The statistical test would be a Z-test for the difference between the proportions.

The Z test is a parametric procedure that is used on data that is dispersed in a normal fashion. For testing hypotheses, the z test can be used on one sample, two samples, or proportions. When the population variance is known, it analyzes if the means of two big groups are dissimilar.

We have:

In a recent poll among 500 students, it was found that 60% of women and 68% of men eat meals on campus at least 3 times a week.

From the above data and the definition of the Z-test, the statistical test would be a Z-test for the difference between the proportions.

Thus, the statistical test would be a Z-test for the difference between the proportions.

The equation that can be solved when the given quadratic formula is used is c. 3x² + 8x − 10 = -8.

The given quadratic equation is:

x = (-8 ± √(8² - 4(3)(-2))) / 2 (3)

Rewriting the quadratic equation in option C gives:
3x² + 8x − 2 = 0

Seeing as a quadratic equation takes the form:

x = (-b ± √(b² - 4(a)(c))) / 2 (a)

The formula becomes:

x = (-8 ± √(8² - 4(3)(-2))) / 2 (3) which is the given quadratic formula.

In conclusion, option C is correct.

Answer:

Also the quadrilateral shown is a rhombus

Step-by-step explanation:

The length of the SM parallelogram when the length of the rectangle is 15 cm and width is 8 cm is 8/5 units.

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of the rectangle and (b) is the width of the rectangle

The length of the rectangle is 15 cm and width is 8 cm. Thus, the area of it is,

[tex]A=15\times8\\A=120\rm\; cm^2[/tex]

All three parts has equal area. Thus, the area of parallelogram NCMA is,

[tex]A_p=\dfrac{120}{3}\\A_p=40\rm\; cm^2[/tex]

MN is the height of the parallelogram. Thus,

[tex]A_p=h\times AS\\40=h\times15\\h=\dfrac{40}{15}\\h=\dfrac{8}{5}[/tex]

Thus, the length of the Sm parallelogram when the length of the rectangle is 15 cm and width is 8 cm is 8/5 units.

Step-by-step explanation:

unknown angle = given angle - 360 because a full circle is 360°

so unknown angle "n" = 360 - 324 = 36

Answer:

1.cannot

2.can

3.cannot

4.can

Step-by-step explanation:

it's actually quite simple. if the angles add up to 180°, it is a triangle. so if they don't, then its not a triangle.

21+28+41= 90 -> not a triangle

65+45+70=180 -> triangle

48+52+54=154 -> not a triangle

16+40+124=180 -> triangle

15. t=97/5

16. x=5/2

17. x=-70/3

Answer:

s = 132 square cm

Step-by-step explanation:

s = area of base + area of lateral faces

Area of base (triangle)

A = 1/2bh

A = 1/2(3)(4)

A = 1/2(12)

A = 6

There are two bases (triangles), so multiply the answer by 2.

6 x 2 = 12

Area of lateral faces (3 rectangles)

First rectangle:

A = lw

A = 5(10)

A = 50

Second rectangle:

A = lw

A = 4(10)

A = 40

Third rectangle:

A = lw

A = 3(10)

A = 30

Add all the areas together.

s = 12 + 30 + 40 + 50

s = 132 square cm

Answer:

1 ft

Step-by-step explanation:

scale: 5 in. = 8 ft

Back wall scale measurement: 15 in.

Back wall real measurement: 15 in. × 8 ft / 5 in. = 24 ft

Each workstation measures 4 ft.

5 workstations measure 5 × 4 ft = 20 ft

24 ft - 20 ft = 4 ft

When you place 5 workstations, the outer two will be at the ends of the 24-ft wall. There will be 4 spaces between the workstations.

4 ft / 4 = 1 ft

Answer: 1 ft

Plato/Edmentum

Step-by-step explanation:

since he was already on time on the first day, the question is reduced to the probability of being on time on exactly one of the next 2 days.

the probability to be on time on exactly one day means to be on time on one day and to be late on the other.

the probability to be late is the opposite of the probability to be on time, so

1 - 0.7 = 0.3

so, the probability for this combined event for one of the day combinations is

0.7 × 0.3 = 0.21

how many day combinations (1 day on time, the other late) can we have ? 2 (either on time on the first and late on the second, or late on the first and on time on the second).

so, we need to multiply this with the basic probability and get

0.21 × 2 = 0.42

so, b. is the right answer.

And XZ=1/2XY

XZ be x

Now

XZ=21.4units

Answer:

XZ = 21.4 units

Step-by-step explanation:

If  ΔXYZ  is an isosceles triangle then XY = ZY

(the dashes on the line segments indicate they are of equal measure)

If XZ = ¹/₂XY then

⇒ 2XZ = XY = ZY

If the perimeter is 107 units:

⇒ Perimeter of ΔXYZ = XY + ZY + XZ

⇒ 107 = 2XZ + 2XZ + XZ

⇒ 107 = 5XZ

⇒ XZ = 107 ÷ 5

⇒ XZ = 21.4 units

With ∠C=∠F, ΔABC and ΔDEF are congruent by AAS congruence. Therefore, option A is the correct answer.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Consider ΔABC and ΔDEF,

Here, ∠B=∠E=50°

AB=DE=10 units

With ∠C=∠F

So, by AAS congruence theorem ΔABC and ΔDEF are congruent

Therefore, option A is the correct answer.
