43/8 - 13/8= 30/8

simplify 3 6/8 which will be 3 3/4

the answer is 3 3/4

Hey!

$5 \frac{3}{8} - 1 \frac{5}{8}$

Since 3 is less than 5, change 5 3/8

$5 \frac{3}{8} = 4 \frac{11}{8}$

Here is the new equation:

$4 \frac{11}{8} - 1 \frac{5}{8} = 3 \frac{6}{8}$

Simplify:

$3 \frac{6}{8} = 3 \frac{3}{4}$

$\framebox{Answer = B}$

Is the following conditional true? If p<2, then p≤2.

Romashka-Z-Leto [24]

If this is the only information you are given then no. This is because the < sign means that p is less than 2. The second sign cannot be true if the first one is because the second sign says that p is less than or equal to 2.

A rectangular field is 0.45 Kilometers long and 0.4 Kilometers wide. What is the area of the field in square meters? Do not roun

nikitadnepr [17]

We have the formula: Area= width x length
And we have Area= 0.45 x 0.4= 0.18 km²= 0.18x1,000,000= 180,000 m²
That is your number

The principal at Riverside High School would like to estimate the mean length of time each day that it takes all the buses to ar

Lilit [14]

Answer:

C) 11

Step-by-step explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

Since the Confidence is 0.90 or 90%, the value of $\alpha=0.1$ and $\alpha/2 =0.05$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that $z_{\alpha/2}=1.64$
