Answer:

The answer to your question is: d) 0.46x10^-4

Step-by-step explanation:

(1.15x10⁻⁷) / (2.5x10⁻³)

First, divide 1.15 by 2.5 1.15 / 2.5 = 0.46

Second, subtract the power -7 - (-3) = -7 + 3 = -4

Finally, express the number 0.46 x 10⁻⁴

a) 4.6x10^-10

b) 0.46x10^-3

c) 4.6x10^-3

d) 0.46x10^-4

lana [24]

Answer:

<em>The estimated sales were $260 million</em>

Step-by-step explanation:

Assume the endpoints of a segment are (x1,y1) and (x2,y2).

The midpoint (xm,ym) is calculated as follows:

$\displaystyle x_m=\frac{x_1+x_2}{2}$

$\displaystyle y_m=\frac{y_1+y_2}{2}$

The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:

$\displaystyle x_m=\frac{2008+2010}{2}=2009$

$\displaystyle y_m=\frac{240+280}{2}=260$

The estimated sales were $260 million

The daily high temperature on October 31 in a certain city is normally distributed with µ = 50 and σ = 8 . What is the probabili

tatyana61 [14]

Answer:

0.5328

Step-by-step explanation:

µ = 50

σ = 8

We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees

$P(46 < x< 58)$

Formula : $Z=\frac{x-\mu}{\sigma}$

at x = 46

$Z=\frac{46-50}{8}$

$Z=-0.5$

Refer the z table for p value

p value = 0.3085

at x = 58

$Z=\frac{58-50}{8}$

$Z=1$

Refer the z table for p value

p value = 0.8413

$P(46 < x< 58)=P(x$

Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
