Answer:
42
Step-by-step explanation:
If y equals 3, then substitute y for 3, getting 45 - 3.
45 - 3 is 42, so that's your answer.

Which of the following represents
this number in scientific notation?
-0.904
A. 9.04 • 10^-1
B. -9.04 • 10^1
C. -9.04 • 10^-1
D. -9.04 • 10^-3
Answer:
The correct option is (c).
Step-by-step explanation:
The given number is -0.904.
We need to represent the number in scientific notation.
Any number can be written in scientific notation as follows :
[tex]a\times 10^b[/tex]
Where
a is a real number and b is an integer
We can write it as follows :
[tex]-0.904=-9.04\times 10^{-1}[/tex]
Hence, the correct option is (c).

Wil following three angles for a triangle? 30 degrees 60 degrees 90 degrees
Please help i don’t know if I’m doing this right
Answer:
x = 41
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 40^2 = c^2
81 + 1600 = c^2
c^2 = 1681
c = 41
Step-by-step explanation:
In order to find the hypotenuse of a right triangle, you must remember the theorem:
a² + b² = c².
40 to the second power is 1600, and 9 to the second power is 81.
Add these together for a total of 1681, but you're not done yet. We need to find what multiplied by itself equals 1681, since c is to the second power.
The square root is 41, so x is 41.
2 + ( x +24) + (2+x) = 40 find the value of x

Step-by-step explanation:
Music streaming services are the most popular way to listen to music. Data gathered over the last 12 months show Apple Music was used by an average of 1.73 million households with a sample standard deviation of 0.46 million family units. Over the same 12 months Spotify was used by an average of 2.17 million families with a sample standard deviation of 0.33 million. Assume the population standard deviations are not the same. Using a significance level of 0.01, test the hypothesis of no difference in the mean number of households picking either service.
Answer:
There is enough statistical evidence to suggest that there is no difference between the mean number of households picking either service
Step-by-step explanation:
The parameters of the music streaming service are;
The average number of households using Apple Music, [tex]\overline {X}_1[/tex] = 1.73 million
The standard deviation, σ₁² = 0.46 million
The average number of households using Spotify, [tex]\overline {X}_2[/tex] = 2.17 million
The standard deviation, σ₂² = 0.33 million
The significance level = 0.01
Hypothesis testing with different population standard deviation
[tex]Z = \dfrac{\overline {X}_1 - \overline {X}_2}{\sqrt{\dfrac{\sigma_1^2}{n_1} +\dfrac{\sigma_2^2}{n_2}} }[/tex]
H₀: [tex]\overline {X}_1[/tex] ≠ [tex]\overline {X}_2[/tex]
H₁: [tex]\overline {X}_1[/tex] = [tex]\overline {X}_2[/tex]
[tex]Z = \dfrac{1.73- 2.17}{\sqrt{\dfrac{0.46^2}{12} +\dfrac{0.33^2}{12}} } = -2.6923[/tex]
p-value for the test statistic = 2 × P(Z <-2.6923) = 2 × 0.00357 = 0.00714
Therefore, the p-value is less than the significance level, and it is therefore unlikely that the result will be observed under the null hypothesis
We therefore reject the null hypothesis and there is enough statistical evidence to suggest that there is no difference between the mean number of households picking either service
If 1=3. 2=3. 3=5. 4=4. 5=4. Then, 6=?
Question: If 1=3. 2=3. 3=5. 4=4. 5=4. Then, 6=?
Answer: Like wise, If 1=3.2=3 3=5 4=4 5=4 Than 6=3
Because of six. Six split in two is 3 therefore 6=3

State a cubic or quartic function with the least degree possible in intercept form for the given graph. Assume that all x-intercepts are integers, and that the constant factor a is either 1 or −1.
Enter the correct value in the box to answer the question.
y= ?
Answer:
y = [tex]-x^{3} - 2x^{2} + 5x + 6[/tex]
Step-by-step explanation:
The function will be cubic. The x-intercepts are -4, -1, and 2
The constant factor is -1 because the graph falls on the right. So,
y = -(x + 4)(x + 1)(x - 2)
y = -[tex]x^{3} -2x^{2} + 5x +6[/tex]

Answer:
y=4x bc each one is 4 so for one box it cost $4
Answer:
The expression will be y = 4x.
Step-by-step explanation:
First, we have to form expressions for number of boxes and total amount she earn :
Let x be the number of boxes,
Let y be the total amount,
Given that the costs of each box is $4 so in order to find the total amount, you have to multiply the number of boxes by 4 :

Five houses in the neighborhood sold this month for the following prices:
$328,000, $297,500, $415,000, $389,000, $345,000.
The house with the highest selling price sold for how much more than the median selling price?
Answer:
70,000
Step-by-step explanation:
Median= 345,000
Higest selling house= 415,000
415,000-345,000= 70,000

Find the area of the triangle using Pythagorean theorem
Answer:
48
Step-by-step explanation:
Remark
Use a^2 + b^2 = c^2 to solve for the height.
Givens
c = 10
b = 6
h = ?
Solution
b^2 + h^2 = c^2
6^2 + h^2 = 10^2
36 + h^2 = 100 Subtract 36
h^2 = 100 - 36
h^2 = 64 Take the square root of both sides
sqrt(h^2) = sqrt(64)
h = 8
The height = 8
Area = 1/2 * b * h
Area = 1/2 *12 * 8
Area = 48
