We wish to study the quality of our production line. We take a random sample of 1000 widgets from our line. A quality rating was

determined for each of the 1000 widgets, and the average quality rating in the sample was 4. The sample standard deviation was 0.5. Also, 6 of the 1000 widgets were found to be defective.
Estimate the average quality rating for widgets from our production line, and include the uncertainty in this estimate in the form, a ± b.

Please help me with this problem TwT. Triangles.
Yanka [14]

Answer:

X = 80°

Step-by-step explanation:

it's an isosceles triangle. you can tell because of the two sides being 14 and the bottom being 18

this means the two bottom angles are the same so the other would also be 50°

Since a triangle has 180° between the three sides, you would subtract 180-100 and get the last angle

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. Determine each segment length in right triangle .
Pani-rosa [81]

The segment length is 14 (square root)2

Given that Triangle ABC is right angle triangle

The vertex marked is B where side AC is the hypotenuse

The side of AC is at Vertex B is 14

The dash segment from vertex B to point D on side AC

Angle BDA is marked right angle .

Angles A and C both marked 45 degrees.

As shown in diagram

Triangle ABC is drawn according to the statement where B is vertex

The side lengths are 14  

Now to find Another side length that is x

So , the equation formed is

x*cos45 = 14

x/√2 = 14

x = 14√2

Hence the length of the segment is 14√2

BlackZzzverrR [31]

Answer:

f(-2) = -6

Step-by-step explanation:

<u>Step 1:  Set x to -2 </u>

f(-2) = -4(-2)^2 + 10

f(-2) = -4(4) + 10

f(-2) = -16 + 10

f(-2) = -6

Answer:  f(-2) = -6
