Answer:

3/-8 is the slope.

Step-by-step explanation:

GREYUIT [131]3 years ago

Answer: Slope (m) = ΔY/ΔX = -3/8= -0.375

Step-by-step explanation:

θ = arctan( ΔY/ΔX) + 360°= 339.44395478042°

ΔX = 8 – 0 = 8

ΔY = 2 – 5 = -3

Distance (d) = √ΔX2 + ΔY2 = √73 = 8.5440037453175

Equation of the line:

y = -0.375x + 5 or y = -3/8x +5

When x=0, y = 5

When y=0, x = 13.333333333333

Which shows the numbers in order from least to greatest?
gavmur [86]
So just convert to a common form
I will convert to decimal since 2 of them are already decimals

to conver 1 and 3/7 to decimal, just divide 3 by 7 using a calculator
1 3/7=1.43...

so 1.38, 1.43, 1.40
the greates is .43 then .40 then .38 so the order is
least to greatest
1.38, 1.4, 1 3/7 or D

Are 27/4 and 32/3 equivalent fractions?
Blababa [14]

Answer:

no

Step-by-step explanation:

27/4 = 54/8 = 81/12 = 108/16

= 135/20 = 162/24 = 189/28 = 216/32

= 243/36 = 270/40 = 297/44 = 324/48

= 351/52 = 378/56 = 405/60 = 432/64

= 459/68 = 486/72 = 513/76 = 540/80

= 567/84 = 594/88 = 621/92 = 648/96

= 675/100 = 702/104 = 729/108 = 756/112

= 783/116 = 810/120 = 837/124 = 864/128

= 891/132 = 918/136 = 945/140 = 972/144

= 999/148 = 1026/152 = 1053/156 = 1080/160

= 1107/164 = 1134/168 = 1161/172 = 1188/176

= 1215/180 = 1242/184 = 1269/188 = 1296/192

= 1323/196 = 1350/200 = 1377/204 = 1404/208

= 1431/212 = 1458/216 = 1485/220 = 1512/224

= 1539/228 = 1566/232 = 1593/236 = 1620/240

= 1647/244 = 1674/248 = 1701/252 = 1728/256

= 1755/260 = 1782/264 = 1809/268 = 1836/272

= 1863/276 = 1890/280 = 1917/284 = 1944/288

= 1971/292 = 1998/296 = 2025/300 = 2052/304

= 2079/308 = 2106/312 = 2133/316 = 2160/320

= 2187/324 = 2214/328 = 2241/332 = 2268/336

= 2295/340 = 2322/344 = 2349/348 = 2376/352

= 2403/356 = 2430/360 = 2457/364 = 2484/368

= 2511/372 = 2538/376 = 2565/380 = 2592/384

= 2619/388 = 2646/392 = 2673/396 = 2700/400

A simple random sample of 100 observations was taken from a large population. The sample mean and the standard deviation were de
olga2289 [7]

Answer:

Se=1.2

Step-by-step explanation:

The standard error is the standard deviation of a sample population. "It measures the accuracy with which a sample represents a population".

The central limit theorem (CLT) states "that the distribution of sample means approximates a normal distribution, as the sample size becomes larger, assuming that all samples are identical in size, and regardless of the population distribution shape"

The sample mean is defined as:

\bar X =\frac{\sum_{i=1}^n x_i}{n}

And the distribution for the sample mean is given by:

\bar X \sim N(\mu,\frac{\sigma}{\sqrt{n}})

Let X denotes the random variable that measures the particular characteristic of interest. Let, X1, X2, …, Xn be the values of the random variable for the n units of the sample.

As the sample size is large,(>30) it can be assumed that the distribution is normal. The standard error of the sample mean X bar is given by:

Se=\frac{\sigma}{\sqrt{n}}

If we replace the values given we have:

Se=\frac{12}{\sqrt{100}}=1.2

So then the distribution for the sample mean \bar X is:

\bar X \sim N(\mu=80,Se=1.2)
