S + 1 1/2 = 10 1/2
Answer:
S=9
Step-by-step explanation:
10[tex]\frac{1}{2}[/tex] - 1[tex]\frac{1}{2}[/tex] = 9
Answer:
s=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
s+3/2=21/2
Step 2: Subtract 3/2 from both sides.
s+3/2−3/2=21/2−3/2
s=9

Suppose that the effects of copper on a second species (say, species B) of fish show the variance of ln(LC50) measurements to be .8. If the population means of ln(LC50) for the two species are equal, find the probability that, with random samples of ten measurements from each species, the sample mean for species A exceeds the sample mean for species B by at least 1 unit.
Answer:
Hello the reference related to your question is missing attached below is the reference
answer : p ( x - y ≥ 1 ) = 0.0019
Step-by-step explanation:
Assuming 'X' and 'Y' are independent random samples
X : mean value = [tex]U_{1}[/tex] , variance = 0.4 /10 = 0.04
Y : mean value = [tex]U_{2}[/tex] , variance = 0.8/10 = 0.08
since the values are independent
V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12
Determine the probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit
P ( x - y ≥ 1 ) = 0.0019
attached below is the detailed solution

Select all equations that represent this question: "Priya is stacking building blocks to make a tower. She takes a break when the tower is 2/2 feet tall, which is a of the height of the tower she wants to build. How tall is the tower when finished
5/8 * ? = 2 1/2
5/8 ÷ 2 1/2 = ?
2 1/2 * ? = 5/8
2 1/2 * 5/8 = ?
2 1/2 * 8/5 =?
2 1/2 ÷ 5/8 = ?
Answer:
c
Step-by-step explanation:
The answer is c
Answer:
5/8 * ? = 2 1/2
Step-by-step explanation:
x is the height of tower when finished.
We know that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 off the height of the tower she wants to build.
This means that 5/8 of x equals 2 and 1/2 Let us represent this information in an equation.
5/8 × x = 2 and 1/2
Convert our given mixed fraction into improper fraction.
5/8 × x = 5/2
Multiply both sides of our equation by 8/5.
(8/5 × 5/8) × x = (5/2 × 8/5)
x = 8/2
x = 4

What is the measure of angle x?
Answer:
47+47+90+90= 274, 360-274= 86, 86÷2=43=x
Answer:
x = 43°Step-by-step explanation:
So here angle x is equal to the angle between 90° and 47° ( Vertically Opposite Angles are Equal.
So, if we use algebra
[tex]90 + x + 47 = 180 \\ 137 + x = 180 \\ x =180 - 137 \\ x = 43[/tex]
So the the missing angle is equal to 43

Which of the following rational functions is graphed below?
O A. F(X) =
2x
x(x - 2)
B. F(x) =
1
x(x - 2)
C. Fix) =
1
x(x - 2)
D. F(x) =
x + 1
(x + 2)(x +0)
Answer:
Huh? I'm not sure what you're asking try C
Answer:
B. f(x) = 1/x(x - 2)Step-by-step explanation:
The graphed function has two vertical asymptotes.
The functions A and D have degree 1 on the numerator and degree 2 on the denominator, so finally having degree 1, have one vertical asymptote, therefore discounted.We are left with B and C.
Function B has vertical asymptotes 0 and -2.
This is matching the graph, correctFunction C has vertical asymptotes 0 and 2
This is not matching the graph, incorrectSee the attached to confirm
Use the order of operation to evaluate the expression below
4+[8 ÷(8-7) +6 -12] . 10
First do inside the parentheses:
4 + [8/1 + 6-12] . 10
Now work inside the brackets doing division first
4 + [8 + 6 -12]. 10
Still inside the brackets add an subtract from left to right:
4 + 2 . 10
Multiply:
4 + 20
Add to get final answer of 24
Answer:
4+[8 ÷(8-7) +6 -12] . 10
4+[8÷1+6-12].10
4+[8+6-12].10
4+[14-12].10

cosA-sinA+1/cosA+sinA+1=1-sinA/cosA
Answer:
steps below
Step-by-step explanation:
(cosA-sinA+1) * cosA = cos²A - sinA cosA + cosA
= (1 - sin²A) - sinA cosA + cosA + sinA - sinA
= cosA + sinA + 1 - sinA cosA -sin²A - sinA ..Re-group
= (cosA + sinA + 1) - sinA (cosA + sinA + 1)
= (cosA + sinA + 1) * (1 - sinA)
(cosA-sinA+1) / (cosA + sinA + 1) = (1 - sinA) / cosA
