Solve for X. 3/4x+7/8=4 1/4 Enter your answer as a mixed number in simplest form in the box.
neonofarm [45]

Step-by-step explanation:

\frac{3}{4} x +  \frac{7}{8}  = 4 \frac{1}{4}

\frac{3}{4} x =  \frac{17}{4}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{34}{8}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{27}{8}

3x \times 8 = 27 \times 4

24x = 108

x =  \frac{108}{24}

x =  \frac{9}{2}

At a particular garage, 60% of the customers require an oil change, 20% require tire rotation, and 75% of customers require at l
ZanzabumX [31]

Answer:

a. 5%

b. 55%

c. 70%

Step-by-step explanation:

a. The probability of customer wanting both services (P(O&T)) is:

P(O)+P(T)+P(O\&T) = 0.75\\P(O)+P(O\&T) =0.60\\P(T)+P(O\&T) = 0.20\\P(O)+P(T)+P(O\&T) -[P(O)+P(T)+2P(O\&T)]=0.75 -(0.60-0.20)\\P(O\&T)=0.05=5\%

The probability is 5%

b. The probability that the customer will need an oil change, but not a tire rotation (P(O)) is :

P(O)+P(O\&T) = 0.60\\P(O\&T) = 0.05\\P(O) =0.60-0.05 = 0.55 = 55\%

The probability is 55%

c. The probability that the customer will want exactly one of these two services (P(O)+P(T)) is:

P(O)+P(T)+P(O\&T) = 0.75\\P(O\&T) = 0.05\\P(O)+P(T) =0.75-0.05 = 0.70 = 70\%

The probability is 70%

Suppose you have developed a scale that indicates the brightness of sunlight. Each category in the table is 4 times brighter tha
raketka [301]

According to the developed scale, a radiant day is <u>16 times</u> brighter than a dim day.

We assume the brightness of a dim day to be x.

According to the developed scale, the brightness of an illuminated day will be 4 times that of a dim day.

Thus, the brightness of an illuminated day = 4*the brightness of a dim day = 4x.

According to the developed scale, the brightness of a radiant day will be 4 times that of an illuminated day.

Thus, the brightness of a radiant day = 4*the brightness of an illuminated day = 4*4x = 16x.

Now, the ratio of the brightness of a radiant day to the brightness of a dim day = 16x:x = 16x/x = 16:1.

Thus, according to the developed scale, a radiant day is <u>16 times</u> brighter than a dim day.

The question provided is incomplete. The complete question is:

"Suppose you have developed a scale that indicates the brightness of sunlight. Each category in the table is 4 times brighter than the next lower category. For example, a day that is dazzling is 4 times brighter than a day that is radiant. How many times brighter is a radiant day than a dim day?

Dim=2

Illuminated=3

Radiant=4

Dazzling=5"
