Answer:

i. 37, 788

ii. 38, 222

iii. 37, 900

Step-by-step explanation:

Rounding number can be very easy to work with in the head. The rounded number is the approximate value.To round a number to the nearest thousand simply means making the last three digit into the next lower number that ends in 000. Example round 6897 to the nearest thousand . The last three digits 897 depict that 6897 is more closer to 7000 than 6000 so, the nearest thousand of that value (6897) will be 7000.

The number can be either rounded up or down to the closest thousand depending on the closest to the nearest thousand. 6347 tot the closest thousand will be 6000 . Notice that the last three digits(347) indicate that the number (6347) is more closer to 6000 than 7000.

From the example above the three numbers that can be rounded to 38 000 are

i. 37, 788

ii. 38, 222

iii. 37, 900

Estimate 58% of 121 by using 10%

kvv77 [185]

58% is about equal to 60%, 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18

lina2011 [118]

Using normal distribution $\alpha = 1-0.95=0.05$
critical probability $p^{*} = 1 - \frac{ \alpha }{2}$
critical value for the critical probability is CV = 1.96
standard error $SE = \frac{3.2}{ \sqrt{41} } = 0.5$
margin of error = CV*SE = 1.96 * 0.5 = 0.98
95% confidence interval is between μ + 0.98 and μ - 0.98, which is (19.62, 21.58)

Ten young adults living in California rated the taste of a newly developed sushi pizza topped with tuna, rice, and kelp on a sca

timurjin [86]

Answer: For California: μ = 33.1; σ² = 1120.50; Range = 32;

For Iowa: μ = 24.5; σ² = 32.73; Range = 19

Step-by-step explanation:

Mean is the average of a population or a sample. It is defined as

μ = ∑x / n, where

x is each number of the set;

n is the total individuals in the sample.

Calculating the Mean for sample of taste of pizza in California:

μ₁ = $\frac{34+39+40+46+33+31+34+14+15+45}{10}$ = 33.1

Calculating the Mean for the sample in Iowa:

μ₂ = $\frac{28+25+35+16+25+29+24+26+17+20}{10}$ = 24.5

Variance measures how far the number in the set is from the mean. Its formula is

σ² = (∑x-μ)² / n -1

which means to find the variance, you have to get the difference between the number and the mean, square the result, add all of them and then divide by (n-1) individuals.

The Variance for the sample in California is

σ² = $\frac{(34 - 33.1)^{2}+(39-33.1)^{2}+(40-33.1)^{2}+(46-33.1)^{2}+(33-33.1)^{2}+(34-33.1)^{2}+(14-33.1)^{2}+(15-33.1)^{2}+(45-33.1)^{2}}{9}$ σ² = 120.50

The Variance for the sample in Iowa is

σ² = 32.73

Range is the difference between the highest and the lowest number of the set: range = highest - lowest

For the sample in California, the Range is

range = 46 - 14 = 32

For the sample in Iowa:

range = 35 - 16 = 19

For California:

Mean = 33.1;
Variance = 120.50;
Range = 32;

For Iowa:

Mean = 24.5;
Variance = 32.73;
Range = 19;

Which is the graph of linear inequality x – 2y ≥ –12?

galben [10]

Answer:

option D

Step-by-step explanation:

x-2y≥-12

-2y≥-x-12

y≤0.5x+6

has to be a solid line since y is less than or equal to 0.5x+6

so, options 1 and 3 are not applicable

also, in y≤0.5x+6 , y is less than or equal to this line, thus it only exists on the line and to the right of it (below it)

so, option 2 is wrong also, leaving us with option 4 or D, which in this case is the answer

I attached a file of this inequality's graph to prove my answer once more
