Step-by-step explanation:
Just input the first 4 values for x:
(0, y)
y = 4x
y = 4(0)
y = 0
(1, y)
y = 4x
y = 4(1)
y = 4
(2, y)
y = 4x
y = 4(2)
y = 8

4/5x+5=9 solve for x please i have 8 questions left!!!!!!!!!!!
Answer:
x= 5
Step-by-step explanation:
You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.
One interior angle of a triangle is 60°. The other angle measures are x° and yº. Which of the following could be the values of
x and y? Select all that apply. X = 60, y = 60
X = 100, y = 20
X = 40, y = 80. x=50, y = 90
X = 45, y = 45
Answer:
x=60, y= 60
x=100, y= 20
x=40, y=80
Step-by-step explanation:
Triangles add up to 180 degrees. The ones above added to 60 equal 180.
60+60+60=180
100+20+60=180
40+80+60=180
Hope this helps! :)
I need help with the first question pls
Answer:
67.5 feet
Step-by-step explanation:
If 1 inch = 9 feet, and the model is 7.5 inches,
you just need to do 7.5 • 9 = 67.5 feet.
OR
7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5
63 + 4.5 = 67.5
*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet
If the speed of sound is 1230 km/h, calculate the speed of sound in metres per second.
Write down your answer correct to the nearest metre.
Answer:
342 m/s
Step-by-step explanation:
1230x 1000 = 1230000
1230000 / 60 = 20500
20500 / 60 = 341.666 = 342

Step-by-step explanation:
The results of a series of surveys revealed a population with a mean of 4.73 and a standard deviation of 0.865. If each survey has a sample size of 200, which value falls within the interval where 95% of the sample means occur? A. 4.88 B. 4.63 C. 4.91 D. 4.55
Answer:
4.63
Please give me brainliest, I really need it.
The value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.
What is a confidence interval for population standard deviation?It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.
The formula for finding the confidence interval for population standard deviation as follows:
[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]
Where s is the standard deviation.
n is the sample size.
[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex] are the constant based on the Chi-Square distribution table.
α is the significance level.
σ is the confidence interval for population standard deviation.
Calculating the confidence interval for population standard deviation:
We know significance level = 1 - confidence level
It is given that:
Mean of the population x = 4.73
Standard deviation s = 0.865
Sample size n = 200
The interval where 95% of the sample means occur:
Lower limit = 4.73 - 0.865/√200
Lower limit = 4.66
Upper limit = 4.73 + 0.865/√200
Upper limit = 4.791
The interval = (4.66, 4.791)
Thus, the value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.

Roger buys flowers to plant around his trees. 3/8 of the flowers are red. 1/3 of the flowers are pink. The rest of the flowers are white. Which of the following explains how to find the fraction of flowers that are white? A) Add 3/8 and 1, then subtract 1/3 from the sum. B) Add 3/8 and 1/3, then subtract the sum from 1. C) subtract 1/3 from 1, then add 3/8 to that difference. D) Subtract 1/3 from 3/8, then subtract the difference from 1.
PART B:
What fraction of the flowers are red or pink?
A) 4/11 B) 5/8 C) 17/24 D) 2/3
PART C:
What fraction of the flowers are white?
A) 7/24 B) 1/3 C) 3/8 D) 7/11
Answer:b, c, a
Step-by-step explanation:
Given
[tex]\frac{3}{8}[/tex] of the flowers are red
[tex]\frac{1}{3}[/tex] of the flowers are white
to get the white flowers, add the two fraction and subtract them from 1
fraction of white flowers
Part- B
Fraction of flower red or Pink
[tex]\Rightarrow \dfrac{3}{8}+\dfrac{1}{3}=\dfrac{17}{24}[/tex]
Part-C
fraction of flowers that are white
[tex]\Rightarrow 1-\dfrac{3}{8}-\dfrac{1}{3}\\\\\Rightarrow 1-\dfrac{9+8}{24}\\\\\Rightarrow 1-\dfrac{17}{24}=\dfrac{7}{24}[/tex]
the perimeter of a rectangle is (10x2).if it's width is (2x-1),which expression represents the length
a.5x-2
b.3x+2
c.8x+3
d.12x+1
Answer: b. 3x + 2
Step-by-step explanation:
2l + 2w = p
2l + 2(2x - 1) = 10x + 2
2l + 4x - 2 = 10x + 2
2l = 6x + 4
l = 3x + 2
One leg of a right triangle is 3 cm and the hypotenuse is 5 cm. Joni found the length of the other leg by evaluating √32 + 52. What error did she make? How would you help her correct her error so she is less likely to make the same error in the future?
Answer: See explanation
Step-by-step explanation:
We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:
x² + 3² = 5²
x² + 9 = 25
x² = 25 - 9
x² = 16
x = ✓16
x = 4cm
The other leg is 4cm
Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.

need help with trig. find the value of variable to the nearest tenth
Answer:
x = 10.43
Step-by-step explanation:
use tan:
⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 41 = [tex]\frac{12}{x}[/tex]
tan of 41 is 0.869
⇒ 0.869 = [tex]\frac{12}{x}[/tex]
multiply each side by 12
⇒ 0.869 x 12 =[tex]\frac{12}{x}[/tex] x 12
x = 10.43

17x31=? lol ill give 20 dollarsto who ever gets this first
Please answer!!! I’ll make brainliest
Answer:
10.3
Step-by-step explanation:
The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.
[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]
We find the square root of both sides to find the value of c.
10.295 ≈ c
Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3
