You have to multiply 15 by 32 and you get 480 which means the publisher shipped 480 books to the bookstore
Answer:
The right answer is "
".
Step-by-step explanation:
The given values are:
![\bar{x_0} = 3.7](https://tex.z-dn.net/?f=%5Cbar%7Bx_0%7D%20%3D%203.7)
![s_o=4.95](https://tex.z-dn.net/?f=s_o%3D4.95)
![t_{\frac{0.05}{2} }=2.2621](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B0.05%7D%7B2%7D%20%7D%3D2.2621)
As we know,
95% confidence for
will be:
= ![\bar{x_0} \pm t_{\frac{0.05}{2} },n-1\times \frac{s_o}{\sqrt{n} }](https://tex.z-dn.net/?f=%5Cbar%7Bx_0%7D%20%5Cpm%20t_%7B%5Cfrac%7B0.05%7D%7B2%7D%20%7D%2Cn-1%5Ctimes%20%5Cfrac%7Bs_o%7D%7B%5Csqrt%7Bn%7D%20%7D)
The lower bound will be:
= ![3.7-2.2621\times \frac{4.95}{\sqrt{10} }](https://tex.z-dn.net/?f=3.7-2.2621%5Ctimes%20%5Cfrac%7B4.95%7D%7B%5Csqrt%7B10%7D%20%7D)
= ![0.16\simeq 0.2](https://tex.z-dn.net/?f=0.16%5Csimeq%200.2)
The upper bound will be:
= ![3.7+2.2621\times \frac{4.95}{\sqrt{10} }](https://tex.z-dn.net/?f=3.7%2B2.2621%5Ctimes%20%5Cfrac%7B4.95%7D%7B%5Csqrt%7B10%7D%20%7D)
= ![7.23\simeq7.2](https://tex.z-dn.net/?f=7.23%5Csimeq7.2)
Thus the right answer is "
"
Step-by-step explanation:
replace the value of x with 1
y + 0.5 × 1 × y = 1 + 2
do the maths
y + 0.5y = 3
here the value of y is equal to 1. same goes for x, if we have no given value for them.
1.5y = 3
y = 3/1.5
y = 2
Answer:
The scale factor is 1.5.
Step-by-step explanation:
Divide the length of the image, 12, by the length of the preimage, 8, which will give you 1.5
12 ÷ 8 = 1.5
Therefore, the scale factor of the image is 1.5.
