3.25 pounds

Step-by-step explanation:

x + 4 (1/2) + 3 (1/2) = 11

x + 4.25 + 3.5 = 11

x + 7.75 = 11

x = 11 - 7.75

From the answer choices available the answer that is correct is that for day-to-day business data analysis, most firms rely on a large staff of expert statisticians. This is because on a daily basis firms receive large sets of data from all of their business movements, therefore a large staff of highly experienced individuals is needed in order to handle and document all of these numbers carefully so that no mistakes are made.

Shannon test-drives a car in Germany and drives 95 kilometer per hour. What is her speed in miles per hour? (1 kilometer < 0.

victus00 [196]

Answer:

58.9 miles per hour

Step-by-step explanation:

Step 1: Convert 95 Kilometers per hour to miles per hour

1 Kilometer = 0.62 miles

95 Km x $\frac{0.62 miles}{1 km}$

cancel Km

95 Km x $\frac{0.62 miles}{1 km}$ = $\frac{95}{1}$ x $\frac{0.62 miles}{1}$ = $\frac{58.9 miles}{1}$ or 58.9 miles

Change it into speed

58.9 miles per hour (59 miles per hour (Round off))

(Note: I don't know if I should round off because the instructions aren't that clear. This solution might or might not have been thought to you by your lecturer.)

For what values of a does the equation

mihalych1998 [28]

Answer:

The value of a which equation have 2 , - $\frac{7}{4}$

Step-by-step explanation:

Given expression as :

2 a - 4 x = 4 - a² × x

The equation lies in the interval ( - 8 , - 2 )

∵ equation lies in the interval , so it must satisfy the equation

So , 2 a - 4 × ( - 8 ) = 4 - a² × ( - 8 )

Or, 2 a + 32 = 4 + 8 a²

Or, a + 16 = 2 + 4 a²

So, equation can be written as :

4 a² - a - 14 = 0

Or, 4 a² - 8 a + 7 a - 14 = 0

Or, 4 a ( a - 2 ) + 7 ( a - 2 ) = 0

Or, ( a - 2 ) ( 4 a + 7 ) = 0

∴ a = 2 And - $\frac{7}{4}$

Hence The value of a which equation have 2 , - $\frac{7}{4}$ Answer
