Given that a = 4.8 × 104 and that b = 8 × 10−3

Mathematics

Answer:

3.84 * 10^0

Step-by-step explanation

Given the following values;

a = 4.8 × 104 and that b = 8 × 10−3

We are to find the product ab

ab = (4.8 × 10^4)(8 × 10^−3)

ab = (4.8*8)(10^4 * 10^-3)

ab = 38.4 * 10^(4-3)

ab = 38.4 * 10^-1

ab = 3.84 * 10 * 10^-1

ab = 3.84* 10^0

<em>Hence the product in standard form is expressed as 3.84 * 10^0</em>

.Write the quadrants/axes in which the following points lie a) (2,-3) b)(0,8) c)(-1,-2) d)(4,7)
natka813 [3]

Answer:

[see below]

Step-by-step explanation:

Quadrant One has a positive value for both x and y. (+ , +)

Quadrant Two has a negative x value. (- , +)

Quadrant Three has a negative value for both x and y. (- , -)

Quadrant Four has a negative y value.  (+, -)

Therefore:

(2, -3) would be plotted in Q4. It does not lie on any axis.

(0, 8) would be on the positive y-axis. (0 is neither negative nor positive.)

(-1, -2) would be plotted in Q3.  It does not lie on any axis.

(4, 7) would be plotted in Q1.  It does not lie on any axis.

Television networks frequently run public opinion polls on issues of concern. One network conducted a scientific poll asking a q
kobusy [5.1K]

Answer:

Option d

Step-by-step explanation:

Given that television networks frequently run public opinion polls on issues of concern. One network conducted a scientific poll asking a question concerning the approval rating of the way President Obama was handling the Iraq War. At about the same time a second network ran an online poll using a very similar question.

Observed data is

Poll              Scien      Online total

   

approve    339   385      724

disapprove 780        573     1363

                 1119        958     2087

H_0: Both scientific and online are consistent\\H_a: not consistent

(Two tailed chi square test)

Let us find out expected and chi square

Expected = row total x column total/grand total

The cell count expected in the online poll for those who approve

=\frac{724*968}{2087} \\=333.94

chi square = 7.81

Hence option d is right.

Find COS Instructions: Find the value of the trigonometric ratio. Make sure to simplify the If needed
Paraphin [41]

Answer:

Sin A = 15 / 17

Step-by-step explanation:

Given a right angled triangle, we are to obtain the Sin of the angle A ;

Using trigonometry, the sin of the angle A, Sin A is the ratio of the angle opposite A to the hypotenus of the right angle triangle.

Hence. Sin A = opposite / hypotenus

Opposite = 15 ; hypotenus = 17

Sin A = 15 / 17

Round 69581.491337 to the nearest thousand.
Anika [276]

Answer:

7000

Step-by-step explanation:

lets start with 695

9 is the thousand

you check the number next to 9

less then 4 let it rest

more than 5 let it soar

something like that lol

anyways since 5 is next to the 9 we round up from 9 to the next number which is 10

so that changes the whole number to 7000

hope this makes sense!
