A student was performing an experiment that compared a new protein food to the old food for goldfish. He found the mean weight g

ain for the new food to be 12.8 grams with a standard deviation of 3.5 grams. Later he realized that the scale was out of calibration by 1.5 grams (meaning that the scale weighted items 1.5 grams too much). What should the mean and standard deviation be for the new food

Answer:

Mean = 11.3 grams

Standard Deviation = 3.5 grams

Step-by-step explanation:

Mean is affected by change of origin but standard deviation is not affected. Hence the scale weighed items 1.5 grams affect only the mean not standard deviation. Hence, the mean for new food item is 12.8 - 1.5 = 11.3 grams as weight gain by 1.5 gram due to wrong calibration and the standard deviation remains the same as 3.5 grams.

Special Lenses For Special Effects. ... These specialty lenses may be designed with movable focal planes for amazing depth of field, or built to focus extremely close to tiny subjects for macro enlargements, or even to produce a specific type of soft focus that's flattering for portraits

The meaning of photo editing is the act of altering an image, simply put. But that’s oversimplifying a subject which is quite complex.

For example, some photo editing techniques are done manually, while others are conducted through automated software. Some photo editing is even done offline, on actual photographs, posters or other printed collateral.

Other terms for photo editing:

Image editing

Post-processing

Image/photo manipulation

Photoshopping

Image/photo enhancement

Explanation:

so they both are alike because they can both be used to edit photos and both are great to use

A trapezoid has a base of two and six and an area of 24 square units. What is the height?
Nezavi [6.7K]

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=&\stackrel{bases}{parallel}\\ &sides\\ h=&height\\ \cline{1-2} a=&2\\ b=&6\\ A=&24 \end{cases}\implies 24=\cfrac{h(2+6)}{2}\implies 24=\cfrac{h(8)}{2} \\\\\\ 24=4h\implies \cfrac{24}{4}=h\implies 6=h

Answer:

m<10 = 92°

m<5 = 106° (I think because of correspondence)

m<8 =92°

m<14 = 74°

m<3 = 106°

<1 and <4 are corresponding angles

<2 and <3 are same side interior angles

<3 and <4 are vertical angles

<4 a d <6 are Alt. Interior Angles
