Answer:
5% of 30 is 1.5
25% of 30 is 7.5
25% is one quarter. 5% is a fifth of a quarter.
Answer:
5% of 30 is = 30 x 0.05 = 1.5
25% of 30 is 30 x 0.25 = 7.5
The difference is 6

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
Answer:
1.53 times
Step-by-step explanation:
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
We would have:
First strain : Second strain
0.000000143 mm : 0.0000000937 mm
How much larger is the first strain than the second?
We divide both by the length of the second strain
0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937

Janie has 2 3/4 yards or yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
Answer:
1 3/8 yards
Step-by-step explanation:
Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
The above question is calculated as:
2 3/4 yards × 1/2 of ribbon
= 2 3/4 × 1/2
= 11/4 × 1/2
= 11/8
= 1 3/8 yards
Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks

Answer:
[tex]a_{15} = 2147483648[/tex]
Step-by-step explanation:
first, find the common ratio (r) by dividing the second term by the first term:
r = 32 / 8 = 4
next, write a formula for the geometric sequence:
[tex]a_{n} = a_{1} * (r)^{n-1} \\a_{15} = 8 * (4)^{14} \\a_{15} = 2147483648[/tex]
A survey of 50 randomly selected students showed that 38 students buy lunch at school and 12 students bring lunch from home each day. Name the sampling Technique AND if that method is biased or unbiased.
Answer:
We know that our sample is a group of 50 randomly selected students.
First, we want to know the name of the sampling technique.
There are a lot of sampling techniques, but knowing that the students are selected randomly, we can conclude that this is the simple random sampling technique, where each individual is chosen entirely by chance (so all the students have the same probability of being chosen)
Now we want to know if the method is biased or not,
Always that we use the simple random sampling technique, we will have an unbiased sample.

The equation of the line is of the form y = mx, What is the value of m?
Answer:
-4
Step-by-step explanation:
m is the slope
Answer:
m=-4
Step-by-step explanation:
in the formula y=mx, m is the slope. You can find it by looking at the graph, and finding two points that are defined on the grid. In this case, we can use (0,0) and (-1,4). Put it into the slope formula, (y2-y1)/(x2-x1). In this case, it would be (4-0)/(-1-0), which simplifies to 4/-1=-4. Therefore, m= -4

The flight path of a plane is a straight line from city J J to city K K. The roads from city J J to city K K take the long way around, traveling 9.4 9.4 miles south and then 15.1 15.1 miles east. How many degrees east of south is the plane's flight path, to the nearest tenth? M ∠ J ≈ ? M∠J≈
Answer:
58.1 degrees
Step-by-step explanation:
Given the following
JK = 9.4miles (towards south) negative y axis
If the move 15.1 miles towards east (that will be towards the positive x axis)
Using the SOH CAH TOA identity
opposite= 15.1 miles(side facing m<J)
adjacent= JK = 9.4miles
tan theta = opposite/adjacent
tan m<J = 15.1/9.4
tan m<J = 1.6063
m<J = arctan (1.6063)
m<J = 58.09 degrees
Hence the measure of m<J to the nearest tenth is 58.1 degrees

O g(x) = -4(2)
O g(x) = 4(2)**
O g() = -43)
O g(x) = 4(1)
000
Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x
Step-by-step explanation:
What is the solution for the graph to the right?
Answer:
If you're looking for the equation that represents this graph, it would be y=2x+1. Hope this helps :)
