A block of concrete is 1m long, 50cm wild and 4cm thick. 1.calculate the volume of the block in cm3 .2.if 1cm has a mass of 2.7g, find the mass of the block in kg
9514 1404 393
Answer:
20,000 cm³54 kgStep-by-step explanation:
1 m is 100 cm, so the volume is ...
V = LWH
V = (100 cm)(50 cm)(4 cm) = 20,000 cm³ . . . volume
__
The mass is ...
(20,000 cm³)(2.7 g/cm³) = 54,000 g = 54 kg
The mass of the block is 54 kg.
You roll two six-sided number cubes. Let X be the number of odd numbers that show up on the two cubes. What are the
possible values of X?
0.1.2
0,1,2,3,4,5,6
1,3,5
0,1,3,5
Answer:
The possible values of X are 0,1 or 2.
Step-by-step explanation:
In this question:
Two number cubes are going to be rolled.
X is the number of odd numbers that show up on the two cubes.
For each cube, there is one number, which can be even, or odd.
Thus, there can be no odd numbers, one odd number or two odd numbers, and the possible values of X are 0,1 or 2.

Leave no cells blank. Enter 0 as an answer if undefined.)
Answer:
Kindly check explanation
Step-by-step explanation:
Given :
A.)
Vehicle speeds on highway (9 vehicles) 74, 82, 67, 73, 65, 41, 74, 49, 85
Ordered data :
41, 49, 65, 67, 73, 74, 74, 82, 85
Sample size, n = 9
Median = 1/2 * (n +1) th term
Median = 1/2 * 10 = 5th term
Median value = 73
Midrange = (Maximum + minimum) / 2
Midrange = (85 + 41) / 2 = 126 / 2 = 63
Geometric mean : √(x1*x2*.. xn)^1/n
Geometric Mean:
(41*49*65*67*73*74*74*82*85)^1/n
= 66.19
B.)
Sodium grams in canned soup (8 varieties)
X = 4.22, 3.60, 2.68, 2.75, 2.70, 4.17, 2.72, 4.29
Ordered data:
2.68, 2.70, 2.72, 2.75, 3.60, 4.17, 4.22, 4.29
Sample size, n = 8
Median = 1/2 * (n +1) th term
Median = 1/2 * 9 = 4.5th term
Median value = (2.75+ 3.6) / 2 = 3.175
Midrange = (Maximum + minimum) / 2
Midrange = (4.29 + 2.68) / 2 = 3.485
Geometric mean : √(x1*x2*.. xn)^1/n
Geometric Mean:
(2.68*2.70*2.72*2.75*3.60*4.17*4.22*4.29)^1/8
= 3.32

1, 1, 1, 2, 3, 3, 3, 3, 4, 5, 6, 13
Sample size, n = 12
Median = 1/2 * (n +1) th term
Median = 1/2 * 13 = 6.5th term
Median value = 3
Midrange = (Maximum + minimum) / 2
Midrange = (1 + 13) / 2 = 7
Geometric mean : √(x1*x2*.. xn)^1/n
Geometric Mean:
(1*1*1*2* 3*3*3*3*4* 5*6*13)^1/12

Answer:
[tex]P(t) = 29816591(1.025)^{t-5}[/tex]
Step-by-step explanation:
Equation:
The equation for the population of California, in t years after 1990, is given by:
[tex]P(t) = 29816591(1.025)^t[/tex]
In which 29816591 is the initial population, that is, the population in 1990.
From 1995:
First, we have to find the population in 1995(5 years after 1990), which is P(5), which we will consider as the initial value in the equation.
So
[tex]P(5) = 29816591(1.025)^5 = 33734736[/tex]
So
Since t is still given in years after 1990, we have to subtract t by 1995 - 1990 = 5 in the exponent. So
[tex]P(t) = 29816591(1.025)^{t-5}[/tex]

