Answer:
The answer is 2.29 !
Step-by-step explanation:
To round 2.294 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part. We use the following rules to round 2.294 to the nearest hundredth: A) If the last digit in the fractional part of 2.294 is less than 5, then simply remove the last the digit of the fractional part
Can someone please help. I'm offering a lot of points because this answer needs an explanation. Statement proof style would be helpful, but it's not totally needed
Answer:
See below
Step-by-step explanation:
Given∠A ≅ ∠B and CD⊥ABTo prove CD bisects ∠ACBSolutionAs CD⊥AB, ∠BDC = ∠ADC = 90°
∠BDC ≅ ∠ADC
∠BCD = 180 - (∠BDC + ∠DBC)and
∠ACD = 180 - (∠ADC + ∠DAC)We can substitute ∠ADC with ∠BDC and ∠DAC with ∠DBC
Then we get same equation for ∠BCD and ∠ACD
Therefore ∠BCD = ∠ACD = 1/2∠ACB
It proves that CD bisects ∠ACB
Solve for x.
4x +15 > 23
Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
Answer:
Step-by-step explanation:
4x + 15 > 23
4x > 8
x > 2
X+y+z=2
-x+3y+2z=8

In the coordinate plane, the point X (2, 3) is translated to the point x'(5,-2). Under the same translation, the points Y(-1, 1) and Z(5, 5) are translated
to Y' and Z', respectively. What are the coordinates of Y' and Z'?
Add steps to solve !! Please
Answer:
Y'=(2,-4)
Z'=(8,0)
Step-by-step explanation:
X + T = X'
(2,3) + (T) = (5,-2)
T = (3,-5)
Y' = Y + T = (2,-4)
Z' = Z + T = (8,0)

-5+2a=4a-4-3a help plz and thank you
Answer:
a=1
Step-by-step explanation:
To make this easier, combine like terms first.
-5+2a=4a-4-3a
-5+2a=a-4
Then, add 5 on both sides.
-5+2a=a-4
+5 +5
2a=a+1
Now, subtract a on both sides.
2a=a+1
-a -a
a=1

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.25 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 36
.a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 36
The value of the mean is
μ=___ peas.
The value of the standard deviation is
σ=___peas.
b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.
Values of ___ peas or fewer are significantly low.
Values of ___ peas or greater are significantly high.
c. Is a result of 2 peas with green pods a result that is significantly low? Why or why not?
The result (is, is not) significantly low, because 2 peas with green pods is (greater than, equal to, less than) peas.
Answer : A) mean : 9, std = 2.6
B) significantly low value : = 3.8, significantly high value = 14.2
C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods
Step-by-step explanation:
given data :
probability ( p )= 0.25
number of groups ( n )= 36
A ) i) Mean of the of the peas ( u )
u = np = 36 * 0.25 = 9
ii) standard deviation of the peas ( б ) = [tex]\sqrt{np(1-p)} = \sqrt{9(1-0.25)}[/tex] = 2.60
B) Using the range rule of thumb to find the values separating results that are significantly low or significantly high.
note : assuming z = 2 and error = 5%
i) The values that are significantly lower
u - zб = 9 - (2*2.6 )
= 3.8
ii) The values that are significantly higher
u + zб = 9 + (2*2.6)
= 14.2
C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods

Answer:
sin = -√3/2cos = -1/2tan = √3sec = -2csc = (-2/3)√3cot = (√3)/3Step-by-step explanation:
See the attached picture for a drawing of the angle and its terminal point coordinates. Those are (cos(4π/3), sin(4π/3)), so we have the following trig function values:
sin(4π/3) = -√3/2
cos(4π/3) = -1/2
tan(4π/3) = sin/cos = √3
sec(4π/3) = 1/cos = -2
csc(4π/3) = 1/sin = -(2√3)/3
cot(4π/3) = 1/tan = (√3)/3

It helps to know that 1/√a = (√a)/a. This lets you write the ratios with a rational denominator in each case.

if 5x-7=13, what is the value of 10x-14
Answer:
10x-14=26
Step-by-step explanation:
x = 4
10 x 4 = 40
40 - 14 = 26
Answer:
26
Step-by-step explanation:
In order to answer this question, we must first find what x equals, so we need to solve for x in the equation 5x - 7 = 13:
5x - 7 = 13
+7 +7
5x = 20
/5 /5
x = 4
Now, we plug in 4 for 'x' in the equation 10x - 14:
10(4) - 14 =
40 - 14 =
26
So, 10(4) - 14 = 26
