Answer:
T-shirt : £11
Hat : £7
Step-by-step explanation:
Think of T-shirts as T
and Hats as H
5t + h = 62
2t + h = 29
we then subtract them both to cancel out h
3t = (62-29) = 33
now we divide 33 by 3 to find one t
33/3 = 11
so one t shirt is £11.00
now we substitute it back into the equation
2t ( 2x11 ) = 22
22 +h = 29
29 - 22 = 7

Which equation of the least squares regression line most closely matches the data set?
yˆ=−0.31x+37.3
yˆ=−0.09x+11.5
yˆ=−10.1x+118.8
yˆ=−2.3x+97.9
Answer:
I can confirm that the answer above is correct.
Step-by-step explanation:
Hope this helps. :D
The equation of the least squares regression line which is most closely matches the data set is yˆ=−10.1x+118.8
What is linear regression?Linear regression is a type of regression which is used to model the data having linear relationship between the variables. The regression line can be given as,
[tex]\hat y=bX+a[/tex]
The data given in the problem is,
x 2 4 6 8 10y 100 83 50 35 23Mean of x and y values,
[tex]\mu_x=\dfrac{2 +4 +6 +8 +10}{5}=6\\\mu_y=\dfrac{100 +83 +50 +35 +23}{5}=58.2[/tex]
Here, in this data points, the sum of the squares is 40 and sum of the products is -404. The value of b is,
[tex]b=\dfrac{-404}{40}\\b=-10.1[/tex]
The value of a is,
[tex]a=58.2-(10.1\times6)\\a=118.8[/tex]
Put the values in the above equation,
[tex]\hat y=-10.1X+118.8a[/tex]
Thus, the equation of the least squares regression line which is most closely matches the data set is yˆ=−10.1x+118.8

Which equation illustrates dividing out a common factor as the first step to solve the equation 2 x + 4 = 6 x + 2 ? A. 2 ( x + 2 ) = 2 ( 3 x + 1 ) B. 2 x 2 + 2 2 = 6 x 2 + 2 2 C. 2 x 2 + 4 = 6 x 2 + 2 D. 2 x + 4 2 = 6 x + 2 2
Answer:
Step-by-step explanation:
2x + 4 = 6x + 2
Bringing like terms on one side
4 - 2 = 6x - 4x
2 = 2x
2/2 = x

8. Let angle A and angle B be acute angles in two right triangles. Calculate the angle and
round to the nearest tenth of a degree.
a. sin A = 0.87
b. cos B = 0.15
9514 1404 393
Answer:
a. 60.5°
b. 81.4°
Step-by-step explanation:
Inverse functions are used to find the angle value for a given trig function value.
a) arcsin(0.87) ≈ 60.5°
b) arccos(0.15) ≈ 81.4°
__
On many calculators, these functions are accessed using a 2nd or Shift key. They are often labeled as sin⁻¹ and cos⁻¹. The calculator will have a mode setting that needs to be set to "Degrees" if you don't want the angle in radians or grads.

Rewrite each expression by combining like terms.
13p - 4p + 6q
Answer:
You answer would be 15p
Step-by-step explanation:
13p - 4p + 6p
9p + 6p
15p
Answer:
9p + 6q
Step-by-step explanation:
Rewrite each expression
Combine like terms
13p - 4p + 6q
_____________________
When we have like terms, we can only add the ones that have the same symbols as endings, such as variables, exponents, etc. Therefore :
Add "p" values together :
13p - 4p
9p.
Now rewrite the expression, we cannot combine like terms with "p" and "q" because they are not the same variable :
9p + 6q
