Answer: no it is not but 5/2 is

5/2 = 10/4 = 15/6 = 20/8

= 25/10 = 30/12 = 35/14 = 40/16

= 45/18 = 50/20 = 55/22 = 60/24

= 65/26 = 70/28 = 75/30 = 80/32

= 85/34 = 90/36 = 95/38 = 100/40

= 105/42 = 110/44 = 115/46 = 120/48

= 125/50 = 130/52 = 135/54 = 140/56

= 145/58 = 150/60 = 155/62 = 160/64

= 165/66 = 170/68 = 175/70 = 180/72

= 185/74 = 190/76 = 195/78 = 200/80

= 205/82 = 210/84 = 215/86 = 220/88

= 225/90 = 230/92 = 235/94 = 240/96

= 245/98 = 250/100 = 255/102 = 260/104

= 265/106 = 270/108 = 275/110 = 280/112

= 285/114 = 290/116 = 295/118 = 300/120

= 305/122 = 310/124 = 315/126 = 320/128

= 325/130 = 330/132 = 335/134 = 340/136

= 345/138 = 350/140 = 355/142 = 360/144

= 365/146 = 370/148 = 375/150 = 380/152

= 385/154 = 390/156 = 395/158 = 400/160

= 405/162 = 410/164 = 415/166 = 420/168

= 425/170 = 430/172 = 435/174 = 440/176

= 445/178 = 450/180 = 455/182 = 460/184

= 465/186 = 470/188 = 475/190 = 480/192

= 485/194 = 490/196 = 495/198 = 500/200

Mario is constructing a wall around a rectangular area which will cover a maximum of 60 square feet. The length of the wall will

Feliz [49]

Answer:

$W \le 6$

Step-by-step explanation:

Given

$Area = 60ft^2\ (max)$

$Length = 10ft$

Required

Represent the width as an inequality

First, we represent the area as an inequality.

$Area = 60ft^2\ (max)$

max as used above means less than or equal to.

So, we have:

$Area \le 60$

The area of a rectangle is:

$Area = L * W$

So, we have:

$L * W \le 60$

Substitute 10 for L

$10 * W \le 60$

Divide both sides by 10

$\frac{10 * W}{10} \le \frac{60}{10}$

$W \le \frac{60}{10}$

$W \le 6$

A random sample of 20 houses selected from a city showed that the mean size of these houses is 1880 square feet with a standard

azamat

Answer:

Option C

Step-by-step explanation:

Given that for a random sample of 20 houses selected from a city showed that the mean size of these houses is 1880 square feet with a standard deviation of 320 square feet.

X, the sizes of houses is Normal

Hence sample mean will be normal with

Mean = 1880

and std dev = $\frac{320}{\sqrt{20} } \\=71.5542$

For 90% confidence interval critical value for t with degree of freedom 19 is

1.328

Confidence interval upper bound

= mean + margin of error

= $1880+1.328*71.55\\=1975$

Option C is right

Find the area of the triangle

Misha Larkins [42]

Answer:

=14.69km²

Step-by-step explanation:

We can use the Hero's formula to calculate the area

A= √(s(s-a)(s-b)(s-c))

s is obtained by adding the lengths of the three sides of the triangle and then dividing by 2, a, b and c are the ides of the triangle.

S=(5+6+7)/2

A=√(9(9-6)(9-5)(9-7))

=√(9×3×4×2)

=√216

=14.69km²

Assume p value for an independent samples t-test is 0.043 and the chosen level of significance is 0.05. The correct decision in

STatiana [176]

Answer: False

Step-by-step explanation:

We know that , If p-value < $\alpha$ , we reject the null hypothesis .

If p-value ≥ $\alpha$ , we are fail to reject the null hypothesis .

As per given , we have

The p value for an independent samples t-test is 0.043.

The level of significance is $\alpha=0.05$

Since , 0.043 < 0.05.

i.e. p-value < $\alpha$

It means we reject the null hypothesis .

It means the null hypothesis is false.

Hence , the correct decision in this scenario is to favor the null hypothesis : False
