Answer:
93/481Step-by-step explanation:
Total number of integers from 300 through 780, inclusive:
780 - 299 = 481Number of integers with at least one of digit 1:
Hundreds - 0,Tens - 5*10 = 50 (31th, 41th, 51th, 61th, 71th)Units - 4*9 + 7 = 43 (300 till 699 and 700 till 780)So in total 50 + 43 = 93The probability is:
P = favorable outcomes/total outcomes = 93/481due in 10 minutes help with explanation
Answer:
first box: -9
second box: -20
Step-by-step explanation:
Group the terms with c and the ones without c:
9c - 15c - 3c = -9c
-12 - 8 = -20
So the simplification is -9c + -20
(which is the same as -9c - 20)
Order from least to greatest.

Dave bakes 12 cakes in 3 minutes. If b represents the numbers cakes David bakes in minutes . What is a linear equation that represents this situation
Answer:
The linear equation will be:
b = 4a
Here,
b = numbers of cakes David bakes
a = the time taken by David to bake cakes
Step-by-step explanation:
Let 'b' represents the numbers of cakes David bakes in minutes.
Let 'a' represents the time David takes to make 12 cakes
As Dave bakes 12 cakes in 3 minutes.
unit rate = 12/3 = 4 cakes / per minute
The unit rate can also be treated as a slope as it is just representing the rate of change.Thus, the linear equation will be:
b = 4a
Here,
b = numbers of cakes David bakes
a = the time taken by David to bake cakes
VERIFICATION
if a = 3 minuts
then
b = 4(3) = 12 cakes
and
if a = 2 minutes
then
b = 4(2) = 8 cakes
and
if a = 1 minute
then
b = 4(1) = 4 cakes
Thus, the required equation is:
b = 4a
Here,
b = numbers of cakes David bakes
a = the time taken by David to bake cakes
what is 1 and 5/32 as a decimal
Answer:
1 5/32 is equal to 1.15625 in decimal form.
Step-by-step explanation:
Hope this helped, Have a Great Day!!
1 and 5/32 is equivalent to 1.15625 as a decimal.
To convert the mixed number 1 and 5/32 to a decimal, you need to combine the whole number and the fractional part.
First, you convert the fractional part to a decimal.
The denominator of 32 tells you that there are 32 equal parts in a whole.
To determine the value of 5/32, you divide the numerator (5) by the denominator (32):
5 ÷ 32 = 0.15625
Next, you add the decimal value of the fractional part (0.15625) to the whole number (1):
1 + 0.15625 = 1.15625
Therefore, 1 and 5/32 is equivalent to 1.15625 as a decimal.

(((95*26)-470)-470)/16)-35
Answer:
Its either 60.625 or 90
Step-by-step explanation:
((2470 - 470)/16) - 35
(2000/16) - 35
125 - 35

90 is true if you made a mistake in adding two 470's, but if this is the actual equation, it is 60.625
(or when you follow the order of the numbers it becomes the 61 number)

Find the slope-intercept form between the two points (0,-4) and (-3,-10) * 2 points
Your answer
Answer:
Y=2x-4
Step-by-step explanation:
Read this E[2X^2 â€" Y].
I know part of it is read as the expected value of two times x square but what do these symbol mean â€" Y.
Write it down in English letters not mathematical expression
Thanx
Looks like a badly encoded/decoded symbol. It's supposed to be a minus sign, so you're asked to find the expectation of 2X ² - Y.
If you don't know how X or Y are distributed, but you know E[X ²] and E[Y], then it's as simple as distributing the expectation over the sum:
E[2X ² - Y] = 2 E[X ²] - E[Y]
Or, if you're given the expectation and variance of X, you have
Var[X] = E[X ²] - E[X]²
→ E[2X ² - Y] = 2 (Var[X] + E[X]²) - E[Y]
Otherwise, you may be given the density function, or joint density, in which case you can determine the expectations by computing an integral or sum.

Step-by-step explanation:
Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.
To find perimeter, we need to add up all the sides.
Because it's a square each side has the same length.
There are 4 sides.
5 x 4 = 20
or 5 + 5 + 5 + 5 = 20
The perimeter is 20 feet

Triangle X Y Z has centroid S. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments X W, Y V, and Z T. The length of line segment T S is 3 m minus 1, the length of line segment S Z is 4 m + 8, and the length of line segment X S is 2 m + 12.
S is the centroid of triangle XYZ.
What is the length of SW?
Answer:
it is indeed B
Step-by-step explanation:
a few years late but its fine right
The length of SW will be 9.5. Each median will be divided into segments by the centroid at a ratio of 2:1.
What is the triangle?A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
The ratio of the centroid divides each median into segments will be 2:1.
[tex]\rm \frac{SZ}{TS} = \frac{2}{1} \\\\ \frac{4m+8}{3m-1} = \frac{2}{1}\\\\ 4m+8 = 2 (3m-1) \\\\ 4m+8 = 6m -2 \\\\ 2 m = 10 \\\\ m = 5[/tex]
The ratio of the centroid divides each median into segments will be 2:1.
[tex]\rm \frac{XS}{SW} = \frac{2}{1}\\\\ \rm \frac{2 m +12}{SW} = \frac{2}{1}\\\\ SW = \frac{19}{2}\\\\ SW = 9.5[/tex]
Hence the length of SW will be 9.5.
