Answer:

f(0) = g(0)

Step-by-step explanation:

if a function h(x) passes through [a,b] then it can be said that h(a)=b.

given that, g(x) passes through (-2,0) and (0,4)

so, g(-2)=0, g(0)=4.

f(x) passes through (0,4) and (2,0)

so, f(2)=0, f(0)=4

therefore, f(0)=g(0)=4.

so, first option is correct.

Step-by-step explanation:

How many more barrels of gasoline then diesel were produced last year gasoline 34% diesel 29% total crude oil -60 million barrel

MArishka [77]

Answer: 3 million barrels

Step-by-step explanation:

Given :- Total crude oil= 60 million barrels

Quantity of gasoline = 34% of total crude oil

$=0.34\times60\text{ million barrels}\\=20.4\text{ million barrels}$

Quantity of diesel = 29% of total crude oil

$=0.29\times60\text{ million barrels}\\=17.4\text{ million barrels}$

Clearly, Quantity of gasoline is more than Quantity of diesel

difference = Quantity of gasoline-Quantity of diesel

$20.4\text{ million barrels}-17.4\text{ million barrels}\\=3\text{ million barrels}$

Therefore, The production of gasoline is 3 million barrels more than diesel last year.

a random sample of n=24 data from a normal distribution with unkown variance produced x=42.5 and s=26 what is the 95 confidence

iogann1982 [59]

Answer:

95% of confidence intervals are

(31.5215 , 53.4785)

Step-by-step explanation:

Explanation:-

Given sample size 'n' =24

Mean of the sample x⁻ = 42.5

Standard deviation of the sample 'S' = 26

95% of confidence intervals are determined by

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} })$

Degrees of freedom

ν =n-1 = 24-1 =23

$t_{0.05} = 2.0686$

95% of confidence intervals are

$(42.5 - 2.0686 \frac{26}{\sqrt{24} } , 42.5+ 2.0686 \frac{26}{\sqrt{24} })$

( 42.5 -10.9785 ,42.5 +10.9785)

(31.5215 , 53.4785)
