Answer:

b=19

Step-by-step explanation:

We are given that an equation

$2x(3x+5)+3(3x+5)=ax^2+bx+c$

Given that the equation is true for all x

We have to find the value of b

$2x(3x+5)+3(3x+5)=ax^2+bx+c$

$6x^2+10x+9x+15=ax^2+bx+c$

$6x^2+19x+15=ax^2+bx+c$

Comparing coefficients of $x^2$ xand constant value on both side then we get

$a=6,b=19,c=15$

Hence, the value of b=19

roger goes shopping and buys an $112 item but has 30% off coupon. if tax is 7%, how much will roger pay altogether?

Yakvenalex [24]

Step-by-step explanation:

Cost = $112

30% discount coupon on the item he's going to buy

=$112 × 30/100 (or you can write 30%)

=$168/5 ($33.6)

7% tax on the item=$112 × 7/100(or you can write 7%)

= $196/25 ($7.84)

Total amount altogether=$112 - $33.6 - $7.84

=$70.56

not sure for the answer^^

It is known that 60% of customers will need additional maintenance on their vehicle when coming in for an oil change. A random s

inn [45]

Answer:

the probability that more than 70% of customers in the sample will need additional maintenance is 0.0371

Step-by-step explanation:

From the information given:

we are to determine the probability that more than 70% of customers in the sample will need additional maintenance

In order to achieve that, let X be the random variable that follows a binomial distribution.

Then X $\sim$ Bin(48, 0.6)

However 70% of 48 samples is

= 0.7 × 48 = 33.6 $\simeq$ 34

Therefore, the required probability is:

= P(X> 34)

$= \sum \limits ^{48}_{x=34} (^{48}_{x}) (0.6)^x(1 - 0.6)^{48-x}$

$= \dfrac{48!}{34!(48-34)!} (0.6)^{34} (0.4)^{48-34}$

$= 4.823206232 \times 10^{11} (0.60)^{34}(0.4)^{14}$

= 0.03709524328

$\simeq$ 0.0371
