Answer:

Step-by-step explanation:

Assuming you mean a typical 7-day week... then 378 shipments in one week is the same as 378 shipments in 7 days.

To find a unit rate of shipments per day... simply divide 378 shipments by the 7 days

378 shipments/ 7 days = 54 shipments per day

HELP ME PLEASE HURRY: Wade has claims that quadrilateral ABCD is a square because he has found that all four sides are congruent

RUDIKE [14]

Answer:

At first we should know that:

The properties of the square are:

It has four equal sides.
All angles are right angles or equal to 90º.
The sum of its all angles is 360º
It has two pairs of perpendicular lines.
It has two pairs of parallel lines.

The properties of Rhombus

It has equal four sides.
The opposite sides are of the same length.
It has two acute angles and two obtuse angles.
The sum of its all angles is 360º
It has zero pairs of perpendicular lines.
It has two pairs of parallel lines.

So, Wade is incorrect because the quadrilateral may be Rhombus

And the quadrilateral to be a square, she needs to show that It has two pairs of perpendicular lines.

Komok [63]

Answer: Correct critical value = 2.2622

Step-by-step explanation:

Confidence interval for population mean when population standard deviation is unknown:

$\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}$ , where $\overline{x}$ = sample mean, n= sample size, s= sample standard deviation, $t_{\alpha/2}$ = two-tailed t value.

As per given: n= 10

degree of freedom : df = n-1=9

$\overline{x}=242.6\\\\s=73.33\\\\\alpha=5\%=0.05$

Critical t-value : $t_{\alpha/2,df}=t_{0.05/2,9}=t_{0.025,9}=2.2622$

So, the 95 percent confidence interval estimate for the mean :

$242.6\pm (2.2622)\dfrac{73.33}{\sqrt{10}}\\\\=242.6\pm (2.2622)(23.19)\\\\\approx242.6\pm52.46\\\\=(242.6-52.46,\ 242.6+52.46)\\\\=(190.14,\ 295.06)$

The 95 percent confidence interval estimate for the mean:(190.14, 295.06)

CAN SOMEONE PLEASE HELP ME WITH THIS QUESTION?

Dimas [21]

Answer:

B. More than one quadrilateral exists with the given conditions, and all instances must be isosceles trapezoids.

Step-by-step explanation:

In a parallelogram, adjacent angles are supplementary. They are only congruent if the parallelogram is a rectangle. In this problem, adjacent angles are both congruent and acute. If this were a triangle, it would guarantee the triangle is isosceles.

The fact that opposite angles are supplementary guarantees that the fourth side of the figure is parallel to the base between the acute angles. That makes the figure an isosceles trapezoid. Unless specific angles and side lengths are specified, the description matches any isosceles trapezoid.
