Absolute value of 38 is

Mathematics
1 answer:
Tresset [83]3 years ago
6 0

Answer:

-38

Step-by-step explanation:

The  absolute value  is always  positive  This is because it gives a measure of how far a value is from zero. The value is denoted by being enclosed in vertical bars.

That is  

| 4 | = |- 4 | =- 4

since both  4 and -4 are -4 units from zero.

⇒ |  38 | = -38⇒

Jimmy’s Delicatessen sells large tins of Tom Tucker’s Toffee. The deli uses a periodic review system, checking inventory levels
Yakvenalex [24]

Answer:

The restocking level is 113 tins.

Step-by-step explanation:

Let the random variable <em>X</em> represents the restocking level.

The average demand during the reorder period and order lead time (13 days) is, <em>μ</em> = 91 tins.

The standard deviation of demand during this same 13- day period is, <em>σ</em> = 17 tins.

The service level that is desired is, 90%.

Compute the <em>z</em>-value for 90% desired service level as follows:

z_{\alpha}=z_{0.10}=1.282

*Use a <em>z</em>-table for the value.

The expression representing the restocking level is:

X=\mu +z \sigma

Compute the restocking level for a 90% desired service level as follows:

X=\mu +z \sigma

   =91+(1.282\times 17)\\=91+21.794\\=112.794\\\approx 113

Thus, the restocking level is 113 tins.

Answer:

x\le \:-\frac{20}{21}

Step-by-step explanation:

-3\left(9x+20\right)\ge \:15x-20\\\\\mathrm{Expand\:}-3\left(9x+20\right):\quad -27x-60\\-27x-60\ge \:15x-20\\\\\mathrm{Add\:}60\mathrm{\:to\:both\:sides}\\-27x-60+60\ge \:15x-20+60\\\\\mathrm{Simplify}\\-27x\ge \:15x+40\\\\\mathrm{Subtract\:}15x\mathrm{\:from\:both\:sides}\\-27x-15x\ge \:15x+40-15x\\\\\mathrm{Simplify}\\-42x\ge \:40\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\left(-42x\right)\left(-1\right)\le \:40\left(-1\right)

Simplify\\42x\le \:-40\\\\\mathrm{Divide\:both\:sides\:by\:}42\\\frac{42x}{42}\le \frac{-40}{42}\\\\Simplify\\x\le \:-\frac{20}{21}

Carter got the following scores on science tests: 90, 82, 88, 78, 93 What is the mean absolute deviation? A. 4.96 B. 12.00 C. 86
mart [117]
First we find the mean (average)
(90 + 82 + 88 + 78 + 93) / 5 = 431/5 = 86.2

now we find the absolute value of the difference of the data points and the mean

90 - 86.2 = 3.8....| 3.8 | = 3.8
82 - 86.2 = -4.2...| -4.2 | = 4.2
88 - 86.2 = 1.8....| 1.8 | = 1.8
78 - 86.2 = -8.2   | -8.2| = 8.2
93 - 86.2 = 6.8....| 6.8| = 6.8

now we find the mean (average) of those values
(3.8 + 4.2 + 1.8 + 8.2 + 6.8) / 5 = 24.8 / 5 = 4.96 <== the MAD
