Just find a common denominator and find the smallest number that goes into it, which in this case it is 29, so
1/29+6/29+12/29=19/29
Answer:
The 90% confidence interval would be given by (63.330;81.070)
Step-by-step explanation:
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let put some notation
x=left arm , y = right arm
x: 175 169 182 146 144
y: 102 101 94 79 79
Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13

What do you want me to find?
The sum of the numbers 8 × 10⁶ and 7.92 × 10⁹ in the form of scientific notation will be 7.928 × 10⁹.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression is given below.
8 × 10⁶ and 7.92 × 10⁹
The addition of both terms 8 × 10⁶ and 7.92 × 10⁹ will be
⇒ 8 × 10⁶ + 7.92 × 10⁹
⇒ 8 × 10⁶ + 7920 × 10⁶
⇒ 7928 × 10⁶
⇒ 7.928 × 10⁹
The sum of the numbers 8 × 10⁶ and 7.92 × 10⁹ in the form of scientific notation will be 7.928 × 10⁹.

To find the x intercept, sub in 0 for y and solve for x
y + 12 = 3(x - 9)
0 + 12 = 3x - 27
12 = 3x - 27
12 + 27 = 3x
39 = 3x
39/3 = x
13 = x.....so ur x int is 13 or (13,0) <==
and if u wanted to find the y int, u could sub in 0 for x and solve for y
