£75 > £70 Therefore Sally is wrong.
Step-by-step explanation:
1. First we need to find the volume of the sand pit
60x40x100= 24,000[tex]cm^{3\\[/tex]
Volume= 24,000[tex]cm^{3\\[/tex]
2. We need to convert 8 liters to [tex]cm^{3\\[/tex] so, all the units are the same
1 liter= 1,000[tex]cm^{3\\[/tex]
8 liters= 8,000[tex]cm^{3\\[/tex]
3. We then do 24,000[tex]cm^{3\\[/tex] divide by 8,000[tex]cm^{3\\[/tex] to see how many bags, we need
24,000[tex]cm^{3\\[/tex]/ 8,000[tex]cm^{3\\[/tex] = 30
so, Sally needs 30 bags
4. We know one bag cost £2.50 to know how much 30 bags cost we do
£2.50 x 30 = £75
so, we know 30 bags cost £75
5. Sally statement was said that it would cost less than £70 which is false as it costs £75
6. Therefore the final answer is £75>£70 so Sally is wrong.

She gets a deal at;
7 shirts = $97.93
Now, she wants to buy 5 shirts for her family at that given deal. Thus;
Cost of 5 shirts in dollars = (97.93 * 5)/7 = $69.95
Now, the exchange rate of dollar to krona is given as;
1 U.S. Dollar = 8.6964 Krona
Thus; $69.95 = (69.95 * 8.6964)/1 = 608.313 Krona

1. In △NBA, BO is a median. If NO=x+3 and OA=2x-9, what is the value of x?
2.In △MTV, TPis an angle bisector. If m∠MTP=12 and m∠MTV=3x-3, find the value of x.
Answers
Answer:
Step-by-step explanation:
1 . In the given triangle ΔNBA BO is a median.
By applying the property of median it divides the opposite side into two equal parts.
Therefore,
NO = OA ...(a)
We have,
NO = x+3 and OA = 2x-9
from (a)
NO = OA
x+3 = 2x-9
∴ 3+9 = 2x-x
∴ x = 12
∴ The Value of x is 12.
Que 2 - In ΔMTV
Given - TP is an angle bisector
m∠MTP = 12 , m∠MTV = 3x - 3.
Ans - TP is an angle bisector which means it divides the angle into two equal parts. (By angle bisector theorem)
∴ m∠MTP = m∠VTP ..... (a)
m∠MTV = m∠MTP + m∠VTP
∴m∠MTV = 2(m∠MTP)
∴3x-3 = 2(12)
∴3x-3 = 24
∴3x = 24 + 3
∴3x = 27
∴ x = 27/3
∴ x = 9
∴ The Value of x is 9.

Step-by-step explanation:
a) you combine like terms: 7x+9=7x-8
then subtract 7x from both sides, since 9 isn't equal to -8 there is no solution that would make it a contradiction
b) Combine likes: 13x-7=12x+21

1-5 Pairs of Angles W.S
Answers
The value of x is 26° and y is 9°.
What is linear pair angles ?A pair of neighboring angles created by the intersection of two lines is known as a linear pair of angles. When two angles share a vertex and an arm but do not overlap, they are said to be adjacent angles. Due to their formation on a straight line, the linear pair of angles are always complementary. So, the total of two angles in a pair of lines is always 180 degrees.
The value of x and y are : x= 26° and y= 9°.
As a linear pair, (5x - 17)° + (3x - 11)° = 180°.
or, 8x - 28°= 180°
8x = 180° + 28°
Therefore, the value of x is 26°.
Now,
3x - 11°= 3×26°-11° = 67°
Again,
67°+90°+(2y+5)° = 180° { being linear pair}.
157°+2y+5° = 180°
or, 2y + 162° = 180°
or, 2y = 180° - 162°
y =
Therefore, the value of y is 9°.
The value of x is 26° and y is 9°.

Suppose that kellogg believes that the average weight for a box of frosted flakes is 18 ounces. As part of a quality control effort, they sample 30 boxes and find that the mean of those 30 boxes is 18. 2 ounces. Historical records show that the standard deviation of the filling process is 0. 32 ounces. How likely is it for the sample mean to have been 18. 2 ounces or larger if the actual mean is 18 ounces and the standard deviation of the filling process is 0. 32 ounces?.
Answers
There is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.
What exactly is mean?In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. For instance, the mean for the set of data 8, 9, 5, 6, 7 is 7, since 8 + 9 + 5 + 6 + 7 = 35, and 35/5 = 7.So, let Y be a random variable with box weights.
μ = 18 ouncesSD = 0.32 ouncesThese are the sample size and mean:
Sample size (n) = 30Sample mean (y) = 18.2N's standard deviation is then roughly followed by Y ( μ = 18, SD = 0.32).
Z score is displayed as:
[tex]z=\frac{\sqrt{n}(y-u)}{S D}[/tex]Where z has a mean of 0 and a standard deviation of 1 and is a normal standard variable.
Given that the standard deviation is given and that sample size n is 30. y roughly follows the Normal distribution.
If the sample mean was 18.2 ounces or more and the actual mean was 18 ounces, the probability that this was the case is given as:
[tex]\begin{aligned}&P[Y \geq 18.2]=P\left[\frac{\sqrt{n(y-u)}}{S D} \geq \frac{\sqrt{30}(18.2-18)}{0.32}\right. \\&=P\left[z \geq \frac{\sqrt{30}+0.2}{0.32}\right] \\&=P\left[z \geq \frac{1.0954}{0.32}\right] \\&=P[z \geq 3.4233] \\&=0.0003\end{aligned}[/tex]
Therefore, there is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.

Answers
The value of m + n from getting the values of m and n from the constant polynomial P(x) = (2m - 4)x² + (5 - n)x + 13 is; 7
What is a constant polynomial?
A constant Polynomial is defined as a polynomial is a function of the form f(x) = a
where a is a real number, whose highest degree is zero.
Thus, examples of constant Polynomials are f(x) = 5, g(x) = -11 , h(y) = 7/4
Now, we are given the polynomial expression;
P(x) = (2m - 4)x² + (5 - n)x + 13
From the definition of constant Polynomials, we can say that;
2m - 4 = 0 and 5 - n = 0
Thus;
m = 2 and n = 5
Then, m + n = 2 + 5 = 7

For given triangle, the value of x is 22.
In this question, we have been given three angles of triangle.
We need to find the value of x.
We can observe that (6x - 7)° is an exterior angle.
So, the third angle of the triangle is 180° - (6x - 7)°
We know that the sum of the all angles of the triangle is 180°
2x° + (103 - x)° + [180° - (6x - 7)°] = 180°
2x + 103 - x + 180 - 6x + 7 = 180
2x - x - 6x + 103 + 180 + 7 = 180
-5x + 290 = 180
-5x = 180 - 290
-5x = -110
x = 22
Therefore, for given triangle, the value of x is 22.
