Answer:
25
Step-by-step explanation:
2 out of 12 means also 1 out of 6.
so, a ratio of 1:6 or a factor of 1/6.
150 × 1/6 = 150 / 6 = 25
so, we expect that out of the 150 sold cars 25 have been red.
Is the relationship linear, exponential, or neither?
Mr.russo exchanged 200 euros for 270 dollars how many dollar he get foe 300 euros
Answer:
$405
Step-by-step explanation:
This is a proportion problem!
Build fractions that have euros on top and dollars on the bottom (or the other way around, you decide, but make it the same in both fractions).
Let's do euros over dollars.
Setup:
[tex]\frac{200}{270}=\frac{300}{d}[/tex]
"Cross multiply."
[tex]200d=300\times 270\\\\200d=81000\\\\d=\frac{81000}{200}=405[/tex]
Calculate the average rate of change for the graphed sequence from n = 2 to n = 4.
(2 points)
Answer:
-3.3125[tex]\frac{-10.125-(-3.5)}{4-2} =\frac{-6.625}{2} = -3.3125[/tex]
Step-by-step explanation:
Average rate of change is the slope between two points.
Slope getween points [tex]\left(x_1,\,y_1\right)[/tex] and [tex]\left(x_2,\,y_2\right)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
Using the points (2, -3.5) and (4, -10.125), the slope is
A jewellery shop sells 240 necklaces in a month 180 of the necklaces were sold via the shop website work out the simplest form
Answer:
3 : 1
Step-by-step explanation:
A jewellery shop sells 240 necklaces in a month 180 of the necklaces were sold via the shop website work out the simplest form. The rest were sold in a High Street shop.
Work out the ratio of online sales to shop sales.
Give your answer in its simplest form.
Necklace sold in the shop = 240 - 180 = 60
180 : 60
to convert to simplest form, divide both numbers by 60
3 : 1
State whether the Standardized test statistic T indicates that you should reject the null hypothesis explain a)t=-2.146 b)t=2.014 c)t=2.128 d)t=-2.146
Answer:
[tex](a)\ t = -2.146[/tex]
The null hypothesis is rejected
[tex](b)\ t = 2.014[/tex]
The null hypothesis is accepted
[tex](c)\ t = 2.128[/tex]
The null hypothesis is accepted
[tex](d)\ t = -2.146[/tex]
The null hypothesis is rejected
Step-by-step explanation:
Given
[Missing from the question]
[tex]\alpha = -1.001[/tex] --- critical value
Left tailed test
Required
State what the standardized test statistics indicates
Since it is a left-tailed test, the null hypothesis will be rejected if the standardized test statistics less than or equal to the critical value
Using the above rule, we have:
[tex](a)\ t = -2.146[/tex]
Compare t and [tex]\alpha[/tex]
[tex]-2.146 < -1.001[/tex]
The null hypothesis is rejected
[tex](b)\ t = 2.014[/tex]
Compare t and [tex]\alpha[/tex]
[tex]2.014> -1.001[/tex]
The null hypothesis is accepted
[tex](c)\ t = 2.128[/tex]
Compare t and [tex]\alpha[/tex]
[tex]2.128> -1.001[/tex]
The null hypothesis is accepted
[tex](d)\ t = -2.146[/tex]
Compare t and [tex]\alpha[/tex]
[tex]-2.146 < -1.001[/tex]
The null hypothesis is rejected

Answer:
$45
y = 45x + 15
Step-by-step explanation:
Given :
Days Total Cost
(d) (C)
2. $105
4 $195
6 $285
10 $465
The daily rate is the slope :
Slope = Rise / Run
Slope = (y2 - y1) / (x2 - x1)
Slope = (465 - 105) / (10 - 2)
Slope = 360 / 8
Slope = 45
Daily rate = $45
Using the slope intercept relation :
y = mx + c
m = slope, c = intercept
105 = 45x + c
105 = 45(2) + c
105 = 90 + c
105 - 90 = c
15 = c
Pricing plan :
y = 45x + 15
Answer is 45 because if you divide 90/2 it equal 45
C=45d+15

2 3/5 is what percent of 20
Answer:
13%
Step-by-step explanation:
Answer:
Hello There!!
Step-by-step explanation:
The answer is 13% as you convert 2 3/5 to an improper fraction which is 13/5. Convert this into a decimal which is 2.6 . 2.6 ÷20=0.13 ×100 (to get it as a fraction) which equals 13%.
hope this helps,have a great day!!

