1 + 1 2 ⋅ (4x − 6) = −2

Dmitry [639]

1.4375

<u>Step-by-step explanation:</u>

Step 1:

Let the given equation be $1+12(4X-6)=-2$

To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.

Step 2:

Let us expand the equation as $1+ (12*4X)-(12*6)=-2$

Step 3:

Let us expand it further as $1+48X-72=-2$

Step 4:

To find X segregate X in one side and all other remaining terms in other side as follows

$48X=-2+72-1$

After the simplification the numerical value is

$48X=69$

Step 5:

Keep X along one side and bring 48 to the denominator of another side to find X as follows

$X=69/48$

And the value of X is 1.4375

The average mark of candidates in an aptitude test was 128.5 with a standard deviation of 8.2.Three scores extracted from the te

Luba_88 [7]

Answer:

102

Step-by-step explanation:

We have the mean (m) 128.5 and the standard deviation (sd) 8.2, we must calculate the value of z for each one and determine whether or not it is an outlier:

z = (x - m) / sd

In the first case x = 148:

z = (148 - 128.5) /8.2

z = 2.37

In the second case x = 102:

z = (102 - 128.5) /8.2

z = -3.23

In the first case x = 152:

z = (152 - 128.5) /8.2

z = 2.86

The value of this is usually between -3 and 3, therefore when x is 102 it goes outside the range of the value of z, which means that this is the outlier.

The pie chart below illustrates the future plans of 200members of St.Thomas graduating class.

ruslelena [56]

Answer:

<h2>a) approximately 133 graduates</h2><h2>b) approximately 120°</h2>

Step-by-step explanation:

a) the number of graduates planning to continue studying :

= (37 1/2% + 12 1/2% + 16 2/3%) × 200

$=\frac{\left( 37\frac{1}{2} +12\frac{1}{2} +16\frac{2}{3} \right) }{100} \times200$

= (37.5 + 12.5 + 16.666666666667)×2

= 133.333333333334

…………………………………

b) the measurement of the angle representing those who plan to work :

= (360× 33 1/2)÷100

= (360× 33.333333333333)÷100

=119.999999999999

How would you round 95687 to the nearest thousand?

andre [41]

Answer:

96,000

Step-by-step explanation:

To round to the nearest thousand, we need to look at the digit in the hundreds place, which is 6. Since 6 > 5, we know that we need to round up (because 6 is closer to 10 than it is to 0). Currently, the number is 95 thousand so when rounding up, the answer will be 96,000.
