Answer:
0.2690 kg
Step-by-step explanation:
Given that:
For cutting a 4.5 kg block of cheese; the standard deviation:
[tex]S_x = 0.1 \ kg[/tex]
For a large no of blocks, at 95% confidence level;
Using the t table; where the degree of freedom is infinity or > 30
t-distribution (t) = 2
∴
[tex]P_x = tS_x[/tex]
[tex]P_x = 2 \times 0.1[/tex]
[tex]P_x = 0.2 \ kg[/tex]
The system uncertainty as a result of the accuracy [tex]B_x[/tex] is:
[tex]B_x = 1.5\% \ of \ reading[/tex]
[tex]B_x = (\dfrac{1.5}{100})(12 kg)[/tex]
[tex]B_x = 0.18 \ kg[/tex]
The total uncertainty for a single experiment with a 95% confidence interval will be:
[tex]w_s = ( B_x^2 + P_x^2)^{\frac{1}{2}[/tex]
[tex]w_s = (0.18^2 + 0.2^2)^{\frac{1}{2}[/tex]
[tex]\mathbf{w_s = 0.2690 \ kg}[/tex]

A square has the same perimeter as the rectangle.
What is the side length of this square?
Answer:
a square and rectangle have the same perimeter. the length of the rectangle is 4 cm less than twice the side of the square, and the width of the rectangle is 6 cm less than the side of the square.
Step-by-step explanation:
jayfeather friend me
The required side length of the square is 5 cm.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
Given that,
Length of rectangle = 7 cm,
Width of rectangle = 3 cm.
The perimeter of rectangle = 2(length + width)
= 2(7 + 3)
= 2 x 10
= 20
Also, given that the perimeter of the rectangle is equal to the perimeter of a square,
Let side of square is a then perimeter = 4a
⇒ 4a = 20
⇒ a = 5
The side length of the square is 5 cm.

Given that the function g is defined by the rule g(x)=3-2x,determine the following
g(a)=
Answer:
The value of g(a) is:
g(a) = 3 - 2aStep-by-step explanation:
Given
As the function g(x) is given by
[tex]g(x)=3-2x[/tex]
To determine
g(a) = ?
In order to determine g(a),
substitute x = a in the function g(x) = 3 - 2x
g(x) = 3 - 2x
g(a) = 3 - 2(a)
g(a) = 3 - 2a
Therefore, the value of g(a) is:
g(a) = 3 - 2aHank cut his pizzainto 10 pieces and ate 6 of the pieces.Rose cut her pizza into 5 pieces and ate the same amount as hankShow this on a drawing

Find the value of x so that the ratios are equivalent.
1:8 and 4:x
X =
Answer:
32
Step-by-step explanation:
1 : 8 = 4 : 32
So, 4 : x = 4 : 32
x = 32
The value of x from the given ratios is 32.
Given that, the ratios 1:8 and 4:x are equivalent.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here,
1:8 =1/8
4:x =4/x
Ratios are equivalent 1/8 = 4/x
x= 4×8
x=32
Therefore, the value of x from the given ratios is 32.

Two six-sided dice are rolled. Find the probability that the first die is not a 5, and that the second die is not a 2
Answer:
P(not 5, not 2) = 5/6 x 5/6 = 25/36
Step-by-step explanation:
Answer:
The correct answer is 5/6 bc
Step-by-step explanation:
The correct answer was 5/6
Let E be the event "the first die is a 5" and F be the event "the second die is a 2." E and F are independent events. Hence so are the complements of E and F. This means that the probability of the complement of E given the complement of F is just the probability of the complement of E, which is 1 - 1/6 = 5/6.

6sqrt20 + 8sqrt5 - 5sqrt45
Answer:
20√5 - 10√10
Step-by-step explanation:
6√20 + 8√5 - 5√45
first, 6√20 and 5√45 need to be simplified. 8√5 cannot be simplified any further:
6√20 = 6√4•5 = 6√2•2•5 = 6•2√5 = 12√5
5√45 = 5√8•5 = 5√2•2•2•5 = 5•2√2•5 = 10√10
now:
12√5 + 8√5 - 10√10
then, add the coefficients of 12√5 and 8√5
20√5 - 10√10
the left over numbers cannot be combined because they do not have a common radical, making 20√5 - 10√10 the final answer
