The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression.

a²b(7 + 10b +14b²)

Answer:

a^2b(7 + 10b + 14b^2)

Step-by-step explanation:

Given : 7a^2b + 10a^2b^2 + 14a^2b^3

To Find: Which expression is equivalent to 7a^2b + 10a^2b^2 + 14a^2b^3

Solution:

7a^2b + 10a^2b^2 + 14a^2b^3

Take a^2 as common

a^2(7b + 10b^2 + 14b^3)

Now take b as common

a^2b(7 + 10b + 14b^2)

Hence a^2b(7 + 10b + 14b^2) is  equivalent to 7a^2b + 10a^2b^2 + 14a^2b^3

At a local grocery store, apples cost $0.50 each and bananas cost $0.30 each. The expression 0.50x + 0.30y can be used to find t
JulsSmile [24]

(1) x represents the number of apples bought, y represents the number of bananas.

(2) each term represents the total costs of a given fruit, so 0.50x is the total cost of apples and 0.30y is total cost of bananas.

(3) The coefficients are unit prices: coefficient 0.50 is the price of 1 apple, 0.30 is the price of 1 banana.

alukav5142 [94]

Answer:

Z_{0.05}=1.645

Step-by-step explanation:

Given :In a recent questionnaire about food, a random sample of 970 adults were asked about whether they prefer eating fruits or vegetables, and 458 reported that they preferred eating vegetables.

To Find :What value of z should be used to calculate a confidence interval with a 95 % confidence level?

Solution:

Confidence level = 95 % i.e.0.95

So, significance level = 5% i.e. 0.05

So, the value of z corresponding to significance level 0.05 should be used  to calculate a confidence interval with a 95 % confidence level

So, Z_{0.05}=1.645

Hence z should be 1.645 to calculate a confidence interval with a 95 % confidence level.

The weight, w, in tons of a school bus is related linearly to its seating capacity, p. a 60-passenger bus weighs 10 tons, and an
lidiya [134]
The linear equation of relating two objects can be written in the form,
                                    y = ax + b 
Our x is the number of passenger and y is the weight (in tons). Using the first two conditions,
                                    10 = 60(a) + b
                                     13 = 84(a) + b
The values of a and b from the equations are 0.125 and 2.5. 
For 50-passenger bus,
                                    y = (50)(0.125) + 2.5
The value of y is 8.75.
