The score that is one and a half standard deviation is 182.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x\ is\ raw\ score, \mu\ is\ mean, \sigma\ is\ standard \ deviation[/tex]
Given that:
μ = 140, σ = 28. For a z score of 1.5(one and a half):
[tex]1.5=\frac{x-140}{28} \\\\x-140=42\\\\x = 182[/tex]
The score that is one and a half standard deviation is 182.

Step-by-step explanation:
-4x + 8 = 24
Subtract 8 from both sides to isolate the x.

Melanie is making a piece of jewelry that is in the shape of a right triangle. The two shorter sides of the piece of jewelry are 5 mm and 12 mm. Find the perimeter of the piece of jewelry.
Answers
Answer:
30 mm.
Step-by-step explanation:
The longest side = sqrt(5^2 + 12^2)
= sqrt169
= 13. (Using Pythagoras).
So the perimeter = 5+12+13
= 30 mm.
Perimeter of the piece of jewelry = 30mm
What is Pythagoras theorem?Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides".
Given,
Shape of jewelry is right angle triangle ABC
length of shorter sides,
AB = 5mm
BC = 12mm
By Pythagoras theorem,
AC² = AB²+BC²
AC = √(5² + 12²)
AC = √169
AC = 13 mm
Perimeter of Triangle = AB + BC + AC
= 5 + 12 + 13
Perimeter of Triangle = 30
Hence, 30 mm is the perimeter of jewelry.

Step-by-step explanation:
Use the formula given, and input 30 for F
[tex]C = 5/9(F - 32)\\\\C = 5/9(30 - 32)\\\\C = 5/9(-2)\\\\C = -10/9 = -1 \frac{1}9 = -1.11[/tex]
30°F ≈ -1.11°C
-Chetan K
This value is approximate.
==================================================
Explanation:
You're given a temperature of 30 degrees F and your teacher wants to know the Celsius version of this temperature. Plug in F = 30 and simplify.
[tex]C = \frac{5}{9}(F-32)\\\\C = \frac{5}{9}(30-32)\\\\C = \frac{5}{9}(-2)\\\\C \approx 0.5555*(-2)\\\\C \approx -1.111\\\\[/tex]
The temperature 30 degrees F converts to approximately -1.111 degrees C. Fahrenheit temperatures below 32 degrees are below 0 when converted over to Celsius.

Breakfast eaten and the slim camp-outfit lashed to the sled, the men turned their backs on the cheery fire and launched out into the darkness. At once began to rise the cries that were fiercely sad—cries that called through the darkness and cold to one another and answered back. Conversation ceased. Daylight came at nine o'clock. At midday the sky to the south warmed to rose-colour, and marked where the bulge of the earth intervened between the meridian sun and the northern world. But the rose-colour swiftly faded. The grey light of day that remained lasted until three o'clock, when it, too, faded, and the pall of the Arctic night descended upon the lone and silent land.
As darkness came on, the hunting-cries to right and left and rear drew closer—so close that more than once they sent surges of fear through the toiling dogs, throwing them into short-lived panics.
At the conclusion of one such panic, when he and Henry had got the dogs back in the traces, Bill said:
"I wisht they'd strike game somewheres, an' go away an' leave us alone."
"They do get on the nerves horrible," Henry sympathized.
They spoke no more until camp was made.
