Answer: $169
Step-by-step explanation: The expression 25 + 18 x 8 represents the amount she will pay if she participates for 8 months.
Multiply 18 x 8 to find the cost for 8 months. $18 x 8 = $144.
Now add $25 to $144, which equals $169
the correct answer for this problem: x= -1/3y + 2
Let’s solve for x
3x + y= 6
Add -y to both sides
3x + y + -y = 6+ -y
3x = -y + 6
Divide both sides by 3
3x/3 = -y + 6/ 3
And so your answer is at the top hope this helps.
Answer:
5%
Step-by-step explanation:
The 68-95-99.7 rule for the Normal distribution is an empirical rule that remind us the percentages of data that falls between the mean ± 1, ± 2 and ± 3 standard deviations.
That is to say, if the mean is m and the standard deviation s, roughly speaking 68% of the data falls between [m-s, m+s], 95% between [m-2s, m+2s] and 99.7% between [m-3s, m+3s].
Since the mean is 3.0005 and the standard deviation is s=0.0010, 2s=0.0020, 95% of the data should fall between [3.0005-0.0020, 3.0005+0.0020] and 5% outside this interval. So <em>around 5% of total production will be scrap</em>.
Answer:
4:5
Step-by-step explanation:
If there are 12 boys and 15 girls, the ratio of boys to girls will be 12:15.
However, this can be simplified by dividing each number by 3. This can be done since both 12 and 15 are divisible by 3.
12:15
= 4:5
So, the ratio of boys to girls in Timara's class is 4:5
