Evaluate the expression for x=5 and z = 4 2xz-3x

1 answer:

5 0

So u take X and Z and plug them in, 2*5*4-3*5......5*4=20*2=40.....then 3*5=15 so 40-15=25, someone plz correct me if wrong.

Step-by-step explanation:

according to bodmas .... brackets come first so the numerator (2-7)²+5 is 2-7= -5² hence -25 +5
so the answer to the numerator becomes -25 +5 which is -20
so u get -20/3 which when simplified u will obtain -6 and 2/3

In the figure, angle D measures 71° and angle G measures 37°. What is the measurement of angle A?

HACTEHA [7]

Answer:

34 °

Step-by-step explanation:

∠D = 71°

∠G = 37°

In ΔGEF

Using angle sum property of triangle : Sum of all angles of triangle is 180°

∠G+∠E+∠F = 180°

Since ΔGEF is right angled triangle at F so, ∠F = 90°

Now, 37°+∠E+90° = 180°

127°+∠E= 180°

∠E= 180°-127° =53°

Now ∠E+∠D = 53°+71° = 124°

Now using exterior angle property in ΔABC

An exterior angle of a triangle is equal to the sum of the opposite interior angles

∠E+∠D is the exterior angle of ΔABC

So, ∠A+∠B = ∠E+∠D

since ΔABC is right angled triangle at B so, ∠B = 90°

∠A+90° = 124°

∠A = 124°-90°

∠A = 34°

Hence the measurement of angle A is 34 °

Here are the city gas mileages for 13

r-ruslan [8.4K]

The third quartile is 23

Step-by-step explanation:

To find the third quartile of set of data do that:

Arrange the data from smallest to largest
Find the median of the data (middle number)
The 3rd quartile (Q3) is the median of the upper data, (the upper data is the data after the median of the data)

∵ The city gas mileages for 13 different midsized cars in 2008

are 16, 15, 22, 21, 24, 19, 20, 20, 21, 27, 18, 21, 48

- Arrange the data from smallest to largest

∴ 15, 16, 18, 19, 20, 20, 21, 21, 21, 22, 24, 27, 48

∵ The set has 13 numbers

∴ The middle numbers is the 7th

∵ The 7th number is 21

∴ The median of the set is 21

∵ The upper data is the data after the median

∴ The numbers of the upper data are 21, 21, 22, 24, 27, 48

∵ The upper data has 6 numbers

- The median is the average of the middle two numbers

∴ The middle numbers are 22 and 24

∵ Their average = $\frac{22+24}{2}$ = 23

∴ The median of the upper data is 23

- The median of the upper data is the third quartile

∴ Q3 = 23

The third quartile is 23
