The equation that models the relationship between the amount of money Sarah has left is 55- 0.65x= y
Answer:
(x+5) and (x-7).
Step-by-step explanation:
The given equation is :

We need to write it in factored form.
We know that,
7×5 = 35 and 7-5 = 2
So,

Hence, the required factors are (x+5) and (x-7).
Answer:
Option 4.
Step-by-step explanation:
Reciprocal of the second fraction turns the product into the division of the two fractions, which equals to 1.


Two fractions are said to be the reciprocal or multiplicative inverse of each other, if their product is 1.
Answer:
0.98046
Step-by-step explanation:
Given:
Here we are required to find
P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by
<em>z = (x - μ) / σ</em>
So 5.48 we have z = -2.714 and 5.82 we have z = 2.143
Therefore we have the area of interest on the normal distribution chart given by
:
P( -2,714 < z < 2.143)
= 1 - P(Z<-2.714) + P(Z > 2.143)
= 1 - P(Z<-2.714) + (1 - P(Z < 2.143))
= 1 - 0.00336 + 1 - 0.98382
= 1 - 0.01954 = 0.98046
