Answer:

D. Only one cleaning product was asked about in the survey.

Any given company can use more than one cleaning product or even use a combination of different cleaning products. The question was not specific enough, since it should have probably asked which cleaning products are used and which ones are used more frequently.

Step-by-step explanation:

the other options are wrong because:

  • A. Only 50 cleaning services were surveyed. ⇒ This actually would increase the validity of the claim because it satisfies the the condition for a valid confidence interval [np and n(1 - p) are larger than 10]-
  • B. Cleaning services were selected at random. ⇒ This actually would increase the validity of the claim.
  • C. A well-known company conducted the survey. ⇒ This actually would increase the validity of the claim.

Mark is solving the equation 4x2 + 2x = -9 using the quadratic formula.
Masteriza [31]
4x^2 + 2x = -9
4x^2 + 2x + 9 = 0

remember that the form of quadratic is ax^2 + bx + c = 0

so
a = 4
b = 2
c = 9
