Who do you write 23 3/8 as a decimal

Answers

Answer 1

Answer:

we know that

A mixed number is a combination of a whole number and a fraction

in this problem

$23(3)/(8)$ is a mixed number

$23$ is a whole number

and

$(3)/(8)$ is a fraction

$23(3)/(8)=23+(3)/(8) \n =23+0.375\n =23.375$

therefore

the answer is

$23 (3)/(8)$ as a decimal is equal to $23.375$

Answer 2

Answer:

The value of the number in decimal form is, 24.0

We have to give that,

Write the number 23 3/8 in decimal form.

Here, the number is,

⇒ 23 3/8

Change into improper fraction as

⇒ (23 × 3 + 8) / 8

⇒ (184 + 8)/8

⇒ 192/8

⇒ 96/4

⇒ 24

Therefore, The number in decimal form is, 24.0

Find an equation for the line that passes through the point (-3, 6), parallel to the line through the points (0,-7) and (4,-15). Write your answer in point-slope form.

Answers

1st we will have to find the equation of the points (0,-7)(4,-15)
find the slope 1st
slope = y2-y1/x2-x1
slope = -8/4
slope = -2
and we know that the y intercept is -7
thus
the equation would be
y = -2x - 7

now we need to find the equation of the line that passes throgh (-3,6) and parallel to the previous equation
since it is parallel to the previous equation then they have the same slopes
thus the slope is -2
now we need to use
y - y1 = m(x - x1) to determine the equation
subsitute the values of x1 and y1
and m is the slope
y - 6 = -2(x +3)
y - 6 = -2x -6
y = -2x
that's the equation!

Gloria says the two expressions 1/4(12x + 24) - 9x and -6(x + 1) are equivalent. Is she correct? Explain why or why not.

Answers

The first expression is equal to 3x + 24 - 9x, or 24 - 6x, and the second equation equals 6-6x. If you set them equal to eachother, you get 24 - 6x = 6 - 6x. The 6x's cancel out, so you're left with 24 = 6, which is not true. The expressions are not equivalent.

so first distribute
1/4(12x+24)=3x+8
so 3x+8-9x=8-6x

-6(x+1)=-6x-6
8-6x is not equal to -6-6x
so she is NOT correct, they are not equivilent

21,000 rounded to the nearest 10,000

Answers

The answer would be 20,000 because 21 is closer to 20 than 30.

The answer would be 20,000. Like rounding 21 to the nearest ten is 20 because it is lower than the middle number (25).

HELP PLEASE I WILL GIVE BEST ANSWERAngela is studying two types of birds. She measures the wingspan, in inches, of five Type 1 birds and five Type 2 birds.

What can she infer about the wingspans of the two types of birds?

Type 1: {18, 24, 20, 22, 26}
Type 2: {24, 21, 19, 26, 30}

A.
Type 1 and Type 2 birds have similar wingspan distributions.

B.
Type 1 and Type 2 birds have somewhat similar wingspan distributions.

C.
Type 1 birds and Type 2 birds do not have similar wingspan distributions.

D.
Type 1 birds and Type 2 birds have identical wingspan distributions.

Answers

Answer:

Step-by-step explanation:

The given data set for type 1 of birds is:

Type 1: {18, 24, 20, 22, 26}

Type 2: {24, 21, 19, 26, 30}

Mean of the type 1 data is:

$Mean=(18+24+20+22+26)/(5)=(110)/(5)=22$

Data $(x-{\overline{x})^2$

18 16

24 4

20 4

22 0

26 16

Now, mean average of squares is:

$m=(40)/(5)=8$

Standard deviation= $SD=√(8)=2.828$

Now, the difference of mean and its standard deviation of type 1 data set is:

=22-2.828

Difference =19.172

The given data set for type 2 of birds is:

Type 2: {24, 21, 19, 26, 30}

Mean of the type 2 data is:

$Mean=(24+21+19+26+30)/(5)=(120)/(5)=24$

Data $(x-{\overline{x})^2$

24 0

21 9

19 25

26 4

30 36

Now, mean average of squares is:

$m=(74)/(5)$

$m=14.8$

Standard deviation= $SD=√(14.8)=3.84$

Now, the difference of mean and its standard deviation of type 2 data set is:

=24-3.84

Difference=20.16

Since, the difference of mean and standard deviation of both type 1 and type 2 data set is different, therefore, Type 1 birds and Type 2 birds do not have similar wingspan distributions.

Hence, option C is correct.

Answer:

Type 1 and Type 2 birds have similar wingspan distributions.
