What is the value of x​

Mathematics
1 answer:
Leokris [45]2 years ago
5 0

Answer:

X = 40°

Step-by-step explanation:

The sum of the interior angles in a triangle is 180°. This means that:

2X + 35 + 2X - 15 = 180° - we can simplify this

4X + 20 = 180° - now, subtract 20 from both sides

4X = 160° - finally, divide both sides by 4

X = 160 ÷ 4 = 40°

X = 40°

Hope this helps!

Use the table.
zubka84 [21]

Solution:

The table which is about kind of jeans and it's color is

Style       Color  

regular      light blue  

loose fit    indigo  

boot cut     washed  

slim fit       black

 slim fit     blue

(a) A regular can be chosen out of five  colors, A loose fit can also be chosen in five colors,Similarly a boot cut as well as slim fit can also  be chosen out of five colors.

If you consider this as a relation , total number of relation that is total jeans =  1×5 + 1×5 +1×5+1×5= 20 Jeans = 10 Pairs of jeans(Possible)

(b)  Total number of jeans , if i have one pair of jeans of each possible style and color = As there are 5 colors and 4 styles , the jeans are in pair = 5×4×2=40

Number of Black color jeans = 2× black color in  4 styles= 2×4=8

Probability of an event = \frac{\text{Total possible outcome}}{\text{Total favorable outcome}}

Probability of choosing a pair of black jeans at random=\frac{8}{40}=\frac{1}{5}

Population A and Population B both have a mean height of 70.0 inches with an SD of 6.0. A random sample of 50 people is picked f
Alex

Answer:

Sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.

Step-by-step explanation:

To yield a more accurate estimate of the population mean, margin of error should be minimized.

margin of error (ME) of the mean can be calculated using the formula

ME=\frac{z*s}{\sqrt{N} } where

  • z is the corresponding statistic in the given confidence level(z-score or t-score)
  • s is the standard deviation of the sample (or of the population if it is known)
  • N is the sample size

for a given confidence level, and the same standard deviation, as the sample size increases, margin of error decreases.

Thus, random sample of 50 people from population A, has smaller margin of error than the sample of 20 people from population B.

Therefore, sample mean from population A has probably more accurate estimate of its population mean than the sample mean from population B.
