Scorpion4ik [409]

Answer:

The inequality representing how many hours he should work in order to reach his goal would be

$x\geq 23.14$

where $x$ represents the number of hours Sean works.

Step-by-step explanation:

Hourly earnings of Sean from after school job = $6.70

Let Sean work for $x$ hours in order to earn at least $155.

We will use unitary method to find earning for $x$ hours.

If 1 hour earnings = $6.70

∴ in $x$ hours earnings in dollars would be = $6.70\times x=6.7x$

Now, we know Sean needs at least $155 to buy a new video game.

This means his earnings working $x$ hours must be at least $155.

Thus, the inequality representing how many hours he should work in order to reach his goal would be

$6.7x\geq 155$

Dividing both sides by 6.7.

$\frac{6.7x}{6.7}\geq \frac{155}{6.7}$

$x\geq 23.14$ (Answer)

Thus, Sean should work a minimum of 23.14 hours to earn at least $155.

Suppose there is a 17.5 % probability that a randomly selected person aged 35 years or older is a smoker. Inâ€‹ addition, there

nexus9112 [7]

Answer:

The answer is 43% or 0.43

Step-by-step explanation:

Given:

Probability that person selected aged 35years or older is a smoker = 17.5%

Probability that person selected aged 35years or older is a female comma =25.5%

Solution:

a) Probability (35yrs or older is a smoker) + probability (35years or older is a female comma)

= 17.5% + 25.5%

= 43% 0r 0.43

b) No, it would not be unusual because it is by chance, it may and it may not.

which function has real zeros at x = −10 and x = −6? f(x) = x2 16x 60 f(x) = x2 − 16x 60 f(x) = x2 4x 60 f(x) = x2 − 4x 60

LiRa [457]

Answer:

Option A is correct

The function $x^2+16x+60$ has real zeroes at x =-10 and x =-6

Explanation:

Given: The real zeroes or roots are x = -10, and x = -6

To find the quadratic function of degree 2.

$x^2- (\alpha+\beta)x + \alpha\beta =0$ where α,β are real roots. ....[1]

Here, α= -10 and β= -6

Sum of the roots:

α+β = -10+(-6) = -10-6 = -16

Product of the roots:

αβ = (-10)(-6)= 60

Substitute these value in equation [1] we have;

$x^2-(-16)x+60 = x^2+16x+60$

Therefore, the quadratic function for the real roots at x =-10 and x =-6 ;

$x^2+16x+60$
