Answer:

A(-2,2);B(6,2);C(6,-2);D(-2,-2)

Step-by-step explanation:

If the given figure is dilated by a scale factor of 4, that means the figure will be four times bigger.

We can get the coordinates of the dilated ifigure by using the scale factor on each coordinate.

The given figure has coordinates: A'(-0.5, 0.5), B'(1.5,0.5), C'(1.5, -0.5) and D'(-0.5,-0.5)

So, the dilated coordinates are

A(-2,2);B(6,2);C(6,-2);D(-2,-2)

Maryland had $(62xsquared + x - 4) on mondays she spent $(11x squared - 33) on a pair of gloves how much money did she have left
Anton [14]

Answer:

$( 51x^2 + x + 29).

Step-by-step explanation:

Amount she had left = original amount - amount spent on the gloves

=  62x^2 + x - 4 - (11x^2 - 33)   (note we place the amount spent on gloves in parentheses because we have to subtract the whole amount)

Now we distribute the negative over the parentheses:

= 62x^2 + x - 4 - 11x^2 + 33     ( note - 33 becomes -33*-1 = +33)

Now simplifying like terms:

= 51x^2 + x + 29  (answer).

Can someone help me with this asap please, thanks!
kvv77 [185]

Answer:

Given: r\perp s and t\perp s.

Prove: r\parallel t

Since r\perp s, By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly t\perp s,  it means angles 5, 6, 7 and 8 are 90 degree.

We can say that,

\angle 1\cong \angle 5, \angle 2\cong \angle 6, \angle 3\cong \angle 7 and \angle 4\cong \angle 8

From figure it is noticed that the angle 1 and 5 are corresponding angles.

If two parallel lines are intersected by a transversal, then the corresponding angles are equal.

Since corresponding angles are congruent, therefore the line must be parallel to each other.

Hence proved that r\parallel t.

Sample size: A researcher is trying to decide how many people to survey. Which of the following sample sizes will result in a co
oksian1 [2.3K]

Answer:

Step-by-step explanation:

Given that a researcher is trying to decide how many people to survey.

We have confidence intervals are intervals with middle value as the mean and on either side margin of error.

Confidence interval = Mean ± Margin of error

Thus confidence interval width depends on margin of error.

Margin of error = Critical value *\frac{\sigma}{\sqrt{n} }

Thus for the same confidence level and std deviation we find margin of error is inversely proportional to square root of sample size.

Hence for small n we get wide intervals.

So if sample size = 300, the researcher will get wider confidence interval
