1.488 divided by 2.1 rounded to nearest tenth

What single transformation is required to map one of these congruent triangles onto the other?

fredd [130]

First one
why?? because i is just like a mirror it is reflected on the other side

Given:
sugar cookies = x = 1 batch = 2 3/4 cups of flour
loaves of banana bread = y = 1 loaf = 2 1/2 cups of flour

2 3/4 x + 2 1/2 y <u><</u> 36

the total number of cups of flour used per batch of sugar cookies and loaf of banana bread should not exceed 36 cups of flour.

80 hours of labor work 40 assistant 25 hr earn $22per hour 15 per hr. earn$10 how much labor

Vlada [557]

80 hr total
the assistants is not info
25 hr X $22 per = $500
15 hr X $10 = $150
$500 + $150 = $650
now for hr you have 80, you worked 25 + 15 = 40, 80 - 40 = 40
your answer is 40 --------------------------------------|^|

PLEASE HELP ASAP I always give brainliests!

first to find average age add all the ages divide by number of ages 4

5+4=9

9+6=15

15+39=54

54/4=13.5

For standard deviation find the mean/average

13.5

then subtract the mean from each number/age

5-13.5=-8.5

4-13.5=-9.5

6-13.5=-7.5

39-13.5=25.5

then square each number

-8.5^2=-72.25

-9.5^2=-90.25

-7.5^2=-56.25

25.5^2=650.25

then find the mean/average of the new numbers

-72.25+-90.25+-56.25+650.25=431.5

431.5/4=107.85

then take the square root of the new mean/average

$\sqrt{ 107.875}\\10.38628903...$

A worker at a landscape design center uses a machine to fill bags with potting soil. Assume that the quantity put in each bag fo

defon

Answer:

a) The expected value is given by:

$E(X) =\frac{a+b}{2}= \frac{10+12}{2}= 11$

The variance is given by:

$Var(X) = \frac{(b-a)^2}{12}= \frac{(12-10)^2}{12}= 0.3333$

And the standard deviation is just the square root of the variance and we got:

$Sd(x) = \sqrt{0.3333}= 0.5774$

b) $P(X$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a}, a \leq x \leq b$

And using this function we got:

$P(X$

c) $P(X>10.5)$

And using the complement rule and the cumulative distribution function we got:

$P(X>10.5)= 1-P(X$

Step-by-step explanation:

For this case we define the random variable X=quantity put in each bag , and we know that the distribution for X is given by:

$X \sim Unif (a= 10, b =12)$

Part a

The expected value is given by:

$E(X) =\frac{a+b}{2}= \frac{10+12}{2}= 11$

The variance is given by:

$Var(X) = \frac{(b-a)^2}{12}= \frac{(12-10)^2}{12}= 0.3333$

And the standard deviation is just the square root of the variance and we got:

$Sd(x) = \sqrt{0.3333}= 0.5774$

Part b

For this case we want this probability:

$P(X$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a}, a \leq x \leq b$

And using this function we got:

$P(X$

Part c

For this case we want this probability:

$P(X>10.5)$

And using the complement rule and the cumulative distribution function we got:

$P(X>10.5)= 1-P(X$