ILL MARK BRAINLEIST.
Find the Pattern If the pattern continued, how many orange blocks would be in the next figure? Can you write a linear function (y = mx + b) that gives the number of blocks for any figure?
Answer:
Part A
aₙ = 5 + (n - 1)·4
Part B
y = 4·x + 1
Step-by-step explanation:
Part A
The number of orange blocks in Figure 1 = 5
The number of orange blocks in Figure 2 = 9
The number of orange blocks in Figure 3 = 13
Therefore, we get;
5, 9, 13, ... with increments of 4
The first term, a = 5
The common difference, d = 4
The sequence is in the form of an Arithmetic Progression, therefore, we have;
aₙ = 5 + (n - 1)·4
Where;
n = The Figure number
When n = 3, we have;
a₃ = 5 + (3 - 1) × 4 = 12 orange blocks as in the diagram in the question
Part B
To express the number of blocks using the linear function, y = m·x + b, we have;
Let 'x', represent the number of each figure, let 'y' represent the total number of blocks in each figure, let 'd' represent the initial amount of blocks present when x = 0, and let 'm' represent the rate of change of 'y' with each change in 'x'
We note that the rate of change the total number of blocks for each increase in figure number is 4, therefore, we have;
The rate of change, m = 4
∴ y = 4·x + d
When x = 1, y = 5, we get;
5 = 4 × 1 + d
∴ d = 5 - 4 = 1
d = 1
The linear equation that gives the number of blocks is therefore;
y = 4·x + 1.

So you see that it says Find the probability that the sum on the two dice is 4 given that the sum is even. So that means that it would be 2 dices that have rolled a 4 and the equation would be 2×4= 8, So that means that you want to write the answer which is 8 in a fraction, and 8 in a fraction is 8/1

find the measure of the indicated arc
in circle o.
D

O
E
B
mDB = [?]°
Answer:
124°
Step-by-step explanation:
measure of arc DC = 44 because the measure of central angle equals the measure of its arc.
measure of arc CB = 80 because the measure of central angle equals the measure of its arc.
measure of arc DC = measure of arc DC + measure of arc CB
= 44 + 80 = 124°
Can someone please help me with this questions, please help me I really need help please help me.
Answer:
D. A = x² + 44x = 808Step-by-step explanation:
Check if the relationship is linear. Verify the difference between areas.
We can see the difference is not common.
It means we can exclude options B and C.
The remaining options are quadratic (A and D).
Try the last column with option A:
4813 = 45² + 19084813 = 3933FalseVerify the last option:
4813 = 45² + 44*45 + 8084813 = 4813CorrectWe can check and confirm the other columns are correct as well.
Answer:
Solution given:
for 1st

WILL MARK BRAINLIEST PLEASE HELP
Answer:
A = 5 units²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂
d₁ = x + 4 = 1 + 4 = 5
d₂ = 2y - 4 = 2(3) - 4 = 6 - 4 = 2 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 5 units²
Answer:
A= 5m
Step-by-step explanation:
The equation to find the area of a rhombus, when knowing the diagonals, is:
1/2×d1×d2To solve this, we have to find first d1 and d2, which are marked in a parenthesis:
d1= (x+4)m, where x=1d1= 5md1= 5m. Now, let's find d2:
d2= (2y-4)m, and y=3d2= (6-4)md2= 2mKnowing the values of both diameters, we can solve the equation for the area:
A= 1/2×d1×d2A= 1/2×5m×2mA= 1/2×10mA= 5mThe area of the rhombus is 5 meters.

Answer:
a) I donot agree with him because as we see the sequence nicely we will find an interval of 8 between any two terms and 32 and 33 don't match them
Step-by-step explanation:
b) and c) Solution:
Given,
First term (a) = 4
Common difference (d) = 12-4 = 8
Now,
Since, they are in A.P.
nth term = a + (n-1)d
= 4 + 8(n-1)
= 4 + 8n-8
= 8n-4
Again,
1st method for c)
100th term = a + 99d = 4 + 99*8 = 4 + 792 = 796
200th term = a + 199d = 4 + 199*8 = 4 + 1592 = 1596
2nd method for c)
100th term = 8*100 - 4 = 800 - 4 = 796
200th term = 8*200 - 4 = 1600 - 4 = 1596
