WILL GIVE BRAINLIEST! DUE TODAY! WILL GIVE EVERYTHING GOOD!!! HELPP!!! I REALLY NEED HELP ON THIS ONE!!!!
PtichkaEL [24]

Answer:

So its pretty simple

The table provided the Xs so you can just substitute the x in the eqaution becuase the eqaution gives you Y and your looking for Y.

For the first one

-3/4*-16+3=y

12+3=15

So Y is 15

DO the same for the others

Also I think your rate of change is wrong, I think it’s -3/4 but your choice really, I might be wrong

Hello,

As \vec{i}*\vec{j}=0\\
\vec{v}*\vec{w}=\sqrt{2}*\vec{i}*4*\vec{j}=4*\sqrt{2}*0=0
Vectors are orthogonal.

Answer:

The value of x is 66.

Step-by-step explanation:

The median of a data set is the term that separates the lower half of the set from the upper half.

In a set with even cardinality, the median is given by the mean of it's two middle terms.

In this question:

Cardinality: 8

Middle terms: 4th and 5th, which are x - 5 and x + 1.

The median is 64.

This means that:

\frac{x - 5 + x + 1}{2} = 64

2x - 4 = 128

2x = 132

x = \frac{132}{2}

x = 66

The value of x is 66.
