In a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 ord

postnew [5]

Answer:

The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

Step-by-step explanation:

Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.

Sample proportion $p=0.092\\q=1-p = 0.908\\n = 371$

$H_0: p =0.10\\H_a: p \neq 0.10$

(Two tailed test at 5% significance level)

p difference = $0.092-0.100\\=-0.0084$

Std error if H0 is true = $\sqrt{\frac{0.1(0.9)}{371} } \\=0.016$

Test statistic Z = p diff/std error

=0.539

p value = 0.5899

Since p > 0.05 accept null hypothesis

The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

Answer:

AB = 14

DE =7

Step-by-step explanation:

Remark

Opposite sides of a parallelogram are equal.

AB = CD

AB = 14

According to the diagram AE = 19

AD = 26 which is the same size as BC

DE = 26 - 19 = 7

DE = 7

Find the factors of the polynomial 4x²+ y²+ 4xy +8x +4y +4

nadya68 [22]

$4x^2+y^2+4xy+8x+4y+4\\\\=\underbrace{(2x)^2+2\cdot2x\cdot y+y^2}_{(a+b)^2=a^2+2ab+b^2}+8x+4y+4\\\\=\underbrace{(2x+y)^2+2(2x+y)\cdot2+2^2}_{(a+b)^2=a^2+2ab+b^2}\\\\=[(2x+y)+2]^2=(2x+y+2)^2$
