The side length is the square root of 8. Because the square has 4 equal sides, the side lengths must be equal. So the answer is approximately 2.83.
Answer:
decrease of 29.6%
Step-by-step explanation:
The percentage change can be calculated as ...
percent change = ((new value)/(old value) -1) × 100%
= (38/54 -1) × 100%
= -0.2963 × 100%
= -29.6% . . . . . . . . . negative means decrease
54 to 38 is a decrease of 29.6%.
Answer:
D
Step-by-step explanation:
The diagramatic representation of the life cycle of a darkling beetle is shown in the attached file below.
The metamorphosis of the darkling bettle takes four stages:
egg → larva → pupa→ adult
After laying the eggs by an adult darkling bettle, the eggs are encased in a fluid-like covering to prevent it from damage as a result of environmental factors. The egg metamorphosize into the larva stage; a period of feeding and growth. They then in turn proceed into the pupa stage where they are being enclosed in a cocoon. In the cocoon, they undergo modifications and become sexually matured before they enters into adulthood.
Thus, the stage that represent the change fromm larva to adult is the pupa stage and it is shown in the diagram as option D
B. 4 cm, 10 cm, and 15 cm
According to two sides, 4, and 10 cm, the third side has to be between
10-4 and 10+4
6<side length<14
However, the side length is 15 cm, greater than 14 cm, so it is not a triangle.
Hope this helps :)
Answer:
0.625± 1.645*0.0571
Step-by-step explanation:
First calculate the estimate as 72 petty cases and 45 are unsolved as follows :
estimate :72/45=0.625
the critical value is given by cumulative probability equal to the p* (critical probability) as ,
1)compute value for alpha =1-(confidence value /100).
=1-(90/100)=0.1
for critical probability as p*=1 - (alpha/2)=1 -(0.1/2)=0.95
for this critical value is denoted to central area ,
Z(alpha)=1.645
now the standard error :
s=
here p is estimate and q is probability of failure and n is total no of cases
s=
=0.0571.
