Hey!Here is ur answer:
Danielle is wrong cause 'she has included a decimal'.
U might doubt that zero is might not be an integer but it is a neutral integer.
HOPE IT MAKES UR DAY BETTER!!
Danielle says that her set of numbers are integers the statement is wrong as the set contain decimal number because decimal numbers are not integers, so option C is correct.
What are integers?All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a collection of integers results.
Given:
Danielle says that her set of numbers are integers. Left-brace negative 253, negative 45, negative 0.9, 0, 26 Right-brace,
Write the above phrase in the mathematical form as shown below,
(-253, -45, -0.9, 0, 26)
As we know that integers are whole numbers, they can't be a decimal numbers or a fraction,
Thus, the set of numbers are integers is wrong because it contains decimal numbers.

Toby goes on holiday to Geneva, Switzerland. In Geneva, Toby sees a watch costing 193.75 CHF (Swiss Francs). In Manchester, an identical watch costs £145. Given that £1=1.55CHF a) In which city is the watch cheaper. b) By how much is it cheaper (in £) i need help on part b , pleeeeaseeee help;(
Answer:
The watch is cheaper in Geneva, Switzerland by a value of £20
Step-by-step explanation:
To get the city in which the watch is cheaper, what we need to do is to express the price of the watch in the same currency.
Since pounds is also used in the b part of the question, it would be easier working with it.
In Geneva, the price of the watch is 193.75 CHF
from our conversion formula;
£1 = 1.55 CHF
£x = 193.75 CHF
We cross multiply to get the value of x
(193.75 * 1)/1.55
= 193.75/1.55 = £125
We can see that the watch costs less in Geneva and higher in Manchester
By how much is it cheaper?
We can calculate this by subtracting the value in Geneva from the value in Manchester
That would be 145-125 = £20 cheaper

And, The line of best fit has the equation;
⇒ y = 2.5x - 1.5.
Now, At x = 3;
⇒ y = 2.5x - 1.5.
⇒ y = 2.5 × 3 - 1.5.
⇒ y = 7.5 - 1.5
⇒ y = 6.0
Thus, The value of y at x = 3 is,

Let's start with sectioning off the little squares on the left that are jutting out of the top and bottom. Both of the squares are C*E, so multiply C*E twice to get the area of those little squares. That comes out to 12 feet.
Next is the main quadrilateral, the big one. You have to cut it off at the point the triangle starts to slope, so the end fo B.
But you also have to get the left part, so you have to add the length of C to the length of B to get the length of the quadrilateral. A encompasses the entire height, but not the part we want, because we already isolated those little squares. To get the height, just subtract the two E parts. The height is 6. The length is 8 feet. Multiply and get 48.
Add that to the previous 12 feet calculated to get 60.
Next, the triangle. The height is A, but only with one E. So subract the other E to get a height of 9. The length is D, but you have to subract B because that is part of the earlier quadrilateral. That makes it 9.
The formula for a triangle is height * length / 2. So, plug in the numbers-- 9 * 9 / 2
81/2
40.5.
Add to the previous 60 we got and that makes 100.5 square feet.

A candy company claims that 25% of the candies in its bags are colored green. Steve buys 32 bags of 32 candies, randomly selects one candy from each, and counts the number of green candies. If there are 7, 8, or 9 green candies, Steve will conclude that the company's claim is correct. What is the probability of Steve agreeing with the company's claim? Use Excel to find the probability.
Answer:
45.88%
Step-by-step explanation:
We have in this case a binomial distribution when p = 0.25, since the probability is 25%
. The formula that we will use in excel is BINOM.DIST, separated by commas we must put the value of x, n, p and also if it is true or false. We know that n equals 32.
In this case we need to know when x = 7, 8 and 9 and add this, and thus we will obtain the probability:
P (X = 7) + P (X = 8) + P (X = 9)
Excel formulas: = BINOM.DIST (7,32,0.25, FALSE) + BINOM.DIST (8,32,0.25, FALSE) + BINOM.DIST (9,32,0.25, FALSE)
P = 0.1546 + 0.1610 + 0.1431
P = 0.4588
Probability that steve agrees with the company's claim 45.88%

Find the volume of a cone with a height of 9 cm and a base of 5 cm
Answer:
V=πr2h
3
Step-by-step explanation:
Answer:
15 cm³
Step-by-step explanation:
The formula for the volume of a cone is:
V = πr²h /3
where r is the radius and h is the height
Let's substitute the given values into this equation:
V = πr²h /3
(Remember that the base of a cone is a circle and the formula for the area of a circle is πr²)
V = πr²h /3
V = (5)(9/3)
Solve:
V = (5)(9/3)
V = (5)(3)
V = 15
Therefore, the volume of the cone is 15 cubic centimeters.
Howard needs new gutters for the front and both sides of his home. The front of the house is 50 ft 8 in., and each side is 22 ft 9 in. Wide. What length of gutter must he buy?
Answer:
95 ft 10 in
Step-by-step explanation:
We need to add the lengths of the front of the house and both sides of the house:
50 ft 8 in + 2(22ft + 9in)
= 50ft + 8 in + 44ft + 18in
= 94ft + 22in
12 inches = 1 foot
22 inches = 1 ft 10 in
Therefore, the length of the gutter he must buy must be:
94 ft + 1 ft + 10 in
= 95 ft 10 in

Janice is traveling at a constant rate. She traveled 243 miles on 9 gallons of gas and 324 miles on 12 gallons of gas. How many miles can Janice travel on one gallon of gas?
Divide total miles driven by number of gallons of gas used.
243 miles / 9 gallons = 27 miles per gallon
324 miles / 12 gallons = 27 miles per gallon.
She can drive 27 miles on one gallon of gas.

The surface area of a cone is given by the formula S = pi*t + pi * r ^ 2 the formula for LSlant height ( l = S - r ^ 2 l = S + r ^ 2 0 l = s/pi - r ^ 2 0 l = 5/pi + r ^ 2
Answer:
[tex]l = \frac{S}{\pi r} - r[/tex]
Step-by-step explanation:
Given the surface area of a cone expressed as S = [tex]\pi r^{2} +\pi rl[/tex] where r is the radius of the cone and 'l' is its slant height. To find the slant height from the formula, we will make l the subject of the formula as shown;
[tex]S = \pi r^{2} + \pi rl\\S = \pi r (r + l)\\\frac{S}{\pi r} = r+l\\l = \frac{S}{\pi r} - r\\[/tex]
The final expression gives the value of the slant height.
Answer: l=s/3.14-r2
