X+4=y=-2x-2
x+4=-2x-2
add 2x to both side
3x+4=-2
minus 4 both sides
3x=-6
divide 3
x=-2

sub back
y=x+4
y=-2+4
y=2

A particular fruit's weights are normally distributed, with a mean of 446 grams and a standard deviation of 17 grams. If a fruit

LekaFEV [45]

Answer:

The weight corresponding to which weight will be larger than 14% of times equals 427.635 grams.

Step-by-step explanation:

We need to find the value of weight that corresponds to 14% of area under the normal distribution curve

It is given that

$\overline{X}=446\\\\\sigma =17$

Using standard normal distribution tables we find value of Z corresponding to 14% of the area as -1.080

Thus using the standard equation

$Z=\frac{X-\overline{X}}{\sigma }\\\\X=\sigma \times Z+\overline{X}\\\\\therefore X=427.635grams$
