A manufacturer of salad dressings uses machines to dispense liquid ingredients into bottles that move along a filling line. The machine that dispenses dressing is working properly when 8 ounces are dispensed. The standard deviation of the process is 0.15 ounces. A sample of 48 bottles is selected periodically, and the filling line is stopped if there is evidence that the mean amount dispensed is different from 8 ounces. Suppose that the mean amount dispensed in a particular sample of 48 bottles is 7.983 ounces. Calculate the P-Value.

Suppose Tetha = alpha = 26°

Then ;

$\tan( \alpha ) = (y)/(x) \n$

$\tan(26°) = (8)/(x) \n$

$0.487 = (8)/(x) \n$

Multiply sides by x

$0.487x = 8$

Divide sides by 0.487

$x = (8)/(0.487) \n$

$x = 16.427$

$x≈ 16.43$

The similar triangle is the image of the bigger triangle after a sequence of transformations. What is the value of x?

Answers

Answer:

The value of x is: 2.5 units

Step-by-step explanation:

Two triangles are said to be similar if the ratio of the corresponding sides of the two triangles are equal.

i.e. if two triangles ΔABC and ΔDEF are similar such that the sides of the triangle ABC are a, b and c and the corresponding sides in ΔDEF are d,e and f respectively then we have:

$(a)/(d)=(b)/(e)=(c)/(f)$

Here we have the base length of the orange i.e. the quadrant above the x-axis as: 8 units

and the base length of the similar triangle i.e. triangle below x-axis as: 4 units.

i.e. we have: a=8 and d=4

and b=5 and e=x

Hence, we have:

$(5)/(x)=(8)/(4)$

i.e.

$x=(5* 4)/(8)$

Hence, we have:

$x=2.5$

We have
$(5)/(x) = (8)/(4) \: so \n 20 = 8x \: so \n x = (20)/(8) = (10)/(4) = (5)/(2) = 2 (1)/(2)$

The amount is 2.88 is ( percent of what price?

Answers

Answer:

Discount = Original Price x Discount %/100

Discount = 2.88 × 1/100

Discount = 2.88 x 0.01

You save = $0.03

Final Price = Original Price - Discount

Final Price = 2.88 - 0.0288

Final Price = $2.85

Step-by-step explanation:

A line segment is dilated by a scale factor of 2 centered at a point not on the line segment. Which statement regarding the relationshipbetween the given line segment and its image is true?
A The line segments are parallel, and the image is twice the length of the given line segment.
B. The line segments are parallel, and the image is one-half of the length of the given line segment.
C. The line segments are perpendicular, and the image is twice the length of the given line segment.
DD The line segments are perpendicular, and the image is one-half of the length of the given line segment.

Answer:

A The line segments are parallel, and the image is twice the length of the given line segment.

Step-by-step explanation:

Dilation by a factor of 2 means any measure of the image is 2 times the corresponding measure of the original.

Dilation does not change any orientations, so the image will have the same orientation with respect to the origin, axes, or any other line segments. That means the dilated segment is parallel to the original. (If the center of dilation is on the original line segment, the dilated segment will overlay the original segment. That is specifically not the case here.)
