Answer:
x and y
Step-by-step explanation:
Those are variables that could be any number. The integers are considered to be coefficients.
The following results are for two independent samples taken from the two populations. Sample 1 Sample 2 n1 = 40 n2 = 50 x1 = 25.7 x2 = 22.8 σ1 = 5.3 σ2 = 6 (a) What is the value of the test statistic? (Round your answer to two decimal places.)
Answer:
the value of the test statistic is 2.43
Step-by-step explanation:
The computation of the value of the test statistic is shown below:
[tex]z = \frac{\bar x _1 - \bar x _2}{\sqrt{\frac{\sigma_1^2 + \sigma_2^2}{n_1 + n_2} } }[/tex]
[tex]= \frac{25.7 - 22.8}{\sqrt{\frac{5.3^2}{40}+ \frac{6^2}{50} } }\\\\= \frac{25.7 - 22.8}{\sqrt{0.70225 + 0.72} }\\\\= \frac{2.9}{1.19258}[/tex]
= 2.43
Hence, the value of the test statistic is 2.43
The same would be considered and relevant by applying the above formula
All of the dimensions of the solid are multiplied by a factor of k=10 how many times greater is the surface area of the new solid? How many times greater is the volume of the new solid?
URGENT PLS PLS PLSPLSOWSOQDNPN
Step-by-step explanation:
The surface area increases by 100
if x y and z are side lengths and it is a rectangle.
Then finding the surface area would normally be 2xy+2yz+2xz
But then increasing each side length by a factor of 10 means multiplying it together
2x(10)y(10)+2y(10)z(10)+2x(10)z(10)
200xy+200yz+200xz and that is 100 times greater than the normal surface area.
Volume:
(x)(y)(z)=normal volume
x(10)y(10)z(10)=increased value
1000xyz=new volume
that is 1000 times greater than the previous volume
Hope that helps :)

Answer:
[tex] \large \boxed{y = - \frac{2}{3} x + 2}[/tex]
Step-by-step explanation:
both slopes multiply each others must equal to -1 for perpendicular.
[tex] \large{m_1m_2 = - 1}[/tex]
Let m1 = 3/2
[tex] \large{ \frac{3}{2} m_2 = - 1} \\ \large{3m_2 = - 2} \\ \large{m_2 = - \frac{2}{3} }[/tex]
Therefore -2/3 is perpendicular to 3/2. Because the line passes through (6,-2)
[tex] \large{y - y_1 = m(x - x_1)}[/tex]
Given (x1, y1) = ordered pair
Therefore (x1, y1) = (6,-2)
and m = - 2/3
[tex] \large{y + 2 = - \frac{2}{3} (x - 6)}[/tex]
Write in slope-intercept form.
[tex] \large{y = - \frac{2}{3} x + 4 - 2} \\ \large{y = - \frac{2}{3}x + 2}[/tex]

That’s just your millennial snowflake brain being unable to comprehend real work. My grandpa lost both his thumbs to frostbite while walking 29.67 kilomiles to school in 10 feet of snow in the summer uphill both ways and he could still wield any tool known to man. And he did so for 83 and a half years until they forced him to retire because he was making all the other workers look like pansies. When he was told he was being forced to retire, he marched into the CEO’s office and declared “I’d rather be dead than a deadbeat.” Then he dropped dead on the spot. Now that’s loyalty!

What is the volume of a rectangular crystal with a length (1) of 2.2 cm, a width (w) of 2 cm, and a height
(h) of 1.8 cm?
Answer:
7.92 cm^3
Step-by-step explanation:
To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

Answer:
Perimeter of base = 18 ft
Height = 7 ft
Base area = 12ft²
SA= 150 ft² *
Step-by-step explanation:
Perimeter of base = 8+5+5=18 ft
Height = 7 ft
Base area = 1/2x8x3=12ft²
SA= (8x7)+(12+12)+2(5x7)=56+24+70=150 ft²
*There are several different way to figure out the surface area, so I’m not sure exactly how they want it displayed. 150 is the answer though. Plus, I think there was supposed to be an addition sign between the first two parentheses.
write 9/6 as a mixed number
9/6 can be written as the mixed number 1 1/2.
This means there is 1 whole unit and 1/2 (or half) remaining.
To write 9/6 as a mixed number, we need to divide the numerator (9) by the denominator (6).
When we divide 9 by 6, we get a quotient of 1 and a remainder of 3.
So, 9 divided by 6 is 1 with a remainder of 3.
We can express this as a mixed number by combining the whole number and the fraction:
1 + 3/6
However, the fraction 3/6 can be simplified. Both the numerator and denominator share a common factor of 3.
Dividing both by 3 gives us:
1 + 1/2
Now, we have the whole number part (1) and the proper fraction part (1/2).
Putting it all together, the mixed number representing 9/6 is: 1 1/2
Therefore, 9/6 can be written as the mixed number 1 1/2.
This means there is 1 whole unit and 1/2 (or half) remaining.
So, 9/6 as a mixed number is 1 1/2.

What is the remainder of (x4 - 2x2 + x - 3) ÷ (x - 1)
Step-by-step explanation:
First simplify the parentheses. [tex]4x-2x^2+x-3=-2x^2+5x-3[/tex], and [tex]x-1[/tex] can't be simplified, so the equation has now been simplified to [tex]\frac{-2x^2+5x-3}{x-1}[/tex]. The equation can be divided to equal [tex]-2x+3[/tex], so I'm guessing either there is no remainder or the 3 is the remainder.
Hope this helps!
