Answer: 7

Step-by-step explanation:

Given : The recommended daily allowance for vitamin c is 60 mg per day .

Then, for one whole week , the recommended allowance for vitamin c will be :-

7\times60=420\text{ mg}

Also, there are 70 mg of vitamin C per 100 g orange.

1 g = 1000 ml

The proportion of Vitamin C in 100 g = \dfrac{70}{100000}=0.0007

1 oz =28.3495 grams

Then, 3\ oz= 3\times28.3495=85.0485 \text{ gm}=85048.5\ mg

Then, amount of vitamin C in 85048.5 mg = 0.0007\times85048.5=59.53395\approx59.53\ mg

Then, the number of oranges have to eat each week to meet this requirement= \dfrac{420}{59.53}\approx7

Hence,  about 7 oranges you would have to eat each week to meet this requirement.

olchik [2.2K]

Answer:

The probability that exactly one switch is good is

P(x) =0.0392

Step-by-step explanation:

The probability that a switch is defective is:

P(D) = \frac{2}{100} =0.02

The probability that a switch is not defective is

P(D') = 1-P(D)=0.98

Therefore, if two switches are selected, the probability that exactly 1 is good is:

P(1=1)=P (D) P (D ') + P (D') P (D)

P(x)=(0.02)(0.98) + (0.98)(0.02)

P(x) =0.0392

Nataliya [291]
First, i put the equation in y=mx+b by dividing 2, since its 2y. since it’s perpendicular we’re talking about you switch the sides (opposite reciprocals). the rest should be self explanatory.

Liam says - (5/12) is equivalent to 5/-12. Explain if Liam is correct by completing the statements below.
makkiz [27]

A positive number divided by a positive number results in a negative quotient, and it's opposite is always positive. The fraction 5/-12 can be described as a positive number divided by a negative number, which always results in a negative quotient. The fractions have different value, so Liam is not correct.
