We can simplify by reducing factors between the 5 and the 50, as well as between the 42 and the 3.
Answer:Part a) 
Part b) When Jenny divides the square root of her favorite positive integer by 
, the result is an integer.
Step-by-step explanation:
Let
x-------> the favorite positive integer
Part a)
1) For 
-----> the product results in an integer
thus
The number could potentially be Jenny's favorite positive integer
2) For 
-----> the product results in an integer
thus
The number could potentially be Jenny's favorite positive integer
3) For 
-----> the product results in an integer
thus
The number could potentially be Jenny's favorite positive integer
Part B)
1) For
-----> the outcome is an integer
2) For
-----> the outcome is an integer
3) For
-----> the outcome is an integer
Therefore
When Jenny divides the square root of her favorite positive integer by , she obtains an integer as a result.
Answer: OPTION C.
Step-by-step explanation:
It is essential to consider the following:
Dilation:
- A transformation where the image retains the same shape as the original but differs in size.
- Dilation maintains the order of points.
- Measurements of angles remain unchanged.
Translation:
- A transformation that keeps the image identical in size and shape to the original.
- Translation preserves the ordering of points.
- The angle measurements do not change.
Consequently, since Square T underwent translation followed by dilation to form Square T'', we conclude that the rationale explaining why they are similar is:
Translations and dilations maintain the order of points; thereby, the corresponding sides of squares T and T″ are proportional.
Answer:
£170,000
Step-by-step explanation:
En 2010, Rafik adquirió una casa. Supongamos que el precio de compra fue $x. En 2015, Rafik vendió la casa a Bianca obteniendo un 20% de ganancia. Esto se traduce en 20% de x lo que equivale a 0.2 × x = 0.2x. Por tanto, Rafik vendió la casa a Bianca por x + 0.2x = 1.2x. Bianca compró la casa a 1.2x.
La casa fue vendida por Bianca en 2019 con una pérdida del 5%. Esto implica que el 5% de pérdida equivale a 0.05(1.2x) = 0.06x.
Por consiguiente, la venta de la casa por Bianca se realizó a 1.2x - 0.06x = 1.14x. Dado que la casa se vendió por £193,800.
⇒ 1.14x = 193,800
x = 193,800/1.14
x = £170,000
Rafik pagó £170,000 por la casa en 2010.
Let the events be defined as follows:
A=Nathan suffers from an allergy
~A=Nathan does not suffer from an allergy
T=Nathan receives a positive test result
~T=Nathan does not receive a positive test result
According to the provided data,
P(A)=0.75 [ probability indicating that Nathan is allergic ]
P(T|A)=0.98 [ probability of obtaining a positive test result if Nathan is allergic to Penicillin]
We aim to calculate the probability that Nathan is both allergic and tests positive
P(T n A)
Using the definition of conditional probability,
P(T|A)=P(T n A)/P(A)
By substituting the known values,
0.98 = P(T n A) / 0.75
We then solve for P(T n A)
P(T n A) = 0.75*0.98 = 0.735
Hope this assists you!!