Solve the system of linear equations by elimination. Show your work
2x-y=-3
4x + 3y = -21
Answer:
x = -3, y = -3
Step-by-step explanation:
Solve the following system:
{-y + 2 x = -3 | (equation 1)
3 y + 4 x = -21 | (equation 2)
Swap equation 1 with equation 2:
{4 x + 3 y = -21 | (equation 1)
2 x - y = -3 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 3 y = -21 | (equation 1)
0 x - (5 y)/2 = 15/2 | (equation 2)
Multiply equation 2 by 2/5:
{4 x + 3 y = -21 | (equation 1)
0 x - y = 3 | (equation 2)
Multiply equation 2 by -1:
{4 x + 3 y = -21 | (equation 1)
0 x+y = -3 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{4 x+0 y = -12 | (equation 1)
0 x+y = -3 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -3 | (equation 1)
0 x+y = -3 | (equation 2)
Collect results:
Answer: x = -3, y = -3

Jack rolls a fair number cube and spins the spinner. What is the probability that jack will get a number less than 4 and lands on blue?
Answer:
7.14%
Step-by-step explanation:
A fair number cube has 6 sides while a normal spinner has 7 different colors. In order to find the probability of Jack getting a number less than 4 and lands on blue, we need to find the probability of each individual event and multiply them together. Since the cube has six sides and 3 options that are less than 4 then the probability of getting less than 4 is 3/6. On the wheel there are 7 colors and only one is blue, therefore, the probability is 1/7. Now we multiply these fractions together.
[tex]\frac{3 * 1}{6 * 7} = \frac{3}{42}[/tex] or 0.0714 or 7.14%
Therefore, the probability of this event happening is 7.14%
The probability of this event is 7.14%.
What is the number of sides in a fair number cube?A fair number cube has 6 sides.
While a normal spinner has 7 different colors.
In order to find the probability of Jack getting a number less than 4 and lands on blue,
we have to find the probability of each individual event and then multiply them together.
The cube has six sides and 3 options that are less than 4 then the probability of getting less than 4 is 3/6.
On the wheel there are 7 colors and only one is blue.
Therefore, the probabilitiy is 1/7.
Now we multiply these fractions together.
[tex]\frac{3\times 1}{6\times 7} =\frac{3}{42}= 0.0714[/tex]
[tex]\frac{ 0.0714 }{100}=7.14\%[/tex]

True or False: The first number in an integer subtraction problem tells you where to start on the board.
Answer:
i think false
Step-by-step explanation:
Let f(x)=-4(2)^x. The graph of g(x)=f(x)+k is shown below. Identify the value of k.
Given:
The function is:
[tex]f(x)=-4(2)^x[/tex]
The graph of the function [tex]g(x)=f(x)+k[/tex] is given.
To find:
The value of k.
Solution:
We have,
[tex]f(x)=-4(2)^x[/tex]
[tex]g(x)=f(x)+k[/tex]
Using these two functions, we get
[tex]g(x)=-4(2)^x+k[/tex]
From the given graph it is clear that the graph of g(x) passes through the point (0,2). It means the point (0,2) satisfies the function g(x).
Substituting [tex]g(x)=2[/tex] and [tex]x=0[/tex] in the above function, we get
[tex]2=-4(2)^0+k[/tex]
[tex]2=-4(1)+k[/tex]
[tex]2=-4+k[/tex]
[tex]2+4=k[/tex]
[tex]6=k[/tex]
Therefore, the value of k is 6.

Tiana is going to swim the length of her swimming pool. The width of her pool is 42 yards and the diagonal distance from one corner to the opposite corner is 58 yards. How far will Tiana swim when she swims the length?
Answer:
40 yards
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Using this, let's set the length as x.
42² + x² = 58²
Simplify.
1764 + x² = 3364
Subtract 1764 from both sides.
x² = 1600
Take the square root.
x = 40
Thus, the length she would swim would be 40 yards.
Answer:
40

Answer:
A. For every 1 inch of mercury the pressure increases, the boiling point is expected to increase by 1.9°F
Step-by-step explanation:
A regression model is in the form :
y = mx + c
With m being the slope = rate of change
In regression, the value of the slope gives the rate of change in y value per unit increase in the value of x
The slope in the question above is 1.9, this means for every unit increase in mercury pressure, then boiling point, y increases by 1.9°F
