Answer:

1 9/10

Step-by-step explanation:

Rewriting our equation with parts separated

1+1/2+2/5

Solving the fraction parts

1/2+2/5=?

Find the LCD of 1/2 and 2/5 and rewrite to solve with the equivalent fractions.

LCD = 10

5/10+4/10=9/10

Combining the whole and fraction parts

1+9/10= 1 9/10

Solution by Formulas

Convert any mixed numbers to fractions.

Then your initial equation becomes:

3/2+2/5

Applying the fractions formula for addition,

2×5

= <u>15+4</u>

= 19/10

Simplifying 19/10, the answer is

1 9/10

Hope this helps!

You can change the denominator to 10 which will get you to 55/10 + 4/10. You can add these two together to get 59/10

Find the value of log(4) ∙ log(25) to five decimal places.

Fittoniya [83]

Answer:0.84164

Step-by-step explanation:

Given

$\log \left ( 4\right )\cdot \log \left ( 25\right )$

we know

$\log a^b=b\log a$

Applying this identity we get

$\log \left ( 2\right )^2\cdot \log \left ( 5\right )^2$

$=2\log \left ( 2\right )\times 2\log \left ( 5\right )$

$=4\times \log \left ( 2\right )\cdot \left ( 5\right )$

$=4\times 0.301029\times 0.698970$

$=0.84164$

Can anyone help me out on this question?

svp [43]

Firstly , we will check continuity at x=1

we can use method

Suppose, f(x) is continuous at x=c

then it must satisfy

$\lim_{x \to c} f(x)=f(c)$

$\lim_{x \to 1} f(x)=f(1)$

firstly , we can find limit

$\lim_{x \to 1-} f(x)= \lim_{x \to 1-}(x+3)=1+3=4$

$\lim_{x \to 1+} f(x)= \lim_{x \to 1-}(3x+1)=3*1+1=4$

so, we get

$\lim_{x \to 1} f(x)= 4$

now, we can find f(1)

$f(1)=3*1+1=4$

so, we got

$\lim_{x \to 1} f(x)=f(1) =4$

so, this is continuous at x=1

Hence , option-D...........................Answer

A bottler of drinking water fills plastic bottles with a mean volume of 1001 milliliters (ml) and standard deviation of 6 ml. th

Alex73 [517]

The formula for z-score is:

z-score = (X – μ) / σ

where,

X = sample

μ = mean = 1001

σ = standard deviation = 6

Since we are looking for volumes less than 1001 mL, let us use 1000.5 mL for X.

z-score = (1000.5 – 1001) / 6

z-score = -0.083

Referring to the standard distribution table for z-test, this corresponds to:

p = 0.4681

<span>So 46.81% of the bottles are less than 1001 mL.</span>

PLS HELP Find the area of the shaded region. PLEASE

anastassius [24]

<h3>Answer: 64 cm^2</h3>

Reason:

The parallelogram has area of A = base*height = 10*7 = 70 cm^2

The white rectangle has area of B = base*height = 3*2 = 6 cm^2

The shaded region has area of A - B = 70 - 6 = 64 cm^2

If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
